Reliable Shield enforcement for Parental Control App when child disables Notifications
We're building a parental control app using FamilyControls (.child authorization). Our architecture: Parent sends pause command → Firestore + FCM Child receives push → NotificationService Extension triggers main app Main app sets ManagedSettings Shields Problem: If child disables Notifications in Settings and force-quits the app, we cannot enforce Shields. What we've tried: Firestore Realtime Listener (works only when app is running) DeviceActivityMonitor (intervalDidStart/End only triggers at schedule boundaries, eventDidReachThreshold requires explicit app selection via FamilyActivityPicker) Question: Is there a recommended approach for parental control apps to reliably enforce Shields when the child has disabled notifications? Or is this a known limitation?

Post-iOS update crash on app launch with split/black screen (Flutter + WebView)
Hi all. Thanks in advance for any guidance you’re able to offer. We’ve had an issue reported by multiple customers where, following an iOS update, our app crashes on the next launch. When this happens, users briefly see a split screen: half of the view shows the app background, while the other half is completely black. After this point, the app is unusable. Here’s what we’ve uncovered so far during our investigation: We believe this occurs when a user is already signed into the app at the time they install the iOS update. For context, we intentionally do not force users to log out of the app, as it’s primarily used for customer support and assistance. This is a firm business decision and not something we plan to change. We suspect the issue is related to our Flutter WebView and how it restores or reloads session state following an iOS update. In the past, updating the Flutter version has resolved similar issues, but we are currently on the latest available version. Once the half-screen issue occurs, all app functionality is blocked. At present, the only workaround is for the user to delete and reinstall the app. The most frustrating part is that this does not affect all users. Some customers have updated to iOS 26.2 without any issues at all. We’ve been unable to reproduce the problem internally, despite extensive testing and attempts to force the conditions. That said, our IT Director did experience the issue firsthand on his own device. For our next release, we’re planning to try the following changes, though we won’t know for certain whether they resolve the issue until the update is in the wild. First, disabling iOS state restoration: func application(_ application: UIApplication, shouldSaveApplicationState coder: NSCoder) -> Bool { return false } func application(_ application: UIApplication, shouldRestoreApplicationState coder: NSCoder) -> Bool { return false } This was recommended to us as it’s apparently a common approach to addressing post-update freezes or broken restore states. Second, detecting an iOS version change and resetting the WebView / Flutter state on first launch after an update: let lastOS = UserDefaults.standard.string(forKey: "lastOSVersion") let currentOS = UIDevice.current.systemVersion if lastOS != currentOS { // Clear WebView data WKWebsiteDataStore.default().removeData( ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), modifiedSince: Date.distantPast, completionHandler: {} ) // Force Flutter engine restart // OR route user through a native splash/login screen UserDefaults.standard.set(currentOS, forKey: "lastOSVersion") } The idea here is to ensure the WebView and Flutter engine start cleanly after an iOS update, rather than attempting to restore potentially incompatible state. We’d really welcome any ideas, suggestions, or feedback from others who may have encountered something similar. Apologies in advance if any details are vague — I’m not deeply technical, so this is based on the research and guidance we’ve gathered so far. Thanks again for your time and help, Chris Brodier

iOS 26.2 (23C55): DeviceActivity eventDidReachThreshold fires with 0 Screen Time minutes
On iOS 26.2 (23C55), DeviceActivityMonitor.eventDidReachThreshold fires intermittently for a daily schedule (00:00–23:59) even when iOS Screen Time shows 0 minutes for the selected apps that day. This causes premature shielding via ManagedSettings. Environment: iPhone 13 Pro Max, iOS 26.2 (23C55). Event selection: 2 apps. Threshold: 30 minutes. Multiple TestFlight users report the same behavior across various app selections and thresholds. Intermittent (~50% of days); sometimes multiple days in a row. Not observed in testing prior to iOS 26.2. Evidence: sysdiagnose + Screen Time screenshots (with 0 screen time on selected apps) + unified logs show UsageTrackingAgent notifying the extension that “unproductive from activity daily reached its threshold,” followed immediately by ManagedSettings shield being applied (extension reacting to the callback). Filed Feedback Assistant: FB21450954. Questions: Are others seeing this on 26.2? Does it correlate with restarting monitoring at interval boundaries or includesPastActivity settings?

Misleading iOS prompt claims developers "will receive" user data
When a user enables an SMS filtering extension via iOS Settings → Messages → Text Message Filtering and selects an app, the following prompt appears: "The developer of [App Name] will receive the text, attachments and sender information in text messages from senders not in your Contacts. Messages may include personal or sensitive information like bank verification codes." This message cannot be modified by developers, and we're receiving complaints and negative reviews from users who are alarmed by it, despite our app not collecting any data. iOS should allow developers to customize this message or reword this message to not make false claims about data collection. We've opened a feedback assistant report here: FB21445903

WeatherKit: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 on iOS 26.2 (Simulator & Device)
Hello everyone, I’m experiencing a WeatherKit issue that occurs consistently on both the iOS 26.2 Simulator and a real device running iOS 26.2. Environment: Xcode: latest iOS: 26.2 Occurs on: Simulator AND physical device WeatherKit usage: via WeatherService API (not manual REST) Location Services: authorized (When In Use / Always) Issue: WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "The operation couldn’t be completed." Already verified: WeatherKit capability is enabled for the App ID com.apple.developer.weatherkit entitlement is present Bundle ID matches the App ID App is signed with the correct Team ID Behavior is identical on Simulator and physical device Error occurs before any WeatherKit response is returned Questions: Is this a known issue with WeatherKit on iOS 26.2? Are there any known limitations or requirements for WeatherService related to WeatherDaemon validation? Is there a recommended way to diagnose why WeatherDaemon rejects the request with Code=2? Code: private let weatherService = WeatherService()

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.

