Does Contact Provider supports Localize when ask Permission
When I call https://developer.apple.com/documentation/contactprovider/contactprovidermanager/enable() to request to use Contact Provider, I received a dialog with message like this "App Name would like to add its contacts as its own list. Contacts added this way can be removed from settings". I would like to support this message in Japanese or other languages. Is it possible?

Open UIViewController when QR Code is scanned
Hi developers, I have a question if it is possible to open in my application not main window but a specific ViewController, when application is installed but not running. When the application is running in background and I scan QR code, then specific ViewController is opened over SceneDelegate and method 'userActivity'. But this does not work when the application is only installed, but not running. The Appstore link is here: https://apps.apple.com/us/app/don%C3%A1tor/id6473955033

Is MetricKit automatically on all devices?
Hello Apple, I am trying to get information such as crash context whenever a user encounters a situation where the app is killed. I was wondering if the tool MetricKit is available to all users or is this a feature to those who has opted into it. I am aware that the whenever someone gets a new device or in settings, an option will appear that'll have users decide whether or not to have Apple receive data analytics during certain events on their device. Does this have any effect on whether some users may not have MetricKit? Overall, we are attempting to use MetricKit to better analyze performance of our app. It would be inefficient for us, if the population of users using MetricKit is only those who have opted into it. Thanks, dmaliro

For the iOS/Xcode age range validation, what is an invalidRequest error?
One of the responses to a call to AgeRangeService.shared.requestAgeRange is AgeRangeService.Error.invalidRequest. This has no documentation. What on earth is an invalid request - I mean the app just calls the API, there's no parameters supplied or anything, how can the request ever be invalid? If the app calls AgeRangeService.shared.requestAgeRange and gets this as a response then what is the app supposed to do with that?

How to open up an extension point to a third-party app (extension)
According to the documentation, using Scope(restriction: .none) can expose the extension point to third-party app extensions. Below is my implementation, which ultimately results in an error. Code for declaring the extension point: @available(iOS 26.0, *) extension AppExtensionPoint { @Definition static var priceExtension: AppExtensionPoint { Name("priceExtension") UserInterface(false) Scope(restriction: .none) } } Code for locating the extension point: monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .priceExtension) When executing the code to locate the extension point, the following error occurs: However, in practice, I found that declaring the extension point in this way results in an error when trying to locate it: Error Domain=com.apple.extensionKit.errorDomain Code=19 "Failed to add observer" UserInfo={NSLocalizedDescription=Failed to add observer}

iMessages Deeplink App Switching for iOS 26.0
Ok so for some background, our app has a keyboard extension where we run a dictation service. Due to iOS limitations, this requires the user to press a button on the keyboard which will then bring the user to our app to activate an audio session. Once the audio session has been activated, it takes the user back to the original app it came from to continue using the keyboard + dictation service. The problem we're running into involves iOS 26.0 and the iMessages app. Whenever our app tries to switch back to the iMessages app using Deep Link (specifically the messages:// URL), the iMessages app opens up a new message compose sheet. This compose sheet replaces the view or message thread that the user was previously looking at which we don't want. This behavior appears to be only happening in iOS 26 and not in any of the previous iOS versions (tested up to iOS 18.6). We know that it should be possible to bring the user back to the messages app without opening up this new compose sheet, because similar apps do the same thing and these apps have been verified to work on iOS 26. We've tried also using the sms:// URL but that always opens a new message compose sheet regardless of whether or not it's iOS 26.0.

Screen sharing application - URGENT question
There are different kinds of screen-sharing applications, all using different APIs. The API used by AnyDesk, for example, or TeamViewer, which doesn't require light signals. I wonder if this is more appropriate for a corporate application, i.e. MDM, A screen-sharing application could be created and validated by Apple to display no light signals, and which could access the user's screen whenever the person wanted to after an initial acceptance? In other words, the user accepts to share his screen once, but won't be notified to accept the next time. Or is this impossible on iOS? I'd be honored to have some answers

