iPadOS 17 (derivative for iPad)

iOS 17 is the seventeenth major release of Apple's iOS operating system for the iPhone. It is the direct successor to iOS 16. It was announced on June 5, 2023, at Apple's annual Worldwide Developers Conference alongside watchOS 10, iPadOS 17, tvOS 17 and macOS Sonoma. It was made publicly available on September 18, 2023, as a free software update for supported iOS devices (see the supported devices section).[3] It was succeeded by iOS 18 on September 16, 2024.

Early development

[edit]

iOS 17's internal codename is Dawn.[4] Apple initially intended iOS 17 as a "tuneup release", similar to iOS 12, Mac OS X 10.1, Mac OS X Jaguar, and Mac OS X Snow Leopard, allowing them to focus on their new Apple Vision Pro mixed reality headset, though they added major features later in the development cycle.[5][6]

System features

[edit]

Home Screen

[edit]
  • Home and Lock screens widgets are now interactive. For example, a user can turn on lights or open shutters of a house by pressing the corresponding button of the Home widget, mark a task complete by pressing directly on a reminder in the widget, etc.[7][8]
  • Spotlight search now allows users to change system settings directly from the search results. For example, if a user searches for "wifi" from the Home Screen, the switch to turn the Wi-Fi off or on appears in the search results.
  • The brightness of the wallpaper image changes depending on the dark or light mode, instead of being the same on both.[9]
  • Resized photos are now automatically extended to the top with a gradient that fills the missing space.[10]
  • Live wallpapers return after being removed from iOS 16, though they must now be selected separately from other photos and only animate when the phone is turned on.[11]

StandBy

[edit]
  • StandBy is a new feature automatically enabled when the phone is charging while horizontally oriented. It displays information via widgets in intelligent stacks, live activities, photos, the date, the clock, etc. The appearance of this information changes according to the ambient light, with dimmer and less flashy colors appearing at night.[12]

Autocorrect and text prediction

[edit]
  • The keyboard's autocorrection and dictation are powered by a new on-device transformer model, which is advertised to be more accurate and personalized to users' writing styles.[13][14]
  • Unlike previous versions of iOS, it can learn not to autocorrect swear words.[13][15]
  • Autocorrected words are underlined and can be reverted with a tap.[16]
  • Word predictions are shown inline as grey letters that are added when the spacebar is tapped.[17][18]
  • As of iOS 17.2, the option to turn off inline predictions without turning off predictive text was added, which allows the user to switch autocorrect to that of its functions in versions prior to iOS 8.[19]

Translation

[edit]
  • Ukrainian was added for translation available system-wide, in Safari web pages, and in the Translate app, bringing the number of languages available to twenty.[20][21]

AirDrop

[edit]
  • With the addition of NameDrop, by tapping an iPhone or Apple Watch against another iPhone, users can start a file transfer, a shared activity with SharePlay, or exchange a customizable contact card.[22] (Using NameDrop with an Apple Watch requires iOS 17.1 and watchOS 10.1.)
  • As of iOS 17.1, AirDrop file transfers can continue over the Internet if users leave AirDrop range.[23][24]

Siri

[edit]
  • Users can now simply address Siri by its name instead of having to say "Hey Siri" to activate it.[25][7]
  • Subsequent questions asked to Siri do not require the user to repeat the "Siri" command.[25]
  • The user can now say "Hey Siri, send a message" and then choose the application to use through a drop-down menu.[25] After the first change, Siri will remember the choice and speed up the operation.[25]
  • Users can ask Siri to read a page in Safari.[26]
  • Additionally, the ability to find a lost Apple TV remote with Siri was added.[27]

AutoFill

[edit]
  • The information saved by the user in Contacts can be used to automatically and securely fill in the fields of a form of a PDF or scanned document. Scanning documents take place in Notes.[28]

Accessibility

[edit]
  • A new feature called Personal Voice uses machine learning to let users recreate their own voice as a text-to-speech model.[29]
  • Using Point and speak, the phone will read what is written on the push-button panels of household appliances.[30]
  • A feature called Assistive Access is an extremely simplified iOS user interface that can be activated from the Accessibility settings, useful for people with cognitive disabilities.[31]

Networking

[edit]
  • A user can now connect an iPhone to a private 5G or LTE cellular network, using an eSIM or physical SIM that has been specifically provisioned for that network.[32]
  • There is also a new setting for cellular networks that allows users to disable cellular data usage statistics if they do not care which apps are consuming data.[33]

System settings

[edit]
  • In addition to an updated UI that shows more categories, the iPhone Storage section of the settings app now shows the space occupied by data shared between multiple apps from the same manufacturer.[34]
  • In the Haptic Touch duration settings, there is a third duration that is even shorter than the other two available in iOS 16.[35]
  • A new option for Focus mode notifications was added called Silence Notifications. This option lets the user choose if they want to mute notifications always or only when the device is locked.[36]
  • In iOS 17, the notification sound was changed from "Tri-tone", to "Rebound", which is noticeably quieter. As of iOS 17.2, the ability to change the default sound effect for third party apps was added, including the previously default "Tri-tone" option.[37]

