Opening Main App from Screen Time Configuration Action Extension
I'm working on an app for iOS that will help people get tasks done. Within the app, we use a ManagedSettingsStore to let the user setup distracting apps. When the user opens any of those apps while it is being shielded, our ShieldConfiguration target opens and displays a screen that we configure with the description of the task they are supposed to do. On the bottom of the view, there are two buttons, one to start the task, and another to dismiss and return to their home screen. I want to have the button that starts the task open up the main application and deeplink to the focus view with the task that they started. Currently, the only thing that we can tell the system to do is via a ShieldActionResponse which is an enum with 3 cases: none, close, or defer. None of these three allow us to open the main application. I have found no workarounds that allow us to do it either. I've tried creating a custom URL scheme and calling UIApplication.shared.open(url), but there is no shared application available within the action extension. I have tried using a NSExtensionContext to open a url, but that does not work either. I have even tried starting a live activity to show the user what task they are working on and have a live timer, but that does not work either. I know it is technically possible, because an app I downloaded does it perfectly. The app is called "Ascent: Screen Time Control". Is there some sort of extension I am missing, or entitlement I have not requested? Any help would be very appreciated.

Our customer's events on calendar are disappeared
Our app provides a calendar that integrates with the default calendar app. Specifically, we use iOS EventKit to perform CRUD operations on calendar data. Recently, we have received reports from users that all of their events have disappeared. However, after reviewing our implementation and logs, we have not been able to identify the cause. Some users have also reported that all data in their default calendar app has disappeared as well. Does anyone have any idea what might be causing this? To delete an event within our app, users must press the delete button and then confirm the deletion in a dialog. Additionally, it is not possible to delete more than two events at once. We've seen many people in the community discussing a bug where calendar events disappear after updating to iOS 18. If you have any information about when or why this happens, we'd appreciate it if you could share your insights.

The menu can't be shown in background process in MacOS 26(beta)
After I upgraded to MacOS 26(beta), my program caused the system to pop up a window as shown in the following picture. My application is a process with only a tray icon. I found that my tray icon is not displayed in the current version, even though I clicked the "Always Allow" button. Here are my questions: 1.Will this related feature remain consistent in the official release? 2.How can I create a cmd process that only displays a system tray icon (no main window) like Alfred?

Default dialer abilities & limitations
I've been trying to understand what kind of UX is available if my app is using the default-dialer capability. I have found https://developer.apple.com/documentation/livecommunicationkit/preparing-your-app-to-be-the-default-dialer-app and I am in the EU. On android I built the UX I want and it's quite neat, so now I'm trying to work. out what I can get on iOS. Because the product is kind of worthless with just android. I have built a simple dialer ux with a numberpad, contact lookup etc. Then when the user presses the Call button does it have to pop up the system prompt "Call number"? Does it have to swap over to the system ui for the actual call? So there's no way to show information about the call, during the call? Or am I using the frameworks incorrectly? I am very new to iOS development. TrueCaller and others show validation, but as I understand it they pre-fetch all the data, I can't do that.

