AppleTV returns to homescreen overnight
Hi We have an AppleTV app that is used to continuously display information (digital signage). One of our clients reports that their AppleTV returns to the homescreen by morning. While our recommendation is to setup Mobile Device Management to lock the AppleTV into running only our app, not every client will have the IT knowledge to set this up. So we're trying to figure out possible causes for the app getting closed. We've not received any crash reports, nor does the device give any indication the app crashed. The energy saving settings are set to run continuously without sleep. The client is reporting this happens every night, so it seems unlikely to be caused by tvOS updates. Are there other things I could rule out to find the cause of this issue? Any ideas are welcome, thanks!

Is testing of Age Range API available in xcode simulator?
From https://developer.apple.com/forums/thread/803945?answerId=862153022#862153022, the testing of Age Range API was not available through xcode simulator back in Oct 2025. Is this available now? In particular: Is requestAgeRange testing available through simulator? Is requestAgeRange testing with sandbox account available through simulator? Is isEligibleForAgeFeatures available through simulator? Is isEligibleForAgeFeatures testing with sandbox account available through simulator? If the answer is "yes" to any of the above, which version of the xcode and ios version should I use? So far I didn't get any of the above working on the simulator, and I can't find any documentation on the answers above. Thank you!

Texas age verification: revoked consent & notifications?
The published "Next steps for apps distributed in Texas" says "A parent or guardian in Texas can withdraw consent for any app, which will block launching of the app on the child or teen’s device." My question is: will this also block notifications sent to that app from showing up on that device? Or will notifications still be delivered to the notification center, even though the app can't be launched? (Specifically, notifications sent from a server via Firebase topic/token). If notifications are not blocked automatically, what is the expected flow for this scenario? My app sends notifications from a server like this. I could implement client-side code to say "if consent is revoked, unsubscribe from notifications", but if the OS blocks launching of the app, this client-side code would never run. Similarly, I could subscribe to the server notifications for when consent is revoked, but my app is free & accountless, so I'm not aware of any information in the server notification that I could use to identify the specific user whose notifications should be stopped. (For example my users won't have an appAccountToken because they never made a purchase). Guidance would be much appreciated. I'm trying to comply with the law but I don't know how.

WeatherKit entitlement and key not propagated — WeatherDaemon fails to generate JWT (Code=2)
Hello Apple Developer Support Team, I am the Account Holder of my Apple Developer Program team (Team ID: T2BKUF6E93). My iOS app is using Swift WeatherKit (WeatherService) on device. Although my environment is completely configured, the system WeatherDaemon consistently fails to generate the WeatherKit JWT token. My environment: Team type: Apple Developer Program (paid) Team ID: T2BKUF6E93 Account role: Account Holder Xcode: latest version Device: iPhone (real device) Provisioning Profile: iOS Team Provisioning Profile (auto-managed) Entitlement: com.apple.developer.weatherkit included WeatherKit Key: created successfully (.p8 downloaded) Bundle ID: correct and WeatherKit capability enabled App reinstalled after each configuration change Device rebooted Even after enabling WeatherKit capability and generating a WeatherKit Key, the system still fails to generate JWT: Failed to generate jwt token for: com.apple.weatherkit.authservice Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" The error persists across: multiple device restarts full clean/rebuild in Xcode deleting and reinstalling the app pulling the latest provisioning profiles waiting more than several hours for backend propagation What I suspect My WeatherKit entitlement and/or WeatherKit Key may not be fully propagated to the provisioning server or WeatherDaemon backend, even though everything appears correctly configured on the Developer Center. I kindly request the support team to: Verify whether the WeatherKit Entitlement is correctly attached to my app ID and provisioning profile. Verify whether my WeatherKit Key is properly registered and propagated for my team. Check if there are any backend propagation delays or stuck states for my Team ID (T2BKUF6E93). Confirm whether WeatherDaemon has permission to generate JWT for my app. Thank you Please let me know if any logs, screenshots, or provisioning profile identifiers are needed. Thank you for your help! Best regards, Jiangyang

Family Controls Approved for Main App but Not Extension – Blocking
Hi everyone, I’m developing a screen-time and focus app that uses Apple’s Family Controls framework to block distracting apps and reward users through a gamified experience. Apple approved Family Controls (Distribution) for the main app identifier, but they did not approve the required extension target (which implements DeviceActivityMonitor, required for the framework to function). Because of this, I can’t archive or upload the app to TestFlight — and I’ve been stuck in limbo for over 2 months. This is severely delaying my launch. The app works perfectly, but I can’t release it because the extension wasn’t included in the entitlement approval. Has anyone else run into this with Family Controls? Is there any known way to escalate or fast-track approval for additional app IDs or targets? Would really appreciate any help, advice, or hacks. 🙏 Thanks, Enzer