Charging

[edit]
  • iPhone 15 models support Qi2 wireless charging. This was later added to the iPhone 13 and iPhone 14 models in the iOS 17.2 update.[38]

App features

[edit]

Phone

[edit]
  • With Contact Posters, users can now customize the appearance of the incoming call screen shown to other iPhone users.[39]
    • Customization options are similar to iOS 16's revamped lock screen, with the ability to pick a custom picture or Memoji as the contact photo, and change their name's font and color.
  • On the incoming call screen, a new Live Voicemail button sends the call to voicemail and shows a live transcript on-screen, so the user can decide whether to pick up the call.[40][41][42][43][44]
  • Other improvements:[45]
    • Different ringtones for each SIM.[46]
    • Increased number of memorized numbers in call history to 2,000.
    • Users can choose which SIM to use to call all unknown numbers.
    • The buttons to end a phone call, mute the microphone, etc. are positioned at the bottom instead of being in the center of the screen, so they are more accessible when using the phone with only one hand.
    • Added more than 20 new ringtones and 11 new alert tones, while moving the previous main ones into the classic section.[47]

Messages

[edit]
  • The Messages app has a new "Check In" feature.
    • The user must pick a contact and set a destination, and Check In notifies the contact once the user reaches the destination safely. If the user stops moving towards the destination and does not respond to prompts, the user's location, route, and battery level are automatically shared with the contact. The contact otherwise has no access to the user's location, and this information is end-to-end encrypted.[48][49][50]
  • Other improvements:
    • The Messages app also shows a transcript of voice messages.[51]
    • Emojis and photo cutouts (created through the "remove subject from background" tool) can be used as stickers, and stamped on bubbles in iMessage conversations or in other apps.[52]
    • In iOS 17.2, a new feature called contact key verification was added. This adds an extra layer of security to iMessages, as these keys are exchanged by users when they meet up in person or can be automatically shared with FaceTime, and if at any point a device not registered with the key sends a message, the other user will be notified.[53]

Journal

[edit]

Apple Music

[edit]
  • A new feature called a "Collaborative Playlist" allows a group of users to add and remove songs from a shared playlist. (This was removed in iOS 17.2 Beta 4,[56] but later re-added in 17.3)[57]
  • A new Crossfade effect between played songs, supporting a range between 1 second and 12 seconds.[58]
  • Animated album artwork in music player: albums that support animated album artwork will now show that animation in the music player on Apple Music.[59]
  • In iOS 17.1, the "Love" system in Apple Music was replaced by a "Favorites" section that comes with expanded functionality.[60]
  • In iOS 17.2, a Favorite Songs Playlist was added.[61]
  • With iOS 17.2, users can now disable Listening History in a focus mode.[61]

Apple Maps

[edit]
  • Maps can now be downloaded for use without an Internet connection.[62]
  • It is possible to see in real time the availability of charging points for electric vehicles, in particular how many free slots there are at that particular charging point, the type of connection, etc.[63]
  • Users can search people on the map by name if they have shared their location.[64]

Safari

[edit]
  • Safari supports Profiles to keep a user's browsing activities separate when they are at work or school from those at home or personal. Individual Safari extensions can be enabled or disabled by profile.[65][66]
  • Pages previously opened in Private browsing mode require Face ID to be reviewed.[67]
  • Any extension that can read info on a page the user visits is disabled by default when private browsing.[67]
  • Known trackers are blocked while private browsing and tracking IDs in links are automatically removed.[67]
  • In the Safari settings, users can set a separate search engine to use in private mode.[67]
  • Users are able to listen to an entire page as audio read from the phone.[68]
  • The browsing history now shows favicons next to the site name and description.[69]
  • Added support for JPEG XL and HEIC image formats.[70]
  • AV1 hardware decoding on iPhone 15 Pro and iPhone 15 Pro Max.[71][72]

Notes

[edit]
  • Users can create links between notes to quickly jump from one note to another.[73]
  • Users can view and annotate PDFs directly within the app.[74]

Reminders

[edit]
  • The list of a reminder can now be organized into sections.[73]
  • The Grocery list now automatically sorts grocery items into sections.[75]
  • There is a new column view.[76]

Photos

[edit]
  • Users can search for recipes on the Internet using a photo containing food.[77]
  • Dogs and cats are automatically recognized and categorized within the people section.[78]
  • When a user zooms in on a photo, a button automatically appears to crop the photo without having to go into photo editing first.[79]
  • In the search box, users can type the name of an object to find the exact frame in the video where that object appears.[80]
  • Visual Lookup is now able to recognize in photos the symbols of the various lights in the car, the symbols in the labels of clothes, etc.[81]

Camera

[edit]
  • The Camera app has two new optional settings: "Level" shows a horizontal line that turns yellow when the subject is aligned to the horizon, and "Lock white balance" can disable automatic white balance adjustments when recording a video.[82]
  • Deferred Photo Processing: the Deep Fusion post-processing process is performed in the background, instead of taking place at the same time as the "shot" and only when the camera is not in use. This ensures significantly higher recording sessions, without shutter blocks, allowing the user to capture new photos at any time.[83]