Confused by new Swift XPC API's xpc_listener_t and xpc_session_t types
Hey! I'm trying to create an XPC messaging feature between my daemon and main application. I'm trying to use the new Swift low-level API available from macOS 14.0. The documentation is extremely confusing when looking at it from Swift: The xpc_listener_t type Seems to be something I shouldn't use in the Swift API, and would rather have to use XPCListener. Also, it appears to have no public API other than the xpc_listener_set_peer_code_signing_requirement function. Which would make it impossible to create this type. However, when going into xpc.h, one can see that there is an API in fact: API_AVAILABLE(macos(14.0), macCatalyst(17.0)) API_UNAVAILABLE(ios, tvos, watchos) XPC_EXPORT XPC_SWIFT_NOEXPORT XPC_RETURNS_RETAINED XPC_WARN_RESULT xpc_listener_t _Nullable xpc_listener_create(const char * service, dispatch_queue_t _Nullable target_queue, xpc_listener_create_flags_t flags, xpc_listener_incoming_session_handler_t incoming_session_handler, xpc_rich_error_t _Nullable * _Nullable error_out); which is a very unusual declaration - the first parameter for example shows up as Int8 type in Swift. Not to mention I haven't been able to create the next parameter, xpc_listener_create_flags_t at all, even though it seems to be a UInt64-based flag based on the C declaration, but passing UInt64(0) throws a compiler error. It really seems like something I shouldn't use from Swift. But then again, the extremely important security-related API mentioned above, xpc_listener_set_peer_code_signing_requirement can only take an xpc_listener_t object as a parameter, not an XPCListener type. There seems to be no conversion available between the two. However the documentation in the XPC framework seems to be telling the story of these two types being very equal, because of the following: The xpc_session_t type seemingly again has only deprecated methods mostly, the important one staying behind is xpc_session_set_peer_code_signing_requirement. However, this would again require the creation of an xpc_session_t object, for which in the XPC framework one will find declarations like: @available(macOS, introduced: 13.0, deprecated: 14.0, renamed: "XPCSession") @available(macCatalyst, introduced: 16.0, deprecated: 17.0, renamed: "XPCSession") @available(iOS, unavailable) @available(tvOS, unavailable) @available(watchOS, unavailable) public typealias xpc_session_t = OS_xpc_object plus basically all API of XPCSession being originally declared as xpc_session_* APIs and all of them having deprecated: 14.0, renamed: * marks. This is telling me xpc_session_t and XPCSession are in fact the same/same-ish. But again, there is seemingly no conversion between these two types. Which brings me to again being unable to create a code signing requirement for the XPCSession object. I've read some older forum posts, and I saw Apple Engineers admitting the code signing requirement APIs are missing from the new Swift APIs, however they seem to have been added in macOS 14.4 - although it appears to have been mistakenly added to the C-family functions, which have not been exposed to Swift correctly, because they still use the deprecated xpc_listener_t and xpc_session_t types. So my question is: what is going on here? :) Making XPC connections without a code signing requirement in 2025 seems like a no-go, so do I have to still stick with C - even though this new API seems to be focused on Swift?

Translation API not working without the Apple Translate app installed
Hello, My app depends on the Translation framework (iOS 17.4+), but I've found out that it doesn't work unless the Apple Translate app is installed on the device. After I've deleted Apple's translation app, I started getting the following errors: Optional(Foundation.Locale.Language(components: Foundation.Locale.Language.Components(languageCode: Optional(en), script: nil, region: Optional(GB)))) Optional(Foundation.Locale.Language(components: Foundation.Locale.Language.Components(languageCode: Optional(es), script: nil, region: Optional(ES)))) Error sending 1 paragraphs Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Failed to translate input 0; returning error: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Received unbridged NSError to API, converting to `.internalError`: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} TranslationError(cause: Translation.TranslationError.Cause.internalError, sourceLanguage: nil, targetLanguage: nil) This is an example from trying to translate text from English to Spanish. And I was receiving the error even though I have the dictionaries downloaded. Once I reinstalled Apple's Translate app, it started working again. This sadly means that users of my app must have the factory translation app installed, otherwise they won't be able to use my app. Some people choose to delete the factory apps. Why is the framework not available then? :(

Live Caller ID Lookup - Error on Refresh PIR Parameters
Hello. I've implemented the Live Caller ID Lookup feature in my app, but sometimes I get a weird error. When I call LiveCallerIDLookupManager.shared.refreshPIRParameters(...) from my app, it sometimes throws an error: Error Domain=com.apple.CipherML Code=1100 "Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSUnderlyingError=0x118f65740 {Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSErrorFailingURLKey=http://www.example.com/config}}} What does this error mean? And where did the example.com part come from? What should I do to get rid of this error? My Service URL is hardcoded in the Live Caller ID Lookup Extension of my app and it is definitely not example.com.

