Login issues on CloudKit Console
Hi everyone In the last 24 hours, I’ve been running into some issues with the CloudKit console. Most of the time, I‘ll get an error stating an error has caused this web page to stop working correctly. Reloading doesn’t fix the issue, nor does using different browsers: Today I’ve got another error, something along the lines of the Console not being able to fetch the teams I’m assigned to and an XHF error pop-up. Has anyone encountered the same issues? After trying multiple times, I’m able to reach my database but it’s a bit frustrating as it’s very unreliable this way. Thanks for your feedback! Dave

Stopping and Resuming Background Location Activity with CLLocationUpdates and CLBackgroundActivitySession
Hello, This is my first post in the forums, and I'm still learning my way with iOS Development and Swift. My apologies if the formatting is not correct, or If I'm making any mistakes. I'm currently trying to implement an iOS App where the device needs to share the location with my server via an API call. The use case is as follows: the server expects location updates to determine if a device is inside/outside a geofence. If the device is stationary, no locations need to be sent. If the device begins moving, regardless of whether the app is in foreground, background, or terminated, the app should resume posting locations to the server. I've decided to use the CLLocationUpdate.liveUpdates() stream, together with CLBackgroundActivitySession(). However, I have not been able to achieve the behavior successfully. My app either maintains the blue CLActivitySession indicator active, regardless of whether the phone is stationary or not, or kills the Indicator (and the background capability) and does not restore it when moving again. Below I've attached my latest code snippet (the indicator disappears and does not come back). // This method is called in the didFinishLaunchingWithOptions func startLocationUpdates(precise: Bool) { // Show the location permission pop up requestAuthorization() // Stop any previous sessions stopLocationUpdates() Task { do { // If we have the right authorization, we will launch the updates in the background // using CLBackgroundActivitySession if self.manager.authorizationStatus == .authorizedAlways { self.backgroundActivity = true } else { self.backgroundActivity = false self.backgroundSession?.invalidate() } // We will start collecting live location updates for try await update in CLLocationUpdate.liveUpdates() { // Handle deprecation let stationary = if #available(iOS 18.0, *) { update.stationary } else { update.isStationary } // If the update is identified as stationary, we will skip this update // and turn off background location updates if stationary { self.backgroundSession?.invalidate() continue } // if background activity is enabled, we restore the Background Activity Session if backgroundActivity == true { self.backgroundSession = CLBackgroundActivitySession() } guard let location = update.location else { continue } // Do POST with location to server } } catch { print("Could not start location updates") } } } I'm not sure why the code does not work as expected, and I believe I may be misunderstanding how the libraries Work. My understanding is that the liveUpdates stream is capable of emitting values, even if the app has gone to the background/terminated, thus why I'm trying to stop/resume the Background Activity using the "stationary" or "isStationary" attribute coming from the update. Is the behavior I'm trying to achieve possible? If so, I'm I using the right libraries for it? Is my implementation correct? And If not, what would be the recommended approach? Regards

PDFKit PDFPage.characterBounds(at:) returns incorrect coordinates iOS 18 beta 4
PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4. It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle) It breaks critical functionality that my app relies on. I have filed feedback (FB14843671). So far no changes in the latest betas. iOS release date is approaching fast! Anybody having the same issue? Any workaround available?

Does BGAppRefreshTask Run After a User Force-Quits the App? Seeking Official Clarification
I’m looking for an authoritative answer on how BGAppRefreshTask behaves after a user force-quits an app (swipes it away in the App Switcher). My app relies on early-morning background refresh to prepare and schedule notifications based on user-defined thresholds and weather forecasts. Behavior across devices seems inconsistent, however: sometimes a scheduled background refresh still runs, and other times it appears completely blocked. Apple’s documentation doesn’t clearly state what should happen, and developer discussions conflict. Could someone from Apple please clarify: Will a previously scheduled BGAppRefreshTask run after the user force-quits the app? If not, is there a recommended alternative for time-sensitive updates that must schedule user alerts? What is the expected system behavior regarding the predictability of background refresh after a force-quit? A definitive answer would help ensure the app aligns with intended system behavior. Thanks!