Weather

[edit]
  • A wind map has been added.[84]
  • The Weather app now lets users compare today's weather with yesterday's.[85]
  • Moon phase: a new section shows the current state of the moon, the time until the next full moon, the times of moonset and moonrise and the lunar calendar.[86]

Health

[edit]
  • The Health app lets users log and label their mood, and see how their mood correlates to various lifestyle factors over time.[87]
  • The app also let users take standardized assessments for anxiety and depression, although this information is not diagnosis and should not be treated as such.[88]
  • Users can be notified if they forget to log that they have taken their medication.[89]
  • Added summary of users' friends' training results.[90]

Shortcuts

[edit]
  • Commands associated with various apps are shown in Spotlight search when users search for that app. For example, when searching for the Camera app, commands to open the app in Selfie, Portrait, Cinematic, Time-Lapse, etc. modes are shown.[80]
  • Developers can define the background color of commands created for their app. For example, for the Books app, the commands to open the current book and listen to the current book appear in an orange box like the color of the Books app.[91]

Miscellaneous

[edit]
  • The Home app now includes an activity history for up to 30 days, so the user can see who's accessed the user's locks, doors and alarm sensors, and when.[92][93]
  • Apple Fitness+ can give users custom workout plans, set workouts or meditations to play consecutively, or separately change the volume of the music and the instructor's voice.[88]
  • A new feature called "screen Distance" checks and warns users if they are holding their Face ID-enabled iPhone too close to the user's face for a considerable period of time.
  • The Clock app now supports simultaneous timers.[94]
  • Find My supports sharing AirTags and similar third-party items with up to five people.[95]
  • FaceTime supports the ability for callers to leave a video or audio message when the recipient is unavailable. Effect reactions have been added to FaceTime calls, similar to the reactions feature in Messages.

Security and privacy

[edit]
  • One-time verification codes received in Mail can be filled in with a tap without leaving Safari.[96]
  • The ability to automatically delete verification codes was added.[97]
  • Link-tracking protection detects user-definable tracking parameters in link URLs and automatically removes them. It is automatically enabled in Mail, Messages, and when browsing with Safari in Private Mode.[98]
  • Shared group passwords allows the user to create groups of passwords to share with family and friends. Users can recover passwords for up to 30 days.[99]
  • After changing the lock screen passcode, the old code can be used for 72 hours to reset the new passcode if it is forgotten. There's also a button to expire the previous passcode immediately.[100]
  • iOS 17 contains several changes for app permissions. When an app wants to add an event to the user's Calendar, the event is added without the app being able to read the entire contents of the calendar. When apps ask to access the user's entire photo library, the user can share specific photos with apps while keeping the rest of the library private.[clarification needed]
  • A sensitive content warning detects nudity in photos and videos received in AirDrop and other apps, obscuring them with a blur effect before they are displayed.
  • Lockdown mode can block the iPhone from connecting to 2G cellular networks and from auto-joining insecure wireless networks, and it disables more APIs in Safari susceptible to being attacked, such as IndexedDB, File API, FileReader API, WebSpeech API, WebLocks API, and more. (Apple's simultaneously announced watchOS 10 gains support for Lockdown mode, and the mode is automatically enabled on Apple Watch when it is enabled on a paired iPhone.)[101]

European Union-specific changes

[edit]

In compliance with the Digital Markets Act, Apple introduced a set of additional features only for those living in European Union countries. These features were rolled out beginning with iOS 17.4.[102][103]

These include:

  • The installation of third-party alternatives to the App Store.
  • The ability to download web browsers that use web engines other than WebKit.
  • Management of default web browser settings.
  • The ability for a user to choose alternative payment methods to use in the app store.

Additionally, Apple has put in place measures to prevent all users outside of the EU from accessing any of those features.

These measures include:

  • Requiring a user's Apple ID region to be set to one of the EU’s 27 member states.
  • Performing routine on-device geolocation checks to ensure a user is physically present within the EU’s borders.
  • Making it so that users who travel out of the EU can continue accessing third-party app stores for a grace period of 30 days. Users who are away from the EU for more than 30 days will lose access to these features; they can continue using previously installed apps but are unable to update or install apps from third-party app stores.[104][105]

Initial plans to remove web apps

[edit]

With the second beta of iOS 17.4, the functionality of progressive web apps was severely restricted; web apps added to the home screen opened as bookmarks in the user's default browser. While this was initially believed to be a bug, Apple confirmed on February 15, 2024, that they would be removed, justifying their choice by low use, as well as security and privacy concerns and the Digital Markets Act.[106] On February 26, it was announced that the European Commission was planning to investigate Apple over the move, and requested more information from the company and app developers for further assessment.[107][108] The Open Web Advocacy wrote a letter to Tim Cook and asked him to not "sabotage" the feature.[109] On March 1, Apple announced that it had canceled its plan to disable home screen web apps in the European Union; Apple's developer website was then updated to reflect this.[110]

Privacy and security measures

[edit]