Live Lookup flow stuck at /issue/token-key-for-user-token endpoint
Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream <DER bytes> Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

A Summary of the WWDC25 Group Lab - watchOS (Part 1)
At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for watchOS (part 1). 1. I'm really excited about the new design system on all platforms. Liquid Glass is super cool. What do developers need to keep in mind when building for watchOS 26? To adopt the new design system, start with updating your app for watchOS 10 – If you have done so, your app will be mostly ready for watchOS 26. For more information, see Design and build apps for WatchOS 10. You can then look into Liquid Glass specific APIs to fine tune your app. This topic is covered in Adopting Liquid Glass. If you have SwiftUI views using any custom style, make sure they are still legible and fit with the new design system. 2. Something that really stood out to me were updates to the Smart Stack, with the system prioritizing Widgets when they're most relevant. Tell me more about these new opportunities for apps. Workout apps that record workouts using HealthKit may be automatically suggested on the watch face and appear in the Smart Stack without adding a widget. Relevant widgets are a great way to present information related to a date, location, point-of-interest type, sleep schedule, or fitness condition in the Smart Stack when it is relevant. Relevant widgets don't need to display a empty state view when they are not relevant. They are only shown in the Smart Stack when relevant. The watchOS 26 Design ToolKit in the Apple Design Resources includes a set of templates that you can use to layout your widgets. 3. Is the Wrist Flick gesture available to developers in the same way as Double Tap is? The system uses Wrist Flick to dismiss notifications and incoming calls, silence timers and alarms, or return to the watch face. There is no separate API for the Wrist Flick gesture. Apps that are using XCUIAutomation to make sure their user interface behaves as intended can use the XCUIDeviceHandGesture.flick to automate tests that verify that their app responds appropriately to the Wrist Flick gesture. For apps using automated testing, the XCUIDeviceHandGesture.doubleTap can be also be used to automate testing of the app with the Double Tap gesture. See XCUIDevice.perform(handGesture:) 4. Can HRV measurements be triggered on demand via API in watchOS? Guidelines or processes for enabling energy-intensive biometric sampling on development devices for IRB-approved research? You don’t have direct control on the sampling rate in watchOS. You can use HealthKit (HKQuantityTypeIdentifierHeartRateVariabilitySDNN, to be specific) to query the HRV data, once the system has sampled and persisted the data to HealthKit. If that doesn’t help, we suggest that you file a feedback report with your concrete use case for us to investigate. Specific to IRB-approved research using Apple Watch or its companion iPhone, you might want to look at this FAQ and SensorKit to see if they can be of any help. 5. What is the best advice for someone who is new to making a watchOS app that’s been on iOS and iPadOS? You can start with exploring the system experience features on watchOS, such as notifications, controls, and widgets, and getting familiar with the system spaces, like Smart Stack, watch face, and control center. Knowing the watchOS app design principles and practices is important as well. Design and build apps for WatchOS 10 is a great resource for this topic. SwiftUI is an amazing across-platform framework, and you will use it to create your watchOS app. If you're already using it, great! Keep in mind some watch-only constraints. Comparing to iPhone or iPad, Apple Watch has a limited battery and smaller screen size, which significantly impacts how people use your app and how your app works. 6. Was there any extension this year to the 7 day limit on querying Apple Health data on the watch? There is no change on the limit this year. You can get this official limit at runtime using earliestPermittedSampleDate. There are some exceptions, and so don't be surprised if you see some data types are retained longer. The companion iPhone holds the full set of the health data. If you need to access the health data that has been purged from the Apple Watch, consider doing it with your iOS app, and then passing the result to your watchOS app.