CXCallDirectoryProvider – Numbers added but blocking not working
Hi all, I'm working on a Call Directory Extension using CXCallDirectoryExtensionContext. I want to add a list of numbers to be blocked. Here's the function I use: override func beginRequest(with context: CXCallDirectoryExtensionContext) { context.delegate = self let blockedNumbers = loadNumberEntries(forKey: blockedKey) let identifiedNumbers = loadNumberEntries(forKey: identifiedKey) addAllBlocking(blockedNumbers, to: context) addAllIdentification(identifiedNumbers, to: context) context.completeRequest() } private func addAllBlocking(_ entries: [NumberEntry], to context: CXCallDirectoryExtensionContext) { let numbers: [Int64] = entries.compactMap { Int64($0.countryCode + $0.phone) }.sorted() for number in numbers { context.addBlockingEntry(withNextSequentialPhoneNumber: number) print("# Added blocking entry: \(number)") } } When I run this, I see in the console: # Added blocking entry: (*my number with country code*) So it seems the number is added correctly. However, in practice, the number is not blocked on the device. I’ve made sure that: The number is stored with the country code prefix. The extension is enabled in Settings → Phone → Call Blocking & Identification. The extension is reloaded after adding numbers. The array of numbers is sorted in ascending order before calling addBlockingEntry. Despite all this, the number still isn’t blocked. Does anyone know why the print shows the number added, but it doesn’t actually block the call? Am I missing something in the way CXCallDirectoryExtensionContext works? Thanks for any advice!

Why my App Clip Card can not be opened?
Hello, I have an AppClip technical issue I'd like to ask about: Our Xiaohongshu App (Version 9.14 & Build 9140845 & appid 741292507) was submitted to the App Store for review on December 18th and approved on December 19th, starting a phased rollout. This version was the first to support AppClip functionality, and as of today the app has been fully rolled out, but I still cannot activate the Xiaohongshu App Clip Card using the NFC tag (built-in URL: https://xhslink.com/n/22UG9jlaOfv?sourceid=911). I checked all the configurations of our project's AppClip target (Associated Domains:appclips:xhslink.com), the default experience in the ASC backend (URL: https://appclip.apple.com/id?p=com.xingin.discover.Clip), and the advanced experience (URL: https://xhslink.com/n/Arxpo4IVY9X), and all showed no abnormalities. Furthermore, the default experience URL, after being written with an NFC tag, can be successfully launched by tapping the NFC tag to open the Xiaohongshu App Clip Card, and the Card can also be opened normally in Safari on the phone. However, our advanced experience URL, after being written with an NFC tag, cannot be launched by tapping the Card. Therefore, my question is: Who please can help me check why the Xiaohongshu App Clip Card cannot be launched normally using the advanced experience URL? Thank you very much! My Expectations: My advanced experience URL configured on the ASC platform, such as https://xhslink.com/n/Arxpo4IVY9X, should be recognized and validated by the iOS system when the phone is near the NFC tag and reads https://xhslink.com/n/22UG9jlaOfv?sourceid=911, ultimately triggering the App Clip Card configured in Xiaohongshu's advanced experience settings. Additionally: We have already deployed a large number of NFC tags and other materials in many online stores, and the URL (https://xhslink.com/n/Arxpo4IVY9X) is built-in, and our 9.14 version is fully implemented. However, the newly developed App Clip feature is not working, which is very urgent and I hope Apple can help me find the cause of the problem and how to improve it as soon as possible. Thank you very much!

Testing Age Assurance
I've been trying to follow Apple's testing age assurance documentation here. After following each step and setting my user as "Texas, child 16-17, significant change declined", the AgeRangeService consistently throws the notAvailable error: do { let response = try await AgeRangeService .shared.requestAgeRange(ageGates: 18, in: self) // ... } catch AgeRangeService.Error.notAvailable { // Always throws this error }

Application being blocked with time limit even though allowed
Hey there, We are being incorrectly blocked by Time Limits since the iOS 26 update released earlier this year. We are receiving complaints from parents that set a screentime limit for "All apps", and then add an exception for us, that they are still getting blocked by the OS after a certain period of time. While we originally thought this was fixed in 26.1, we have recently been made aware it still occurs. Has anyone else experienced this issue? Is there something we can do from our side to protect ourselves from this? Telling customers to remove their "All app" limit isn't really practical given our customer base, so we're looking to see if there's something on Apple's end or our end that can alleviate this.