Apple has expressed concerns regarding the potential impact of third-party app marketplaces on user privacy and device security.[111] Allowing app installations outside the official App Store may increase the risk of malware, scams, and harmful content.[112] To mitigate these risks, Apple has implemented a notarization process that requires all apps—regardless of distribution channel—to undergo automated and human review to identify known security threats and ensure compliance with platform policies.[113] Additionally, third-party marketplace developers must adhere to strict operational guidelines, including providing transparency regarding data handling and ensuring mechanisms for user support and reporting abuse.[114] Despite these safeguards, Apple maintains that the changes may expose users to elevated security risks compared to the standard App Store environment.[112]

Known issues

Supported devices

[edit]

iOS 17 requires iPhones with an A12 Bionic SoC[a] or later. It drops support for iPhones with an A11 Bionic[b] SoC, officially marking the end of support for iPhones with a 5.5-inch display. iOS 17 is the first version of iOS to drop support for an iPhone with Face ID and no Home button. The iPhone SE (2nd and 3rd generations) are the only supported devices to feature Touch ID and the Home button.

However, iPhones with an A12 Bionic or A13 Bionic[c] SoC have limited support[d] while iPhones with an A14 Bionic SoC and later[e] are fully supported.[115]

iPhones that support iOS 17 are:[116][117][118]

Release history

[edit]

The first developer beta of iOS 17 was released on June 5, 2023.[40] Unlike previous years, the developer beta program is open to anyone with a free Apple Developer account, without requiring a subscription.[119]

Reception

[edit]

Reception for iOS 17 upon its release date was generally positive.[120][121][122] Critics praised the new Contact Posters, Check In, and StandBy mode. They also liked the improvements to stickers, widgets, text prediction, the Camera app, Shortcuts, verification codes, and the Reminders app.[122] However, many media outlets criticized the lack of the Journal app that was announced during the iOS 17 segment.[121][122] The Journal app was later released, first as part of the iOS 17.2 beta to developers and public beta testers, then to the general public as part of the iOS 17.2 stable release. Following the release of iOS 17, users reported overheating problems on newer devices such as iPhone 15 and iPhone 15 Pro,[123] and numerous glitches on older devices.[124][125]

Development

Announcement at WWDC 2023

Apple announced iOS 17 during the keynote address at its (WWDC) on June 5, 2023, held at in . The event, which ran from June 5 to June 9, 2023, primarily targeted developers but also served as a platform for previewing major software updates across Apple's ecosystem. iOS 17 was positioned as an update enhancing personalization and intuitiveness on the , with demonstrations focusing on redesigned interfaces for core apps. The announcement highlighted upgrades to communication features, including Contact Posters for customizable caller interfaces, expanded sticker options in Messages, and Live Voicemail for real-time transcription during calls. Additional previews included StandBy mode, which transforms the into a smart display when charging in landscape orientation, and a new Journal app for reflective logging with privacy-focused suggestions. received updates for more natural voice interactions, such as back-to-back requests without reactivation and improved context understanding. Following the keynote, Apple released the first developer beta of iOS 17 on June 5, 2023, allowing registered developers to test the software ahead of its public release later in the year. The update was compatible with iPhones from the onward, emphasizing incremental refinements over radical overhauls compared to prior versions. This announcement aligned with Apple's annual cadence of unveiling iOS updates at WWDC, providing developers to integrate new APIs and features.

Beta Testing Phases

The beta testing phase for iOS 17 began with the release of the first developer beta on June 5, 2023, immediately following the software's announcement at Apple's (WWDC) 2023 keynote. This initial build, available to registered Apple Developer Program members via over-the-air updates or direct downloads from the Apple Developer portal, focused on core features such as enhanced capabilities, customizable Lock Screens, and StandBy mode, allowing developers to assess compatibility with third-party apps and identify early stability issues. Subsequent developer betas were issued weekly or bi-weekly, with refinements addressing bugs like intermittent crashes in the Phone app and performance optimizations for older devices such as the ; by early August 2023, at least five developer betas had been distributed, incorporating iterative improvements based on developer-submitted feedback through Apple's Feedback Assistant tool. Apple's public beta program, designed for wider testing by non-developers enrolled via beta.apple.com, commenced with the first public beta on July 12, 2023, which mirrored developer beta 4 in build number and feature set. This phase emphasized real-world usage scenarios, gathering data on battery drain, overheating during extended sessions, and integration with features like NameDrop in , with public testers reporting issues such as delayed autocorrect learning that were subsequently patched in later iterations. Public betas continued in tandem with developer releases, reaching at least three versions by August 9, 2023, and providing Apple with diverse to refine security patches and UI responsiveness ahead of the stable launch. The testing culminated in a release candidate (RC) build in mid-September 2023, typically designated as the final beta equivalent to the general availability version, enabling final validation before the official release on September 18, 2023. Throughout both phases, Apple emphasized caution for participants, noting potential risks like or device instability, and no major delays were reported in the iOS 17 beta cycle compared to prior years, reflecting a streamlined refinement process driven by empirical bug reports rather than speculative redesigns.

