WeatherKit request fail
Hello, I have an app on the App Store built around WeatherKit and it was working fine, up until this morning when I started seeing errors when using the app. When debugging using Xcode I see the familiar error Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" which, according to what I've read on the forums looks like an authentication error. Attaching a network debugger to the Simulator, I saw this error: This I have tried: Verify that WeatherKit is enabled on both Capabilities and App Services tabs on the Dev Portal. Toggle on/off this value and regenerate Provisioning Profiles Uninstall/reinstall Checking that I have API available calls. Nothing. If I create a new Bundle ID and sign with that, it works correctly. But this is not an option since that will force all my customers to download everything from scratch. I am getting emails from customers demanding money back and I can't figure out what has happened. The only thing I can think of, is that I started developing an Apple Watch app to complement the iOS app, but that was last week and everything was working fine.

Crashes on iOS 18.x
Starting with iOS 18.3, we are getting infrequent crash reports somehow related to web sockets. Are there any new caveats we should be aware of or is it just a CFNetwork bug?

QuickLook Thumbnailing returns stale macOS 26 folder icon
On macOS 26, I've run into a situation when a user “customizes” a folder icon with Finder by assigning/changing an SF Symbol or an emoji, QLThumbnailGenerator keeps returning the stale initially retrieved folder icon (no matter whether it had been customized or not) until my app quits. After the app is re-launched, the icon is correctly retrieved once again. let generator = QLThumbnailGenerator.shared let size: CGSize = CGSize(width: 64, height: 64) let request = QLThumbnailGenerator.Request(fileAt: url, size: size, scale: NSScreen.main!.backingScaleFactor, representationTypes: .icon) request.iconMode = true do { let thumb = try await generator.generateBestRepresentation(for: request) thumb.nsImage.size = size return thumb.nsImage } catch { print("generateThumbnail: \(error)") return nil } It seems like the QuickLook Thumbnailing cache does not invalidate automatically upon folder customization. Is there any way to manually invalidate the QuickLook Thumbnailing cache?

App Clip Experience Does Not Update Content After Initial Creation (Persistent Caching Issue)
Hi everyone, We’re running into a serious issue with App Clip Experience updates not propagating to devices, and I’m hoping someone here has encountered (or solved) this before. Problem Once an App Clip Experience is created and used on devices, subsequent updates made in App Store Connect do not reflect on any devices, even after a long period of time. We’ve tried: • Updating the App Clip Experience URL (adding utm parameters, for example, utm_source and scanning via QR code) • Modifying Experience metadata/content • Waiting several days (over a week) • Testing on multiple devices (including devices that never opened the App Clip before) Despite this, the App Clip continues to show the initially created content, while App Store Connect clearly shows the updated configuration. Important Details • We currently have ~1,300 App Clip Experiences created • All App Clips use the same App Clip Bundle ID • The content behind the URLs updates correctly on the website • Only the App Clip continues to show stale / initial data • Removing and re-invoking the App Clip on devices does not consistently fix the issue At this point, manual updates via App Store Connect appear to be completely ignored once the App Clip is “established.” Questions 1. Is there a known hard cache or CDN behavior on Apple’s side that prevents App Clip Experience updates from propagating? 2. Is there any way to invalidate or refresh an existing App Clip Experience? 3. Does having a large number of App Clip Experiences (~1300) affect update behavior or caching? 4. Is the recommended approach to treat App Clip Experience as immutable and handle all updates via backend / dynamic content only? Right now it feels like: App Clip Experience is effectively a one-time snapshot and not a live-updatable configuration. Any insights, confirmations, or official guidance would be greatly appreciated. Thanks in advance.

Universal links: Open in "MyApp" doesn't launch my app
I've a strange problem which is only occurring on 2 client devices. We have enabled Universal links, and have it fully tested and working. On one client device, the link never opens our app; but here's the strange thing: If I long-press on our link (in Messages), it gives a preview (as expected), and the context menu offers "Open in ", as well as "Open in Safari". Tapping on "Open in " does nothing. I've tried the following: Checked I could access the site-association file over https with no redirects Enabled developer mode and used universal link debug feature: pasted the same link - Developer mode says it will open the app. I've carried out the sysdiagnose; And there are entries in there for our app in swcutil_show.txt. Snipped below: Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: www.<mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: <mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- Service: applinks App ID: <my fully qualified app bundle id> App Version: 760.0 App PI: <LSPersistentIdentifier 0x6b8008930> { v = 0, t = 0x8, u = 0x45c, db = DC8D18A2-430D-4AD4-A5BE-B7A003CF9A6F, {length = 8, bytes = 0x5c04000000000000} } Domain: *.<mydomain>.com Patterns: {"/":"/cc/*"}, {"?":{"t":"*"},"/":"/md/"} User Approval: unspecified Site/Fmwk Approval: approved Flags: Last Checked: 2025-04-29 09:10:21 +0000 Next Check: 2025-05-04 08:42:50 +0000 -------------------------------------------------------------------------------- The version numbers match the installed version of my app I've tried running logging and just capturing logs before and after I press the "open in ", but there's nothing suspicious in there. And the kicker - it's only happening on a single device. No other devices are experiencing this.