How to debug Quick Look Preview Extension
When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Unable to locate my stickers in message app after installed my app
My sticker app was rejected when I submitted it to App Store Connect. Reason: "We were unable to locate your stickers in message app after installed your app." When I checked on an iOS18 device, this was correct. However, my stickers is visible when I dragged the half-modal(like sheetPresentationController) part. I hope what I need to do to get the stickers to display initially. My code(Xcode16.2) class StickerViewController: MSStickerBrowserViewController { var stickers = [MSSticker]() override func viewDidLoad() { super.viewDidLoad() loadStickers() } override var stickerSize: MSStickerSize { get { return .small } } func loadStickers() { var imageSetPath = "en" for index in 1...20 { var strIndex = "" strIndex = "stmp" + String(index) + imageSetPath createSticker(assetLocation: "\(strIndex)", assetDescription: "\(strIndex)") } } func createSticker(assetLocation: String, assetDescription: String) { guard let path = Bundle.main.path(forResource: assetLocation, ofType: "png") else { return } let url = URL(fileURLWithPath: path) do { let sticker = try MSSticker(contentsOfFileURL: url, localizedDescription: assetDescription) stickers.append(sticker) } catch { print(error) } } } extension StickerViewController { override func numberOfStickers(in stickerBrowserView: MSStickerBrowserView) -> Int { return stickers.count } override func stickerBrowserView(_ stickerBrowserView: MSStickerBrowserView, stickerAt index: Int) -> MSSticker { return stickers[index] } }

Phonetic vs Pronunciation contacts fields and Siri
The contacts app has fields for Phonetic and Pronunciation. My app adds phonetic data to the phonetic field to help Siri better understand contacts stored in Greek, Cyrillic, or Georgian. However, using the phonetic field causes the sorting order of contacts to be messed up. For example, Greek B (beta) is represented as a phonetic sound of V, resulting in a completely incorrect sorting order. The pronunciation field doesn’t seem to affect the sorting order, but I’m not sure what it does or should do. My questions are: Do we understand the difference between phonetic and pronunciation, and how Siri actively uses them? If the phonetic field is the correct one to use, how can we raise a feature request with Apple to add an option to sort contacts based on phonetic fields or not? Here’s a test you can try: Create a new contact with the following details: First name: test Last name: test Phonetic first name: Billy Phonetic last name: Idol Ask Siri to show the contact Billy Idol. It will return the “test test” contact. Switch from the phonetic to the pronunciation fields. Now, Siri won’t find Billy Idol.

TipKit: Are tips marked "IgnoresDisplayFrequency" also ignored by display frequency?
Greetings, I have set up two tips in my app, and my app is configured with Tips.configure([.displayFrequency(.daily)]. Tip 1 is set up with no options. Tip 2 has the IgnoresDisplayFrequency(true) option set: var options: [Option] { MaxDisplayCount(3) // We want the user to see these because it's important. IgnoresDisplayFrequency(true) } This option works as expected, as far as I can tell, in terms of making sure that Tip 2 is shown even if I've already seen Tip 1 today. If I interact with my app such that Tip 1 is displayed, and I then interact with it such that Tip 2 should be displayed, Tip 2 shows immediately, even though a day hasn't passed. However, if I do this the other way around, so that Tip 2 is displayed first, and then I interact so that Tip 1 should be displayed, my expectation would be that Tip 1 is not displayed, because another tip has already been shown today. I expected that it would not be shown until the following day, since it is not configured to ignore the tip frequency. That's not what happens, though. Tip 1 is displayed right away, even though Tip 2 has just been shown. This makes me think that setting IgnoresDisplayFrequency on Tip 2 is causing it to also be ignored when considering whether other tips should be shown. I did try omitting IgnoresDisplayFrequency option, and then as expected, only one tip is shown on a day, no matter which one is shown first.

However the documentation in the XPC framework seems to be telling the story of these two types being very equal, because of the following: The xpc_session_t type seemingly again has only deprecated methods mostly, the important one staying behind is xpc_session_set_peer_code_signing_requirement. However, this would again require the creation of an xpc_session_t object, for which in the XPC framework one will find declarations like: @available(macOS, introduced: 13.0, deprecated: 14.0, renamed: "XPCSession") @available(macCatalyst, introduced: 16.0, deprecated: 17.0, renamed: "XPCSession") @available(iOS, unavailable) @available(tvOS, unavailable) @available(watchOS, unavailable) public typealias xpc_session_t = OS_xpc_object plus basically all API of XPCSession being originally declared as xpc_session_* APIs and all of them having deprecated: 14.0, renamed: * marks. This is telling me xpc_session_t and XPCSession are in fact the same/same-ish. But again, there is seemingly no conversion between these two types. Which brings me to again being unable to create a code signing requirement for the XPCSession object. I've read some older forum posts, and I saw Apple Engineers admitting the code signing requirement APIs are missing from the new Swift APIs, however they seem to have been added in macOS 14.4 - although it appears to have been mistakenly added to the C-family functions, which have not been exposed to Swift correctly, because they still use the deprecated xpc_listener_t and xpc_session_t types. So my question is: what is going on here? :) Making XPC connections without a code signing requirement in 2025 seems like a no-go, so do I have to still stick with C - even though this new API seems to be focused on Swift?