Pre-Release Refinements and Delays

Apple issued multiple developer betas following the initial release on , 2023, with iterations typically spaced one to two weeks apart to incorporate feedback on stability, , and feature functionality. These updates addressed early reports of battery drain and UI glitches, such as frame drops, through incremental fixes refined based on developer testing. For example, iOS 17 beta 4, seeded to developers on July 25, 2023, introduced tweaks to the app drawer layout and expanded StandBy mode customization options, reflecting responses to usability feedback from prior betas. A re-release of beta 4 to developers occurred on July 31, 2023, coinciding with public beta 2, primarily to align builds and resolve minor synchronization issues encountered in initial testing, without altering core features. Subsequent betas, including beta 5 on August 8, 2023, continued this refinement by optimizing battery life and reducing bugs highlighted in user reviews of earlier versions, such as inconsistent autocorrect behavior and transfer delays. By beta 8, released August 29, 2023, the focus shifted to final polishing, with testers noting improved overall stability compared to beta 1, though some persistent issues like random app crashes remained under active resolution. The beta program adhered closely to Apple's standard timeline, with public betas following developer versions by approximately one week starting July 12, 2023, and no significant delays reported that altered the planned fall rollout. This iterative approach culminated in the release candidate on September 12, 2023, enabling a stable general availability launch on September 18, 2023, without postponements attributed to unresolved refinements.

System-Wide Features

Home Screen and Lock Screen Customizations

iOS 17 enables greater interactivity in widgets, allowing users to perform actions such as completing tasks, controlling media playback, or adjusting smart home devices directly from the widget without opening the full application. This represents an expansion from prior versions where widgets were primarily informational. Users can place widgets anywhere on the grid alongside app icons, supporting various sizes including small, medium, and large formats for compatible widgets, and organize them into Smart Stacks that automatically cycle through relevant content based on factors like time of day or location. Additionally, shaking after placing a widget triggers an option, facilitating easier experimentation with layouts. For the Lock Screen, iOS 17 builds on established customization options by integrating interactive widgets into the lower corners, where up to four small widgets can be added for at-a-glance information such as upcoming events, updates, or battery status, with direct interaction enabled similar to the . Users select wallpapers from photos, solid colors, gradients, or dynamic options, and customize the clock's appearance by choosing fonts, adjusting text thickness via a slider, and matching colors to the for stylistic consistency. The links to specific pages, enabling tailored experiences tied to Focus modes, though core layout constraints persist, such as fixed widget positions without freeform placement. These features emphasize utility and personalization while maintaining accessibility from the locked state.

StandBy Mode

StandBy Mode transforms the iPhone's into a customizable full-screen display for viewing information from a distance, functioning as a bedside clock, , or widget dashboard while the device charges in orientation. Introduced in iOS 17 and available on and later models, it activates automatically when the iPhone is locked, connected to power via cable or charger, positioned horizontally on a stable surface, and detects minimal motion. Users can enable or disable the feature in Settings > StandBy, and it can be triggered manually by tapping the screen, nudging the device, or invoking with commands like "Turn StandBy on." The mode supports swiping left or right to cycle through three primary views: customizable clock faces (including analog, digital, and styles), a slideshow of photos selected from the user's library or Favorites album with shuffle options, and full-screen widgets such as Smart Stacks, calendars, or weather updates that can be resized and arranged. It integrates Live Activities for real-time updates like sports scores or ride-sharing progress, displays incoming notifications and calls in larger format, and allows interaction via taps or for tasks like alarms or music control. Customization occurs through Settings > StandBy, where users select default views based on charging location (detected via positioning), adjust clock typography and colors, curate photo sources, and add widgets from the available library. Display behavior includes automatic activation after inactivity, with options set to "Automatically," "After 20 Seconds," or "Never" to keep the screen on; on and later models with hardware, it remains persistently visible at reduced brightness. In low-light conditions, Night Mode engages automatically, applying a red tint and inverting colors for reduced without manual intervention.

Keyboard Autocorrect and Predictive Text

iOS 17 introduced a redesigned autocorrect system powered by a language model, which enhances prediction accuracy by analyzing the broader context of typed text rather than relying solely on isolated words. This model enables the keyboard to better distinguish intentional slang, emojis, or proper nouns from errors, reducing erroneous corrections. The system now learns from user rejections of suggested corrections, applying those preferences persistently across applications to minimize repeated fixes for the same terms. These changes were announced at WWDC on June 5, 2023, and became available with the public release of iOS 17 on September 18, 2023. Predictive text in iOS 17 shifted to an inline display positioned directly above the keyboard keys, allowing users to tap suggestions seamlessly without disrupting typing flow. This integration with the updated autocorrect model provides more contextually relevant word predictions, drawing from the transformer architecture to anticipate phrases based on recent input patterns. Users can customize predictive behavior via Settings > General > Keyboard, where options to enable or disable are available, alongside toggles for auto-correction itself. Initial adaptation may require several weeks of usage for the model to refine suggestions to individual typing habits, as reported by Apple engineers. While Apple touted these updates as a "comprehensive" overhaul for more intuitive input, some users experienced inconsistent performance, such as over-aggressive corrections or irrelevant predictions shortly after updating, potentially due to the learning phase. Independent reviews noted improved long-term accuracy after adaptation, attributing gains to the neural network's ability to process multilingual inputs and user-specific data on-device for privacy. No widespread systemic failures were confirmed by Apple, and the features align with prior iOS evolutions emphasizing for text input.