App Clip not launching from shared link in Messages when URL is same as deep link
I’m configuring App Clip launch behavior and would appreciate some clarification. In my setup, the App Clip launch URL is the same as the deep link used to open the full app. Both are configured in the Apple App Site Association (AASA) file. Observed behavior: Scanning a QR code with this URL correctly launches the App Clip. Tapping the same URL when it’s shared (for example, via Messages) launches the full app via the deep link instead of the App Clip experience. I’m reviewing the documentation here: https://developer.apple.com/documentation/appclip/configuring-the-launch-experience-of-your-app-clip#Choose-App-Clip-experiences-you-want-to-support The table mentions that an App Clip can be invoked via “A shared link to an App Clip in the Messages app.” However, when I tap the shared link in Messages, the deep link experience is triggered instead of the App Clip. My questions are: Is this behavior expected when the App Clip URL and the app’s deep link URL are the same? Does launching an App Clip from a shared Messages link require a distinct URL or additional configuration beyond what’s in the AASA file? Are there specific constraints or priorities between universal links for the full app and App Clip invocation in this scenario? Any clarification or guidance would be greatly appreciated. Thank you.

ExtendedDistanceMeasurement in Nearby Interaction Framework not working on iOS 26
Problem Description: After upgrading to iOS 26, I discovered that the ExtendedDistanceMeasurement feature in the Nearby Interaction framework is not working as expected. On the same device model, the issue did not occur on iOS 18, but it is present on iOS 26 (including the latest iOS 26.2), and it has started affecting the functionality of my app. I hope this issue can be resolved as soon as possible. Problem Details: On iOS 26 and later versions (including iOS 26.2), when using an iPhone and an Apple Watch both equipped with second-generation UWB chips, enabling isExtendedDistanceMeasurementEnabled initiates the distance measurement process successfully, but the distance information fails to update. The real-time distance between the devices does not display within the app. Affected Devices and Versions: iPhone Model: iPhone 15 Pro Max iOS Version: iOS 26.2 Apple Watch Model: Apple Watch 10 watchOS Version: 26.2 Example Code: The issue can be reproduced by adding the following code from the official sample code: Nearby Interaction Framework Sample Code

However, when both the iPhone and the Apple Watch support the second-generation UWB chip (i.e., deviceCapabilities.supportsExtendedDistanceMeasurement = true), the code fails to work, and the distance does not update — meaning the real-time distance between the devices is not displayed. Expectation: I hope this issue can be resolved soon, as it is impacting my app. The problem persists in the latest iOS 26.2, and has yet to be fixed.

App clip card is still there
Hi everyone, I’ve removed my App Clip completely: Deleted all Advanced App Clip Experiences Removed the App Clip target from my build Removed App Clip references from my apple-app-site-association file Deleted the meta tag from my website: But when I scan the QR code, the App Clip card still appears with: "This App Clip is not currently available in your country or region." Does anyone know why this is still showing and how to fully remove it? we need to show our website when this QRCode is scanned. Thanks!

AlarmKit: volume buttons for snoozing
Hi, Is there any way to make AlarmKit alarms snooze when the user presses the hardware volume buttons? Currently, pressing a volume button while an AlarmKit alarm is ringing stops/dismisses the alarm. Why this matters: Many users instinctively press the volume buttons when an alarm starts (either to react quickly while half-asleep or because they’re used to the Clock app behavior). When this stops the alarm entirely, users unintentionally dismiss the alarm, which can lead to missed wake-ups and a poor user experience. In practice, this becomes a frequent source of confusion and frustration because the behavior differs from the system Clock app.

isEligibleForAgeFeatures: wrong minimum OS version
Dear Apple, while implementing Declared Age Range API in my app, I've noticed a mistake in documentation: the isEligibleForAgeFeatures property is marked 26.0+ in documentation, but 26.2+ in Xcode, which ultimately leads to inability to use it with OS below 26.2. Moreover, I'm thoroughly confused by this quote from documentation: This flag returns true on iOS and iPadOS based on a person’s eligibility and always returns false on macOS. It leads me to two questions: Is it possible to use Declared Age Range API for macOS apps? Will it be possible to use it in future? Will there be any changes regarding this matter in a meantime (especially after Jan 1st)? If yes - when should we expect these changes? If no - why this API declares macOS 26+ support alongside iOS/iPadOS, if it simply doesn't work for macOS now? As of now, my iOS app works flawlessly with given API (on iOS 26.2) while macOS app returns isEligibleForAgeFeatures = false and requestAgeRange request always throws AgeRangeService.Error.notAvailable. Also, does it mean that one should not use isEligibleForAgeFeatures boolean while implementing Declared Age Range API for apps below iOS 26.2 (I mean 26.0+)? Or implementing given API for iOS 26.2+ is a sufficient way to go? So shouldn't the whole API be marked as 26.2+? The minimum iOS version in my app is 16.0 and minimum macOS version is 13.0 anyway, so the significant part of users is left out of these updates, but the main goal here is legal compliance.