CarPlay not working on iOS 26 beta
Just wanted to check here to see if anyone else is running into the issue of CarPlay not working at all on iOS 26 Beta 1, even with the update on Friday. I plug my phone in (wired) and CarPlay never shows up. I've seen a Reddit thread where other folks are seeing the same thing.

Live Caller ID on iOS does not work - client requests not reaching backend
I'm reaching out to see if anyone else is experiencing issues with the Live Caller ID feature on iOS. We recently encountered a problem where the feature stopped working entirely. Here's a brief overview of the situation: We were monitoring test traffic on our backend and noticed everything came to a halt around 1:00 AM UTC on November 15th. After this time, any attempts to reach our backend through calls failed completely. I tested this across multiple devices running iOS 18.2 and iOS 18.0. I used both TestFlight builds and development builds via Xcode, which should communicate directly with our backend. I experienced the problem on our main application as well as a dedicated test app. To troubleshoot further, I even set up a local server on localhost and tried directing requests there, but the requests did not reach the local server when a call was received. Further debugging in Console.app revealed the following error: identity request returned error: Error Domain=com.apple.CipherML Code=400 "Error Domain=com.apple.CipherML Code=401 "Unable to request data by keywords batch: failed to fetch token issuer directory" However, when I manually tried to hit our server endpoint using curl, the request successfully reached the server: curl https://our_server/something hb_method=GET hb_uri=/something [Hummingbird] Request -- log on backend This suggests that while our backend is responsive, the requests from the iOS client side are simply not being initiated.

Direction data not available with U2 chip (iPhone 15 Pro and iPhone 16 Pro) when using Murata SR040/SR150 accessory
Hello, I am developing with the Nearby Interaction framework using third-party UWB accessories (Murata SR040/SR150). I observed a difference between U1-based and U2-based iPhones: iPhone 12 Pro (U1 chip) NINearbyObject.direction returns valid 3D vector (x, y, z). Distance and direction both work as expected. iPhone 15 Pro and iPhone 16 Pro (U2 chip) NINearbyObject.direction is always nil. Only distance is returned (around 0.35–0.40 m in my test). Effectively behaves as "distance-only mode". Environment: Hardware: iPhone 12 Pro, iPhone 15 Pro iOS version: 18.5 Accessory: Murata UWB SR040 / SR150 App: Using NINearbyAccessoryConfiguration with BLE-based discovery Info.plist includes NSNearbyInteractionUsageDescription Camera assistance was tested both ON and OFF Expectation: I expected the U2 chip to behave consistently with U1, i.e. provide direction vectors when possible. Instead, on iPhone 15 Pro, direction is always unavailable (nil) while distance is returned correctly. Questions: Is this an intentional limitation for U2 chip + third-party accessories? Is there a new requirement (e.g. certification, firmware update, capability flags) to enable direction on U2 devices? Could this be related to NIDeviceCapability or the new Extended Distance Measurement (EDM) mode in U2? Thanks in advance for any clarification.