Security and Privacy Measures

Core Security Enhancements

iOS 17 expanded Lockdown Mode, an optional extreme protection setting introduced in prior versions, to further mitigate sophisticated cyber attacks targeting high-profile individuals such as journalists and activists. The enhancements block most attachments in Messages to prevent zero-click exploits via malicious files, hide message previews in notifications to avoid information leakage, and disable just-in-time compilation in , reducing potential memory corruption vulnerabilities from web content. These measures prioritize causal reduction of attack vectors by limiting untrusted inputs and dynamic code execution, though they may disrupt normal functionality like link previews or certain web apps. Safari's Private Browsing mode received locking capabilities, requiring , , or passcode authentication to access tabs when the browser is backgrounded or the device is locked, preventing unauthorized viewing if the device is temporarily handed over. Additionally, iOS 17 automatically removes known trackers from URLs copied or shared across apps like Messages, Mail, and , diminishing cross-site behavioral profiling without relying on server-side blocking that could be evaded. This URL sanitization operates client-side, enforcing privacy through data minimization rather than detection alone, though its effectiveness depends on Apple's tracker database accuracy. Passkeys emerged as a core cryptographic upgrade, replacing traditional passwords with device-bound public-key pairs synced via and authenticated biometrically, rendering them phishing-resistant since secrets never leave the device. In iOS 17, and supported apps default to passkey creation where available, with cross-platform compatibility via QR codes or synced devices, empirically stronger against as demonstrated by reduced breach impacts in trials. Recovery options include escrow in but require account recovery keys, balancing usability against risks. iMessage Contact Key Verification, rolled out in , enables users to confirm that communications originate from devices holding verified public keys for contacts, alerting to potential man-in-the-middle interceptions or server compromises. Setup involves generating and sharing verification codes , with ongoing checks during sessions; this augments by verifying endpoint integrity, though adoption remains low due to setup friction. Empirical data from security audits indicates it effectively detects key rotation anomalies exploited in state-sponsored attacks. Verification codes for two-factor authentication auto-delete after one use in iOS 17, preventing reuse in automated attacks and reducing SMS-based success rates by limiting code persistence in Messages. This integrates with the Passwords app, which centralizes credential management with enhanced sharing controls, further hardening against lateral movement in breaches. Overall, these features emphasize proactive input validation and key hygiene over reactive patching, aligning with first-principles defense against common exploit chains like violations and credential compromise.

Privacy-Focused Features

iOS 17 enhanced user privacy through targeted improvements in prevention, controls, and on-device processing. A key update involved expanding Link Tracking Protection to automatically remove known trackers from URLs in Messages, , and , reducing the ability of third parties to monitor user activity across sites or apps. This feature processes links on-device without altering core functionality, preserving usability while limiting persistent identifiers. Safari's Private Browsing mode received bolstering measures, including locking of private windows behind , , or device passcode to prevent access by others using the unlocked . Private tabs now proactively block cross-site trackers from loading page content and warn users if switching from a private to a regular window, minimizing accidental exposure of browsing history. Additionally, iOS 17 introduced automatic deletion of verification codes after they are used or copied, mitigating risks from screen captures or unauthorized viewing of message history. For media and contacts, the Photos app added options to lock hidden albums, requiring biometric or passcode authentication for viewing, which extends beyond previous visibility controls. NameDrop, an extension, mandates explicit confirmation before sharing contact details or photos during device proximity interactions, preventing unintended data leakage in public settings. Lockdown Mode, designed for users facing sophisticated threats, was fortified with restrictions on just-in-time code compilation in and disabling of message attachment previews, further isolating potential exploits while maintaining core device operations. These updates prioritize on-device computation to avoid transmitting sensitive data to servers, aligning with Apple's framework for aggregate threat detection.

Developer and Ecosystem Security

In iOS 17, Apple mandated the use of manifests for third-party kits (SDKs), requiring providers to document data types collected, purposes for usage, and reasons for any tracking or linking to user identities. These manifests, embedded as plist files in SDKs, enable app developers to assess and disclose implications during submission, with non-compliance potentially leading to review rejection. This mechanism enhances ecosystem security by increasing transparency in the of app components, mitigating risks from opaque SDKs that could enable unauthorized or tracking. To curb device fingerprinting—a technique often used for persistent tracking without consent—iOS 17 enforces stricter justifications for APIs susceptible to such abuse, such as those accessing device signals or sensors. Developers must declare the necessity of these APIs in their app's nutrition labels and provide technical rationale during review, with Apple rejecting apps employing fingerprinting as a privacy-invasive alternative to like IDFA. This policy, rooted in App Store Guideline 5.1.3, strengthens the ecosystem against covert surveillance by third-party apps, preserving user anonymity while allowing legitimate uses like detection. Networking for developers was bolstered, with apps linked on or after iOS 17 defaulting to requiring secure () connections to external IP addresses, disallowing insecure HTTP unless explicitly excepted via the NSExceptionDomains key. This ATS (App Transport Security) evolution reduces man-in-the-middle vulnerabilities in app communications, compelling developers to prioritize encrypted data flows and thereby fortifying the broader app against network-based exploits. Additionally, support for EAP-TLS 1.3 in Network Extension frameworks improves enterprise . Authentication enhancements include expansions to the , enabling third-party apps to support passkeys—cryptographic credentials stored in the —for seamless, phishing-resistant logins across apps and websites. Developers can integrate ASAuthorizationPasswordProvider for managing passkeys, which leverage platform-level hardware security modules to prevent credential theft, thus reducing reliance on vulnerable passwords and elevating ecosystem-wide login security standards. These features collectively promote a more secure developer environment by embedding privacy-by-design principles and robust , while maintaining Apple's sandboxed app model to isolate potential threats.