Caller ID is truncated on IOS 18
We use call directory extension in one of our applications, we notice that call id is truncated on IOS 18. Example: "Grady GmbH" instead of "GRADY ARCHIE, PRICEWATERHOUSECOOPER GMBH" We notice also if we have calls in the history then the caller id is shown correctly. Issue only on IOS 18.

UserDefaults.didChangeNotification not firing
Hi, I'm currently working on an app made originally for iOS 15. On it, I add an observer on viewDidLoad function of my ViewController to listen for changes on the UserDefault values for connection settings. NotificationCenter.default.addObserver(self, selector: #selector(settingsChanged), name: UserDefaults.didChangeNotification, object: nil) Said values can only be modified on the app's section from System Settings. Thing is, up to iOS 17, the notification fired as expected, but starting from iOS 18, the notification doesn't seem to be sent by the OS. Is there anything I should change in my observer, or any other technique to listen for the describe event? Thanks in advance.

ApplicationTokens changing
We persist ApplicationTokens in a storage container that ShieldConfigurationExtension has access to. In rare, cases all the ApplicationTokens for a user seem to change. We know this because the Application parameter passed into configuration(shielding application: Application) -> ShieldConfiguration function has a Token that does not match (using == ) any of the ones we are persisting in storage. Interestingly, the persisted ones still work, so I don't believe storage has gotten corrupted or anything. We can use them to add or remove shields, we can use them to display labels of the apps they represent, etc. But they don’t match what’s passed into the ShieldConfiguration extension. If the user goes into the FamilyPicker at this point and selects an app of a token that we are already persisting, the FamilyPickerSelection will have a token matching the new one that is passed into ShieldConfigurationExtension, not the one we persisted when they last selected that app. This leads me to believe the tokens are updated/rotated in some cases. When and why does this happen, and how can we handle it gracefully?

Does Core Spotlight work with document-based apps?
I have a SwiftUI document-based app that for the sake of this discussion stores accounting information: chart of accounts, transactions, etc. Each document is backed by a SwiftData DB. I'd like to incorporate search into the app so that users can find transactions matching certain criteria, so I went to Core Spotlight. Indexing & search within the app seem to work well. The issue is that Spotlight APIs appear to be App based & not Document based. I can't find a way to separate Spotlight data by document. I've tried having each document maintain a UUID as a document-specific identifier and include the identifier in every CSSearchableItem. When performing a query I filter the results with CSUserQueryContext.filterQueries that filter by the document identifier. That works to limit results to the specific file for search operations. Index updates via CSSearchableIndexDelegate.reindex* methods seem to be App-centric. A user may have file #1 open, but the delegate is being asked to update CSSearchableItems for IDs in other files. Is there a proper way to use Spotlight for in-app search with a document-based app? Is there a way to keep Spotlight-indexed data local within the app & not make it available across the system? I.e. I'd like to search within the app only. System-level searches should not surface this data.

Safari Web Extensions & NSXPCConnection
I have a basic setup following WWDC 2020 on Safari Web Extensions and another one on XPC. The video even mentions that one can use UserDefaults or XPC to communicate with the host app. Here is my setup. macOS 15.2, Xcode 16.2 A macOS app (all targets sandboxed, with an app group) with 3 targets: SwiftUI Hello World web extension XPC Service The web extension itself works and can update UserDefaults, which can then be read by SwiftUI app - everything works by the book. The app can communicate to the XPC service via NSXPCConnection - again, everything works fine. The problem is that the web extension does not communicate with XPC, and this is what I need so that I can avoid using UserDefaults for larger and more complex payloads. Web Ext handler code: class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling { func beginRequest(with context: NSExtensionContext) { // Unpack the message from Safari Web Extension. let item = context.inputItems[0] as? NSExtensionItem let message = item?.userInfo?[SFExtensionMessageKey] // Update the value in UserDefaults. let defaults = UserDefaults(suiteName: "com.***.AppName.group") let messageDictionary = message as? [String: String] if messageDictionary?["message"] == "Word highlighted" { var currentValue = defaults?.integer(forKey: "WordHighlightedCount") ?? 0 currentValue += 1 defaults?.set(currentValue, forKey: "WordHighlightedCount") } let response = NSExtensionItem() response.userInfo = [ SFExtensionMessageKey: [ "Response to": message ] ] os_log(.default, "setting up XPC connection") let xpcConnection = NSXPCConnection(serviceName: "com.***.AppName.AppName-XPC-Service") xpcConnection.remoteObjectInterface = NSXPCInterface(with: AppName_XPC_ServiceProtocol.self) xpcConnection.resume() let service = xpcConnection.remoteObjectProxyWithErrorHandler { error in os_log(.default, "Received error: %{public}@", error as CVarArg) } as? AppName_XPC_ServiceProtocol service?.performCalculation(firstNumber: 23, secondNumber: 19) { result in NSLog("Result of calculation XPC is: \(result)") os_log(.default, "Result of calculation XPC is: \(result)") context.completeRequest(returningItems: [response], completionHandler: nil) } } } The error I'm getting: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.***.AppName.AppName-XPC-Service was invalidated: failed at lookup with error 3 - No such process." What am I missing?