Flutter library that basically makes a call every "x" minutes if the app is in the background.
Hi everyone, could you help us? We implemented a Flutter library that basically makes a call every x minutes if the app is in the background, but when I generate the version via TestFlight for testing, it doesn't work. Can you help us understand why? Below is a more detailed technical description. Apple Developer Technical Support Request Subject: BGTaskScheduler / Background Tasks Not Executing in TestFlight - Flutter App with workmanager Plugin Issue Summary Background tasks scheduled using BGTaskScheduler are not executing when the app is distributed via TestFlight. The same implementation works correctly when running the app locally via USB/Xcode debugging. We are developing a Flutter application that needs to perform periodic API calls when the app is in the background. We have followed all documentation and implemented the required configurations, but background tasks are not being executed in the TestFlight build. App Information Field Value App Version 3.1.15 (Build 311) iOS Minimum Deployment Target iOS 15.0 Framework Flutter Flutter SDK Version ^3.7.2 Technical Environment Flutter Dependencies (Background Task Related) Package Version Purpose workmanager ^0.9.0+3 Main background task scheduler (uses BGTaskScheduler on iOS 13+) flutter_background_service ^5.0.5 Background service management flutter_background_service_android ^6.2.4 Android-specific background service flutter_local_notifications ^19.4.2 Local notifications for background alerts timezone ^0.10.0 Timezone support for scheduling Other Relevant Flutter Dependencies Package Version firebase_core 4.0.0 firebase_messaging (via native Podfile) sfmc (Salesforce Marketing Cloud) ^9.0.0 geolocator ^14.0.0 permission_handler ^12.0.0+1 Info.plist Configuration We have added the following configurations to Info.plist: UIBackgroundModes <key>UIBackgroundModes</key> <array> <string>location</string> <string>remote-notification</string> <string>processing</string> </array> ### BGTaskSchedulerPermittedIdentifiers ```xml <key>BGTaskSchedulerPermittedIdentifiers</key> <array> <string>br.com.unidas.apprac.ios.workmanager.carrinho_api_task</string> <string>br.com.unidas.apprac.ios.workmanager</string> <string>be.tramckrijter.workmanager.BackgroundTask</string> </array> **Note:** We included multiple identifier formats as recommended by the `workmanager` Flutter plugin documentation: 1. `{bundleId}.ios.workmanager.{taskName}` - Custom task identifier 2. `{bundleId}.ios.workmanager` - Default workmanager identifier 3. `be.tramckrijter.workmanager.BackgroundTask` - Plugin's default identifier (as per plugin documentation) ## AppDelegate.swift Configuration We have configured the `AppDelegate.swift` with the following background processing setup: ```swift // In application(_:didFinishLaunchingWithOptions:) // Configuration to enable background processing via WorkManager // The "processing" mode in UIBackgroundModes allows WorkManager to use BGTaskScheduler (iOS 13+) // This is required to execute scheduled tasks in background (e.g., API calls) // Note: User still needs to have Background App Refresh enabled in iOS settings if UIApplication.shared.backgroundRefreshStatus == .available { // Allows iOS system to schedule background tasks with minimum interval UIApplication.shared.setMinimumBackgroundFetchInterval(UIApplication.backgroundFetchIntervalMinimum) } ## WorkManager Implementation (Dart/Flutter) ### Initialization ```dart /// Initializes WorkManager static Future<void> initialize() async { await Workmanager().initialize(callbackDispatcher, isInDebugMode: false); print('WorkManagerService: WorkManager initialized'); } ### Task Registration /// Schedules API execution after a specific delay ## Observed Behavior ### Works (Debug/USB Connection) - When running the app via Xcode/USB debugging - Background tasks are scheduled and executed as expected - API calls are made successfully when the app is backgrounded ### Does NOT Work (TestFlight) - When the app is distributed via TestFlight - Background tasks appear to be scheduled (no errors in code) - Tasks are **never executed** when the app is in background - We have tested with: - Background App Refresh enabled in iOS Settings - App used frequently - Device connected to WiFi and charging - Waited for extended periods (hours) ## Possible heart points 1. **Are there any additional configurations required for `BGTaskScheduler` to work in TestFlight/Production builds that are not required for debug builds?** 2. **Is the identifier format correct?** We are using: `br.com.unidas.apprac.ios.workmanager.carrinho_api_task` - Should it match exactly with the task name registered in code? 3. **Are there any known issues with Flutter's `workmanager` plugin and iOS BGTaskScheduler in production environments?** 4. **Is there any way to verify through logs or system diagnostics if the background tasks are being rejected by the system?** 5. **Could there be any conflict between our other background modes (`location`, `remote-notification`) and `processing`?** 6. **Does the Salesforce Marketing Cloud SDK (SFMC) interfere with BGTaskScheduler operations?** ## Additional Context - We have verified that `Background App Refresh` is enabled for our app in iOS Settings - The app has proper entitlements for push notifications and location services - Firebase, SFMC (Salesforce Marketing Cloud), and other SDKs are properly configured - The issue is **only** present in TestFlight builds, not in debug/USB-connected builds ## References - [Apple Documentation - BGTaskScheduler](https://developer.apple.com/documentation/backgroundtasks/bgtaskscheduler) - [Apple Documentation - Choosing Background Strategies](https://developer.apple.com/documentation/backgroundtasks/choosing_background_strategies_for_your_app) Thank you