DeviceActivityReport inconsistencies
Hello, I want to echo the DeviceActivityReport "concurrency" problems flagged in https://developer.apple.com/forums/thread/720549, and ask a related question. (Thanks to Kmart and other Apple dev support folks who have been monitoring these forums and responding diligently.) I would like to display daily and weekly stats in the same view, broken down by specific apps (as in the native Screen Time). However, instantiating multiple DeviceActivityReport objects with different filters and/or different contexts leads to confusion, where the two views will incorrectly and intermittently swap data or duplicate data where it shouldn't (seemingly upon some interval when the extension provides fresh data). There isn't documentation on how to display multiple reports at once. Is the idea that logic for multiple reports should be embedded within the extension itself in the makeConfiguration() function and there should only be a single DeviceActivityReport in the main App, or is this a bug? Even with a single DeviceActivityReport, I run into inconsistencies where the View provided by the extension takes multiple seconds to load or fails to load altogether. The behavior seems random...I will build the application with the same code multiple times and see different behavior each time. Finally, a plug for better support in the Simulator for the entire set of Screen Time APIs. Thanks!

iOS app crash when both .backgroundTask() and .scenePhase in App file
I've been having trouble with .backgroundTask(.appRefresh()) causing an intermittent crash when my app is launched. When the crash happens, the app flashes a darkened screen with the home screen device information (time-of-day, battery life, etc) weirdly pivoted landscape and right-justified. This screen shows for a split-second, disappears, and the app does NOT launch. Re-tapping the app icon will often re-launch the app without incident. After much trouble-shooting, I've discovered that commenting out EITHER @Environment(\.scenePhase) private var phase or the .backgroundTask(.appRefresh()) {} code eliminates the crash, so it's somehow caused by having both present at the same time. As you can see in the example below, it's not even necessary to actually use .scenePhase or .backgroundTask to run any other code in order to create the crash. The following minimal reproducible example will create the crash on an actual device, although you may need to launch and quit the app in quick succession 10-20 times to see the crash. (I realize most users aren't likely to do that - sometimes the crash occurs in the actual app on the first launch. But it's an intermittent problem so may require a few testing rounds to appear.) In addition to the code shown here, I've added the "Background Modes" capability with "Background Fetch" to "Signing & Capabilities" and added the "UpdateBadge" task to "Info" as a "Permitted background task scheduler identifier". Any idea what could be causing the crash and how to prevent it? struct ToyBackgroundTasksApp: App { @Environment(\.scenePhase) private var phase var sharedModelContainer: ModelContainer = { let schema = Schema([ Item.self, ]) let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false) do { return try ModelContainer(for: schema, configurations: [modelConfiguration]) } catch { fatalError("Could not create ModelContainer: \(error)") } }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(sharedModelContainer) .backgroundTask(.appRefresh("UpdateBadge")) { print("background task") } } }

WeatherKit AuthService Error
I have an app that I configured correctly. Checked the WeatherKit for the App ID, and added the WeatherKit to the Entitlements, and verified the Bundle ID was correct. I am getting the following error: Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+38.97170000,-95.23530000> +/- 0.00m (speed -1.00 mps / course -1.00) @ 3/1/25, 8:34:24 AM Central Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" I then made a super simple app that has a hard coded CLLocation and makes the single API call to get the weather and that fails with the same error. This error is still happening after 12 - 48 hours after creating the AppID. I have dumped the contents of the Provisioning Profile for both apps and the Entitlement section looks correct for both. I am not sure what is configured incorrectly, or what steps I should take next.

Network devices may not be able to connect to Personal HotSpot.
Explanation of the issue When tethering is enabled and a wireless connection is established, there are instances where an IP address is not assigned. Steps to Reproduce the Issue (if possible) Enable iPhone tethering and connect wirelessly using 11ax. Expected Result The iPhone assigns an IP address, enabling network connectivity. Actual Result Observed DHCP negotiation failed. After attempting communication with the DHCP server via DHCP Discover, a DHCP Offer was returned from the iPhone. If this was missed, it would retry by performing another DHCP Discover. However, the iPhone does not issue a DHCP Offer no matter how many times it retries. The IP address is not assigned unless the wireless connection is disconnected and reconnected. If the initial Discover is missed, does this invalidate subsequent Offer retries? The above issue has been confirmed on iPhone 17 Pro and iPhone 16. It does not appear to occur on iPhone 15.

Question about App Clip Update Behavior
Hello, I would like to understand the update behavior for App Clips. Let's consider a scenario where a user has an App Clip on their device from a previous interaction. If I, as the developer, then publish a new version of the App Clip to the App Store, what is the expected behavior? My main questions are: Will the App Clip be automatically updated in the background? Or, is user action required to get the new version, for example, by deleting the old one and re-launching it from a Smart App Banner or QR code? Any information on this process would be greatly appreciated. Thank you.