Label with ApplicationToken cannot be styled?
Hi, I'm trying to make use of the Device Activity Labels where you supply an ApplicationToken. I can successfully get it to show the icon + title of the Application (twitter in my case) but I cannot get the styling to work. // Works .labelStyle(.iconOnly) .labelStyle(.titleOnly) .border(...) ![]("https://developer.apple.com/forums/content/attachment/9660b578-a36f-4d5a-ae18-653a207aa5ab" "title=Screenshot 2023-03-12 at 12.57.34 PM.png;width=1218;height=844") // Does NOT work .font(.largeTitle) .foregroundColor(.blue) I have checked the same style (or just modifiers) against a standard Label and they actually do work in the code below. // This is an application token. Some style not applied. Label(targetApp) .labelStyle(MyStyle()) // Showing the same style using a simple label. All styles correctly applied. Label("Twitter", systemImage: "video.square.fill") .labelStyle(MyStyle()) Is changing the font + color of the title for this Label(_ applicationToken:) supported?

iOS 26 Empty Stack Crash
When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes. However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues. Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes. app-2025-09-19-161044.ips.txt

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

How do I persist the Family Activity Picker?
I am currently building a screen time app and I am trying to figure out how to persist the family activity picker so that when my app closes and re-opens, the app selections in it are saved. I've successfully implemented core data and figured out how to store names of the selected apps in a list like this - Core Data addApp Function - func addApp(name: String, context: NSManagedObjectContext){ let newApp = AppToken(context: context) newApp.bundleIdentifier = name saveData(context: context) } Adding app selections to Core Data (after the family activity picker has updated the selection) - .onChange(of: model.selectionToDiscourage) { for i in model.selectionToDiscourage.applications { print(i) dataController.addApp(name:i.localizedDisplayName ?? "Temp", context: moc) } Printing saved selections in a list (bundleIdentifier is my attribute for my appToken entity, but I am just pulling the names here. For whatever reason all of them end up being Temp" as shown above anyway. In other words name:i.localizedDisplayName is not working and Temp is shown in the list for every app chosen) - if dataController.savedSelection.isEmpty { Text("No Apps Selected") .foregroundColor(.gray) } else { List(dataController.savedSelection, id: \.self) { app in Text(app.bundleIdentifier ?? "Unknown App") } .scrollContentBackground(.hidden) } So, when my app closes and reopens, the list of app names persists. Now, my issue is figuring out how to write back to selectionToDiscourage and loading the family activity picker with those saved apps. I have no idea if I should be doing this a different way and if using Core Data is overkill, but I cannot figure out how it's syntactically possible to write back to this family activity picker when the app reopens - .familyActivityPicker(isPresented: $isPresented, selection:$model.selectionToDiscourage) Thank you to whoever takes a look at this!!

Open Parent App From ShieldActionDelegate
Hello, I’m building an app that helps people spend less time on social media apps. For that, I make heavy use of Apple’s Screen Time APIs, such as ManagedSettings and FamilyControls. When an app is locked using a ShieldConfiguration, the user has to open my app in order to unlock it (e.g. enter a code). This is very cumbersome because no documented API exists to open the parent app (=my app) from the ShieldActionDelegate (also part of my app) when the user presses a button of the ShieldConfiguration. The ShieldActionDelegate callback just offers three options in its ShieldActionResponse: .none .defer .close .openParentApp is missing. We are working around this limitation by sending a local push notification that the user has to tap on. This has multiple drawbacks: It has to be ensured that notification permission has been granted. It has to be ensured that notifications can be delivered even while focus is enabled. Features such as Apple Intelligence notification summaries and notification prioritization can heavily delay delivering notifications and thus frustrate the user. Neither my users nor myself do understand why this is not possible in a smoother way, at least according to the documentation. There are 3rd party apps that have such functionality, they can directly open their own app from a button press in the Shield, see here: https://apps.apple.com/us/app/applocker-passcode-lock-apps/id1132845904 It would be great if Apple could level the playfield for all developers and document how this is achievable, because technically it clearly is. Thanks a lot and have a great day!

Contacts Provider Extension not removed from Contacts list after app uninstall on iOS 26
Hi, I’ve built an app that includes a Contacts Provider Extension (CPE). On iOS 18, I observed the expected behavior — when the main app is uninstalled, the corresponding CPE entry is also removed from the Contacts list. However, on iOS 26, this no longer happens. After uninstalling the app, the CPE remains visible and active in the Contacts list, even though the app is gone.

Changing Screen Time Passcode does not protect apps with Screen Time enabled
Hello, The purpose of "Screen Time Passcode" under Settings/Screen Time is to protect Screen Time preferences and it is asked every time the user updates Downtime, App Limits, Content & Privacy Restrictions and so on. But the private passcode is not requested if the user disables Screen Time for a particular app (only Face ID or phone passcode is requested, but not the private Screen Time passcode). I think this is a mistake, I think the purpose of a private Screen Time passcode is to protect all settings, including apps that use this API, right? Is there any solution to this? Thank you.