Issues with Family Control API: App Blocking & Screen Time for Multiple Children
We are developing a parental control application in SwiftUI with features like app blocking and screen time management. We are using the Family Control API along with Apple Family Sharing, allowing parents to add multiple children to the family group. We have followed the apple documentation still we are facing following issues: App Blocking Issue: The family picker does not display each child's name separately or their apps individually. Instead, it shows all children's apps together, making it difficult to block apps for a specific child. Screen Time Data Issue: We receive the total screen time usage for all children combined rather than separate screen time data for each child. Syncing Delay: When a new child is added to the Family Sharing group, we are unsure how long it takes for their apps to sync and appear on the parent’s device.

Network Extension App for MacOS with 3 Extensions
Hi All, I am currently working on a Network Extension App for MacOS using 3 types of extensions provided by Apple's Network Extension Framework. Content Filter, App Proxy (Want to get/capture/log all HTTP/HTTPS traffic), DNS Proxy (Want to get/capture/log all DNS records). Later parse into human readable format. Is my selection of network extension types correct for the intended logs I need? I am able to run with one extension: Main App(Xcode Target1) <-> Content Filter Extension. Here there is a singleton class IPCConnection between App(ViewController.swift) which is working fine with NEMachServiceName from Info.plist of ContentFilter Extension(Xcode Target2) However, when I add an App Proxy extension as a new Xcode Target3, I think the App and extension's communication getting messed up and App not getting started/Crashing. Here, In the same Main App, I am adding new separate IPCConnection for this extension. Here is the project organization/folder structure. MyNetworkExtension ├──MyNetworkExtension(Xcode Target1) │ ├── AppDelegate.swift │ ├── Assets.xcassets │ ├── Info.plist │ ├── MyNetworkExtension.entitlement │ | ── Main │ |-----ViewController.swift │ └── Base.lproj │ └── Main.storyboard ├── ContentFilterExtension(Xcode Target2) │ ├── ContentFilterExtension.entitlement │ │ ├── FilterDataProvider.swift │ │ ├── Info.plist │ │ ├── IPCConnection.swift │ │ └── main.swift ├── AppProxyProviderExtension(Xcode Target3) │ ├── AppProxyProviderExtension.entitlement │ │ ├── AppProxyIPCConnection.swift │ │ ├── AppProxyProvider.swift │ │ ├── Info.plist │ │ └── main.swift └── Frameworks ├── libbsm.tbd └── NetworkExtension.framework Is my Approach for creating a single Network Extension App with Multiple extensions correct or is there any better approach of project organization that will make future modifications/working easier and makes the maintenance better? I want to keep the logic for each extension separate while having the same, single Main App that manages everything(installing, activating, managing identifiers, extensions, etc). What's the best approach to establish a Communication from MainApp to each extension separately, without affecting one another? Is it good idea to establish 3 separate IPC Connections(each is a singleton class) for each extension? Are there any suggestions you can provide that relates to my use case of capturing all the network traffic logs(including HTTP/HTTPS, DNS Records, etc), especially on App to Extension Communication, where my app unable to keep multiple IPC Connections and maintain them separately? I've been working on it for a while, and still unable to make the Network Extension App work with multiple extensions(each as a new Xcode target). Main App with single extension is working fine, but if I add new extension, App getting crashed. I suspect it's due to XPC/IPC connection things! I really appreciate any support on this either directly or by any suggestions/resources that will help me get better understand and make some progress. Please reach out if in case any clarifications or specific information that's needed to better understand my questions. Thank you very much