Translation API not working without the Apple Translate app installed
Hello, My app depends on the Translation framework (iOS 17.4+), but I've found out that it doesn't work unless the Apple Translate app is installed on the device. After I've deleted Apple's translation app, I started getting the following errors: Optional(Foundation.Locale.Language(components: Foundation.Locale.Language.Components(languageCode: Optional(en), script: nil, region: Optional(GB)))) Optional(Foundation.Locale.Language(components: Foundation.Locale.Language.Components(languageCode: Optional(es), script: nil, region: Optional(ES)))) Error sending 1 paragraphs Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Failed to translate input 0; returning error: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} Received unbridged NSError to API, converting to `.internalError`: Error Domain=TranslationErrorDomain Code=16 "Translation failed" UserInfo={NSLocalizedDescription=Translation failed, NSLocalizedFailureReason=Offline models not available for language pair} TranslationError(cause: Translation.TranslationError.Cause.internalError, sourceLanguage: nil, targetLanguage: nil) This is an example from trying to translate text from English to Spanish. And I was receiving the error even though I have the dictionaries downloaded. Once I reinstalled Apple's Translate app, it started working again. This sadly means that users of my app must have the factory translation app installed, otherwise they won't be able to use my app. Some people choose to delete the factory apps. Why is the framework not available then? :(

Live Caller ID Lookup - Error on Refresh PIR Parameters
Hello. I've implemented the Live Caller ID Lookup feature in my app, but sometimes I get a weird error. When I call LiveCallerIDLookupManager.shared.refreshPIRParameters(...) from my app, it sometimes throws an error: Error Domain=com.apple.CipherML Code=1100 "Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSUnderlyingError=0x118f65740 {Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSErrorFailingURLKey=http://www.example.com/config}}} What does this error mean? And where did the example.com part come from? What should I do to get rid of this error? My Service URL is hardcoded in the Live Caller ID Lookup Extension of my app and it is definitely not example.com.

Live Lookup flow stuck at /issue/token-key-for-user-token endpoint
Hi Apple engineering team, I’m trying to integrate the new Live Caller ID Lookup (PIR) on iOS using your pir-service-example code as well as a custom mock server in Vapor, but the extension never advances past the /issue/token-key-for-user-token step. I’ve tried both: 1. Official Example Cloned https://github.com/apple/pir-service-example Ran PIRService locally Confirmed that GET /.well-known/private-token-issuer-directory → 200 GET /issue/token-key-for-user-token → 200 (DER bytes, correct SPKI) No POST /issue ever fires 2. Mock Server (Vapor) Implemented all five endpoints (/config, /.well-known/private-token-issuer-directory, /issue/token-key-for-user-token, /issue, /queries) Verified with curl and openssl asn1parse that: GET /.well-known/private-token-issuer-directory Content-Type: application/private-token-issuer-directory { "issuer-request-uri":"https://…/issue", "token-keys":[…] } GET /issue/token-key-for-user-token Content-Type: application/octet-stream <DER bytes> Added Cache-Control: public, max-age=3600 on directory and SPKI Stubbed POST /issue to always return { "token": "" } Still no POST /issue request from the extension Reproduction Steps Install and enable a Live Lookup extension pointing to my server. Trigger an incoming call on device. Watch server logs—only see the two GETs, never /issue or /queries. Expected Behavior After fetching the SPKI DER, the framework should issue a POST /issue call (Privacy Pass flow) and then POST /queries. Observed Behavior Stuck in an infinite loop of: GET /.well-known/private-token-issuer-directory GET /issue/token-key-for-user-token (repeat…) No progression to the /issue or /queries endpoints. What I’ve Tried Verified JSON kebab-case and headers exactly match examples Confirmed SPKI DER is valid via openssl asn1parse Added Cache-Control headers Tested on real device, localhost url, and ngrok public URL Mocked a valid-looking token response Could you advise what additional requirement or format detail I’m missing that prevents from advancing past /issue/token-key-for-user-token? These are the main files: LiveLookupExtension.swift routes.swift service-config.json Thanks in advance!