Issue with CXSetTranslatingCallAction – "Couldn't communicate with a helper application" error
Hi Team, We are encountering issues while implementing the live translation feature in our VoIP application using CallKit on iOS 26.0. Specifically, we are attempting to use the CXSetTranslatingCallAction transaction to enable translation programmatically during an active call. However, executing this transaction results in the following error: "Couldn't communicate with a helper application." This occurs consistently when we attempt to trigger the translation setup without user interaction. We are seeking clarification on the following points: Is it possible to enable CallKit's live translation feature using CXSetTranslatingCallAction purely programmatically, without requiring the user to interact with the system-provided Call UI? What does the above error indicate in the context of CXSetTranslatingCallAction? Are there specific conditions, entitlements, or background service requirements that must be fulfilled to communicate with CallKit? Code snippet: let translationAction = CXSetTranslatingCallAction(call: callUUID, isTranslating: true, localLocale: Locale.init(identifier: "es-ES"), remoteLocale: Locale(identifier: "en-US")) let transaction = CXTransaction(action: translationAction) callController.request(transaction) We would deeply appreciate any guidance you can provide regarding the feasibility of our approach and how to address this error. Thank you for your support.

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?

Custom `DiscreteFormatStyle` in live activities
Hello, I'm trying to display some Duration in a live activity using a custom format, with the goal of displaying a match time (only minutes) as, e.g. 33', 45' (+2), etc. For that purpose, I'm using a TimeDataSource&lt;Duration&gt;, so that it also updates automatically given a starting point. I've implemented my custom FormatStyle, trying to somehow mimic the existing UnitsFormatStyle (which perfectly works with live activities) but just changing the format. I've added conformance to DiscreteFormatStyle, and code-wise everything seems to be ok (if I've understood things correctly). It compiles and it even works as expected in a playground. However, when trying to use it within the live activity, I'm getting these cryptic errors in the Console.app, and the live activity just turns into a view with placeholders Failed to fetch view from archive at index 12: SwiftUI.AnyCodable&lt;SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement&gt;.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG") [624AEC37-13D9-4927-9F41-C3092B61E214] Failed to return view entry from archive for view model with tag listItem with error: SwiftUI.AnyCodable&lt;SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement&gt;.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG") Are there any limitations when it comes to live activities and these custom formatters? This whole error doesn't make sense, since I'm only aiming to update every minute, which should just be fine, the same thing I get with the UnitsFormatStyle. For reference, this is my playground, which just works as expected: import Foundation import SwiftUI import PlaygroundSupport extension Duration { struct MatchFormatStyle: DiscreteFormatStyle, Sendable { let periodLength: Int let overtime: Int func format(_ value: Duration) -&gt; String { let (seconds, _): (Int64, Int64) = value.components let minutes: Int = Int(seconds) / 60 let current: Int = periodLength + minutes + overtime if current &gt; periodLength { return "\(periodLength)' (+\(current - periodLength))" } else { return "\(current)'" } } func discreteInput(before input: Duration) -&gt; Duration? { let (seconds, _): (Int64, Int64) = input.components let minutes: Int64 = seconds / 60 - 1 return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero) } func discreteInput(after input: Duration) -&gt; Duration? { let (seconds, _): (Int64, Int64) = input.components let minutes: Int64 = seconds / 60 + 1 return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero) } } } extension FormatStyle where Self == Duration.MatchFormatStyle { static func matchTime(currentTime: Int, periodLength: Int) -&gt; Duration.MatchFormatStyle { return Duration.MatchFormatStyle(periodLength: periodLength, overtime: max(currentTime - periodLength, .zero)) } } extension TimeDataSource&lt;Date&gt; { static func matchDuration(for currentTime: Int, periodLength: Int) -&gt; TimeDataSource&lt;Duration&gt; { let minutesAhead: Double = Double(max(periodLength - currentTime + 1, .zero)) return TimeDataSource&lt;Date&gt;.durationOffset(to: Date.now.addingTimeInterval(minutesAhead * 60)) } } struct FooView: View { let currentTime: Int = 36 let periodLength: Int = 45 var body: some View { Text( TimeDataSource&lt;Date&gt;.matchDuration(for: currentTime, periodLength: periodLength), format: .matchTime(currentTime: currentTime, periodLength: periodLength) ) .frame(width: 400, height: 200) .font(.system(size: 50)) } } // Present the view controller in the Live View window PlaygroundPage.current.setLiveView(FooView()) Any hints or suggestions are welcome, many thanks in advance.