Regulatory Compliance and Controversies

European Union DMA Requirements

The 's (DMA), adopted in 2022 and entering full application on March 2, 2024, identifies Apple as a "" for , the , and , effective September 5, 2023. The regulation mandates obligations to promote contestability and fairness, including allowing users to sideload apps from sources outside the , support third-party app marketplaces, enable alternative default browsers with non-WebKit engines, and permit developers to use or link to external payment systems for digital goods, while prohibiting anti-steering provisions that block notifications about cheaper alternatives. These rules aim to reduce Apple's control over app distribution and browser technologies but require gatekeepers to maintain baseline security and privacy standards. Apple's initial compliance materialized in iOS 17.4, released March 7, 2024, for EU iPhone users meeting hardware criteria ( or later models). This update introduced a dedicated settings screen for selecting alternative , which must undergo Apple's notarization process involving scanning and vulnerability checks prior to distribution; sideloaded apps face similar automated and human reviews. Developers opting for alternative distribution or payments incur a Core Technology Fee of €0.50 per annual install after the first million on an iOS device, calculated to offset infrastructure costs like fraud prevention and content moderation. Over 600 new APIs were provided for expanded analytics, on-device processing of payments, and browser engine customization, though Apple retained requirements for apps to request user consent for marketplace installations and comply with rules prohibiting unwanted . Apple contends that DMA-mandated changes elevate risks to users, including heightened exposure to —citing Android's 99% of mobile threats originating outside official stores—and forced data sharing that undermines features like Private Relay and contact key verification in . The company proposed modifications, such as limiting to opt-in scenarios, to preserve and device integrity, but these were declined by the , leading to ongoing specification proceedings for further clarification on obligations like browser choice screens and processing. By September 2024, Apple reported diminished user protections, such as reduced safeguards against in alternative browsers and increased cross-site tracking potential, attributing these to the regulatory framework's structure rather than implementation choices. Subsequent EU scrutiny resulted in a €500 million fine against Apple in April 2025 for incomplete compliance in areas like browser steering and terms.

Web Apps Removal Debate

In early 2024, as Apple prepared to release to comply with the European Union's (DMA), the company indicated that web apps—also known as Progressive Web Apps (PWAs)—would be disabled for users in the . Apple stated that this change was necessary because the DMA mandates equal treatment for all browsers, including the ability to use alternative rendering engines beyond Apple's . Under prior versions, web apps added to the via relied exclusively on , which Apple argued created an uneven playing field if third-party browsers with different engines could not similarly generate full-featured PWAs without additional development. Beta testing of confirmed the removal, with existing web apps reverting to mere shortcuts lacking standalone functionality, such as offline access or push notifications. The decision sparked significant debate among developers, web standards advocates, and regulators, who contended that the removal was not strictly mandated by the DMA but rather a strategic move by Apple to curtail competition from web-based alternatives to native apps. Critics, including European web developers, highlighted that PWAs enable cross-platform experiences without Apple's 30% commission fees, fostering innovation in areas like banking and apps that prefer web technologies for easier updates and broader reach. They argued Apple could have maintained WebKit-based PWAs for all browsers or adapted the feature to support engine choice without elimination, accusing the company of overinterpreting DMA requirements to protect its control. Proponents of Apple's position, including some experts, countered that PWAs pose risks like inconsistent privacy controls across engines and potential circumvention of vetting, which the DMA does not explicitly override. This tension underscored broader concerns about compliance, with the removal affecting an estimated thousands of users relying on PWAs for streamlined access to services like PWAs for sites such as or banking portals. The controversy intensified scrutiny on Apple's DMA implementation, as the web apps feature had been available since iOS 11.3 in 2018, predating the regulation. Developers reported immediate disruptions in 17.4 betas, where PWAs lost icon badges, standalone windows, and full-screen modes, prompting calls for intervention to clarify whether such functional downgrades align with the Act's anti-foreclosure goals. While Apple maintained the change ensured "equality" by not privileging Safari's engine, opponents viewed it as regressive, potentially stifling web in a market where native apps dominate due to platform lock-in. The debate highlighted DMA's intent to promote without unintended consequences for established features, with no formal ruling issued at the time on this specific provision.