A Summary of the WWDC25 Group Lab - watchOS (Part 1)
At WWDC25 we launched a new type of Lab event for the developer community - Group Labs. A Group Lab is a panel Q&A designed for a large audience of developers. Group Labs are a unique opportunity for the community to submit questions directly to a panel of Apple engineers and designers. Here are the highlights from the WWDC25 Group Lab for watchOS (part 1). 1. I'm really excited about the new design system on all platforms. Liquid Glass is super cool. What do developers need to keep in mind when building for watchOS 26? To adopt the new design system, start with updating your app for watchOS 10 – If you have done so, your app will be mostly ready for watchOS 26. For more information, see Design and build apps for WatchOS 10. You can then look into Liquid Glass specific APIs to fine tune your app. This topic is covered in Adopting Liquid Glass. If you have SwiftUI views using any custom style, make sure they are still legible and fit with the new design system. 2. Something that really stood out to me were updates to the Smart Stack, with the system prioritizing Widgets when they're most relevant. Tell me more about these new opportunities for apps. Workout apps that record workouts using HealthKit may be automatically suggested on the watch face and appear in the Smart Stack without adding a widget. Relevant widgets are a great way to present information related to a date, location, point-of-interest type, sleep schedule, or fitness condition in the Smart Stack when it is relevant. Relevant widgets don't need to display a empty state view when they are not relevant. They are only shown in the Smart Stack when relevant. The watchOS 26 Design ToolKit in the Apple Design Resources includes a set of templates that you can use to layout your widgets. 3. Is the Wrist Flick gesture available to developers in the same way as Double Tap is? The system uses Wrist Flick to dismiss notifications and incoming calls, silence timers and alarms, or return to the watch face. There is no separate API for the Wrist Flick gesture. Apps that are using XCUIAutomation to make sure their user interface behaves as intended can use the XCUIDeviceHandGesture.flick to automate tests that verify that their app responds appropriately to the Wrist Flick gesture. For apps using automated testing, the XCUIDeviceHandGesture.doubleTap can be also be used to automate testing of the app with the Double Tap gesture. See XCUIDevice.perform(handGesture:) 4. Can HRV measurements be triggered on demand via API in watchOS? Guidelines or processes for enabling energy-intensive biometric sampling on development devices for IRB-approved research? You don’t have direct control on the sampling rate in watchOS. You can use HealthKit (HKQuantityTypeIdentifierHeartRateVariabilitySDNN, to be specific) to query the HRV data, once the system has sampled and persisted the data to HealthKit. If that doesn’t help, we suggest that you file a feedback report with your concrete use case for us to investigate. Specific to IRB-approved research using Apple Watch or its companion iPhone, you might want to look at this FAQ and SensorKit to see if they can be of any help. 5. What is the best advice for someone who is new to making a watchOS app that’s been on iOS and iPadOS? You can start with exploring the system experience features on watchOS, such as notifications, controls, and widgets, and getting familiar with the system spaces, like Smart Stack, watch face, and control center. Knowing the watchOS app design principles and practices is important as well. Design and build apps for WatchOS 10 is a great resource for this topic. SwiftUI is an amazing across-platform framework, and you will use it to create your watchOS app. If you're already using it, great! Keep in mind some watch-only constraints. Comparing to iPhone or iPad, Apple Watch has a limited battery and smaller screen size, which significantly impacts how people use your app and how your app works. 6. Was there any extension this year to the 7 day limit on querying Apple Health data on the watch? There is no change on the limit this year. You can get this official limit at runtime using earliestPermittedSampleDate. There are some exceptions, and so don't be surprised if you see some data types are retained longer. The companion iPhone holds the full set of the health data. If you need to access the health data that has been purged from the Apple Watch, consider doing it with your iOS app, and then passing the result to your watchOS app.