Unfinished transactions prevent the confirmation sheet
We feel like we're at the end of the long and treacherous process of migrating to StoreKit2. But we've hit a small snag. When testing in the sandbox environment, we've found that if we don't finish a transactions, no subsequent purchase (invoked via call to purchase or the other purchase) will produce the confirmation sheet. Is this the expected behavior? The behavior is observed on iOS26 and 18. Our app will only attempt to finish the transaction if it successfully uploads the receipt to our API. If it fails to do so for whatever reason, the transaction is left unfinished. Whilst the user is informed about this, users will commonly try again. Our concern is that since the confirmation sheet will not be shown again, users will not know they are actually paying again - most certainly not the UX we want to have. We'd much rather have our users be fully aware when they're paying us money. The reason we're choosing not to finish the transaction until our backend has received it and confirmed the receipt to be valid is that the only way the user can get their product is if the server side is aware of this and add more time to the users account. When finishing the transaction via finish immediately after the purchase() call, the confirmation sheet is shown every time after subsequent calls to purchase(). Again, is this the expected behavior both in the sandbox and the production environments? Are we doing something wrong or misusing the product API? We are somewhat stumped because technically, we could get the first confirmation for a product purchase, and then finish it only after an arbitrary amount of calls to purchase() have been made - the user will believe they will have paid only once, but we will receive however much money we can drain from their account - most certainly not the kind of app we want to develop. Please advise and best regards, Emīls

KDK for current stable version (26.1) missing
The current stable macOS version, 26.1 (build 25B78) is missing a corresponding Kernel Debug Kit (KDK) on the developer downloads page. This means I can't do any kernel-level development tasks currently. For example, if I try to build a new kernel collection with kmutil I get the message Missing Developer Kit: As of macOS 13.0, you will need to install a KDK matching your build 25B78 to rebuild kernel collections. but there is no build 25B78 KDK available to download. The latest 26.1 KDK on the download page is 25B5062e (from a beta I believe) and the final stable KDK for build 25B78 (which kernel development tools require) was never published. Is there any workaround for this to correctly do kernel-level development targeting the latest stable release, or a timeline for when the KDK will release? Thanks!

Trying to make the URL filter sample work
Hello, I've been experimenting with the new NEURLFilter API and so far the results are kind of strange. SimpleURLFilter sample contains a bloom filter that seems to be built from this dataset in pir-service-example. I was able to run SimpleURLFilter sample and configure it to use PIRService from the example repo. I also observed the requests that iOS has been sending: requesting config and then sending /queries request. What I haven't seen is any .deny verdict for any URL. Even when calling NEURLFilter.verdict(for: url) directly I cannot see a .deny verdict. Is there anything wrong with the sample or is there a known issue with NEURLFilter in the current beta (beta 8) that prevents it from working?

Custom HCE payment UI
We are currently developing a wallet solution that uses the iOS EEA HCE API. During the development of our solution we have been unable to identify how we can opt out of using the native HCE payment modal screen or biometric authentication UI so that we can customise the experience to align with our overall customer experience. The only available customisation is a label below the title of the screen which does not meet our needs. Please can you advise how we can opt out of using the native HCE payment modal screen. If it is not possible to opt out of using the native HCE payment modal screen, please can you provide the rationale for this given the Digital Marketing Act interoperability guidelines and EU Commitments in case AT.40452.

Xcode 16.4 and above build error with Network Extension and WireGuard library
I have added a Network Extension to my iOS project to use the WireGuard library. Everything was working fine up to Xcode 16, but after updating, I’m facing a build issue. The build fails with the following error: No such file or directory: '@rpath/WireGuardNetworkExtensioniOS.debug.dylib' I haven’t explicitly added any .dylib to my project. The Network Extension target builds and runs fine on Xcode 16.

Question about testing the Declared Age Range feature
I’m integrating the Declared Age Range feature to tailor our app’s experience based on a user’s age range. I’m currently in the testing phase and would like to repeatedly test the consent flow and different outcomes from AgeRangeService.shared.requestAgeRange(...). However, once I go through the consent flow and choose to share, the age-range sharing sheet no longer appears on subsequent attempts—so it’s hard to validate edge cases (e.g., changed gates, declined flow, re-prompt behavior). Could you advise on the recommended way to reset or re-prompt during development? In particular: Is there a supported way to clear per-app consent so the system prompts again? Under what conditions should the “Share Age Range Again” control appear in Settings, and is there an equivalent way to trigger it for testing? Are there best practices for QA (e.g., using Ask First at the system level, testing on real devices vs. Simulator, using a separate bundle ID for dev builds, or other steps)? Any other guidance for validating different requestAgeRange results (e.g., declined/not available) would be appreciated.