Apple's Response and Reversal

In January 2024, Apple announced plans to discontinue web app support—also known as progressive web apps (PWAs)—for iOS users in the with the upcoming iOS 17.4 release, citing compliance challenges under the (DMA). The company stated that web apps, which rely on (the engine powering ), could not meet DMA requirements for alternative browser engines without risking user privacy and security, as third-party browsers would not have equivalent controls. This move was criticized by developers and users for limiting competition and forcing reliance on native apps, potentially preserving Apple's 30% commission on in-app purchases. Following widespread backlash from EU regulators, developers, and advocacy groups like the Coalition for App Fairness, Apple reversed its decision on March 1, 2024, just days before the 17.4 compliance deadline of March 6. In an update to its developer documentation, Apple confirmed it would retain support for WebKit-based web apps in the , maintaining their pre-iOS 17.4 functionality rather than disabling the add-to-home-screen feature. The firm attributed the initial plan to DMA complexities but noted the reversal preserved existing capabilities amid ongoing evaluation of broader browser engine allowances. iOS 17.4 launched on March 7, 2024, incorporating the reversal, which allowed EU users to continue installing WebKit-powered PWAs directly to the via without interruption. However, Apple emphasized that non-WebKit web apps would not be supported, and future DMA evolutions could prompt further adjustments, reflecting the company's balancing of regulatory mandates with its ecosystem controls. Critics, including web standards advocates, viewed the backtrack as a concession to pressure rather than a principled shift, given Apple's prior resistance to PWA parity with native apps to safeguard revenue streams.

Broader Implications for Innovation and User Protection

The European Union's (DMA), enforced through changes in 17.4 released on March 7, 2024, mandated allowances for alternative app distribution methods, including and third-party app stores, exclusively for users. These alterations aimed to enhance competition but introduced trade-offs between fostering app ecosystem diversity and maintaining established security protocols. Apple's closed model, which reviews all apps for compliance, has empirically correlated with lower prevalence on devices compared to more open systems; data from 2023–2024 indicates Android devices face infection rates up to 50 times higher than due to fragmented distribution channels. Proponents of the DMA argue that permitting alternative marketplaces could accelerate innovation by reducing Apple's gatekeeping, enabling developers to bypass 30% commissions and experiment with novel payment systems or browser engines. However, Apple contends that such fragmentation diverts resources from universal feature development—evidenced by delayed rollouts of capabilities like advanced Apple features to users—and erodes the incentives for high-quality curation that underpin iOS's rapid iteration cycles. Security analyses highlight causal risks: circumvents centralized vetting, potentially elevating fraud and vectors, as alternative stores lack equivalent notarization processes, mirroring Android's higher vulnerability to exploits where 92% of targeted the platform in 2023. A specific illustration emerged with progressive web apps (PWAs), where Apple initially planned to disable installation in the under 17.4 to align with DMA requirements, citing uniform compliance challenges, but reversed this on March 1, 2024, following developer and user feedback to preserve functionality built on . This adjustment underscores broader tensions: while reversals mitigate immediate innovation barriers, ongoing DMA interoperability mandates could compel deeper architectural compromises, potentially compromising the cohesive that has driven adoption. Empirical outcomes remain under scrutiny, with early reports noting no significant uptick in -specific threats post- 17.4, yet long-term data may reveal whether relaxed controls enhance or undermine protection against evolving threats like state-sponsored . In essence, these iOS 17-era shifts reflect a regulatory push prioritizing over platform , with Apple's historically demonstrating that stringent controls—rather than openness—have yielded superior user safeguards and sustained through controlled evolution, as opposed to the dilution observed in less gated environments.

Known Issues and Criticisms

Battery Drain and Performance Glitches

Following the release of iOS 17 on September 18, 2023, brief overheating or slightly increased battery drain may occur initially, especially on older devices; these effects typically resolve after a few days as the system performs optimizations such as reindexing and recalibration. On older models, post-update heating results from background tasks like reindexing, new visual effects, and resource-intensive features straining less efficient processors; the iPhone 11, 12, and 13 series are particularly prone during charging, camera use, or gaming, potentially triggering thermal throttling that worsens lag, though symptoms ease after initial stabilization. A significant number of users reported accelerated battery drain compared to previous versions, with complaints surfacing prominently on social media platforms like X (formerly Twitter) and forums such as and Apple Discussions. Users described batteries depleting 20-50% faster during typical activities like browsing or standby, often accompanied by increased device warmth, particularly on models like the and older XR/XS series. These issues were not universal but appeared more pronounced on devices with aging batteries or those not recently updated, suggesting contributing factors like unoptimized background processes rather than a systemic flaw across all hardware. Apple attributed much of the drain to temporary post-update activities, including Spotlight search reindexing, app library rebuilding, and model recalibration, which can consume substantial power for 2-5 days before stabilizing. Official guidance emphasized monitoring via Settings > Battery for high-drain apps and disabling features like background app refresh or location services if needed, while noting that full optimization typically resolves the problem without intervention. Persistent reports, however, indicated that some users experienced ongoing drain even after a week, potentially exacerbated by third-party apps not yet adapted to iOS 17's APIs or misconfigured settings like on compatible models.