How to debug Quick Look Preview Extension
When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Unable to locate my stickers in message app after installed my app
My sticker app was rejected when I submitted it to App Store Connect. Reason: "We were unable to locate your stickers in message app after installed your app." When I checked on an iOS18 device, this was correct. However, my stickers is visible when I dragged the half-modal(like sheetPresentationController) part. I hope what I need to do to get the stickers to display initially. My code(Xcode16.2) class StickerViewController: MSStickerBrowserViewController { var stickers = [MSSticker]() override func viewDidLoad() { super.viewDidLoad() loadStickers() } override var stickerSize: MSStickerSize { get { return .small } } func loadStickers() { var imageSetPath = "en" for index in 1...20 { var strIndex = "" strIndex = "stmp" + String(index) + imageSetPath createSticker(assetLocation: "\(strIndex)", assetDescription: "\(strIndex)") } } func createSticker(assetLocation: String, assetDescription: String) { guard let path = Bundle.main.path(forResource: assetLocation, ofType: "png") else { return } let url = URL(fileURLWithPath: path) do { let sticker = try MSSticker(contentsOfFileURL: url, localizedDescription: assetDescription) stickers.append(sticker) } catch { print(error) } } } extension StickerViewController { override func numberOfStickers(in stickerBrowserView: MSStickerBrowserView) -> Int { return stickers.count } override func stickerBrowserView(_ stickerBrowserView: MSStickerBrowserView, stickerAt index: Int) -> MSSticker { return stickers[index] } }

Phonetic vs Pronunciation contacts fields and Siri
The contacts app has fields for Phonetic and Pronunciation. My app adds phonetic data to the phonetic field to help Siri better understand contacts stored in Greek, Cyrillic, or Georgian. However, using the phonetic field causes the sorting order of contacts to be messed up. For example, Greek B (beta) is represented as a phonetic sound of V, resulting in a completely incorrect sorting order. The pronunciation field doesn’t seem to affect the sorting order, but I’m not sure what it does or should do. My questions are: Do we understand the difference between phonetic and pronunciation, and how Siri actively uses them? If the phonetic field is the correct one to use, how can we raise a feature request with Apple to add an option to sort contacts based on phonetic fields or not? Here’s a test you can try: Create a new contact with the following details: First name: test Last name: test Phonetic first name: Billy Phonetic last name: Idol Ask Siri to show the contact Billy Idol. It will return the “test test” contact. Switch from the phonetic to the pronunciation fields. Now, Siri won’t find Billy Idol.

TipKit: Are tips marked "IgnoresDisplayFrequency" also ignored by display frequency?
Greetings, I have set up two tips in my app, and my app is configured with Tips.configure([.displayFrequency(.daily)]. Tip 1 is set up with no options. Tip 2 has the IgnoresDisplayFrequency(true) option set: var options: [Option] { MaxDisplayCount(3) // We want the user to see these because it's important. IgnoresDisplayFrequency(true) } This option works as expected, as far as I can tell, in terms of making sure that Tip 2 is shown even if I've already seen Tip 1 today. If I interact with my app such that Tip 1 is displayed, and I then interact with it such that Tip 2 should be displayed, Tip 2 shows immediately, even though a day hasn't passed. However, if I do this the other way around, so that Tip 2 is displayed first, and then I interact so that Tip 1 should be displayed, my expectation would be that Tip 1 is not displayed, because another tip has already been shown today. I expected that it would not be shown until the following day, since it is not configured to ignore the tip frequency. That's not what happens, though. Tip 1 is displayed right away, even though Tip 2 has just been shown. This makes me think that setting IgnoresDisplayFrequency on Tip 2 is causing it to also be ignored when considering whether other tips should be shown. I did try omitting IgnoresDisplayFrequency option, and then as expected, only one tip is shown on a day, no matter which one is shown first.