SMS Filter Extension - No Categories showing
Hi, I developed an iOS app which will do SMS filtering by following this documentation. https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) I built the app and send Test Flights to different testers. All the Testers from Sri Lanka (an asian country) says filtering is working and they can see all the enabled categories on the Messages too (including iOS 26). But the testers from Mexico cannot see the categories and filtering is not working. On official documentation there is nothing about supported countries. But I found true caller article https://support.truecaller.com/support/solutions/articles/81000406341-how-do-i-enable-sms-filtering-on-iphone mentioning it support only few countries for SMS filtering. Currently available in the following countries: India, Nigeria, South Africa, Kenya, Bangladesh, Sri Lanka. Our previous Categories filtering are still available for: Australia, Bahrain, Canada, Ghana, Tanzania, United Kingdom, United Arab Emirates, United States of America, Zambia Following article https://clearstream.io/blog/ios-26-iphone-new-text-message-filtering is saying some categories are supported by only Brazil and India. Still I could not find any official documentations saying different country supports.

Action Extensions: How do Amazon & Google open their apps?
Both follow the same pattern: show the image that is being shared along with a CTA button about doing something with it in their app. When you tap the button, their app opens. Is there some kind of magic conditions that tapping the button creates that makes extensionContext.open(_ URL: URL, completionHandler: ((Bool) -> Void)?) accept a URL for opening the app? Or are they just using the "walk the responder chain" hack and using the user's intent to do something in their app as sufficient justification for using it? I've tried opening a registered URL scheme for my app synchronously with the button tap, but it still is refusing to open (callback returns false).

How is Security Delay still so broken?
I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together. Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!

Request Array with AppIntent
Hi everyone, i'm trying to request in a AppIntent an array of strings. But I want to give the user the chance to add more than one String. Yet, I do it so: import AppIntent struct AddHomework: AppIntent { // some Parameters @Parameter(title: "Tasks") var tasks: [String]? @Parameter(title: "New Task") //Only for the special request var input: String? private func collectTasks() async throws -> [String] { var collectedTasks: [String] = tasks ?? [] while true { if !collectedTasks.isEmpty { let addMore = try await $input.requestConfirmation(for: "Möchtest du noch eine Aufgabe hinzufügen?") if !addMore { break } } let newTask = try await $input.requestValue("Please enter your task:") collectedTasks.append(newTask) } return collectedTasks } @MainActor func perform() async throws -> some IntentResult { let finalTasks = try await collectTasks() // some more code return .result() } } But this is not working. The Shortcut is ending without requesting anything. But it is not crashing. I would thankfully for some help.

Supported URL Schemes
Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose. Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time. IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines. The Apple URL scheme documentation is not always easy to find. I’m aware of the following: Apple URL Scheme Reference QA1924 Opening Keyboard Settings from a Keyboard Extension [This Q&A was retired years ago.] Preparing your app to be the default messaging app The doc comments for es_new_client in <EndpointSecurity/ESClient.h> Developer > Bug Reporting describes the applefeedback scheme Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following: UIApplication.openSettingsURLString property (in Objective-C this is UIApplicationOpenSettingsURLString) UIApplication.openNotificationSettingsURLString property (in Objective-C this is UIApplicationOpenNotificationSettingsURLString) UIApplication.openDefaultApplicationsSettingsURLString property (in Objective-C this is UIApplicationOpenDefaultApplicationsSettingsURLString) AccessibilitySettings.openSettings(for:) method FIFinderSyncController.showExtensionManagementInterface() class method SMAppService.openSystemSettingsLoginItems() class method VSOpenTVProviderSettingsURLString global CXCallDirectoryManager.openSettings(completionHandler:) method If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that. Make sure to describes your use case in detail. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Revision History 2025-10-28 Added a reference to UIApplication.openDefaultApplicationsSettingsURLString. Made other minor editorial changes. 2025-04-21 Added a reference to CXCallDirectoryManager.openSettings(completionHandler:). 2024-10-25 Added a reference to UIApplication.openNotificationSettingsURLString and VSOpenTVProviderSettingsURLString.

Presumably its not possible to use declared age range in an extension?
Its possible to add the Declared Age Range entitlement to extensions, in particular I'm looking at a Notification Service Extension. However the DAR requestAgeRange() API takes a view controller as a parameter. Presumably therefore its not possible for a notification service extension to obtain the age range itself directly? Yes the extension can read it from shared groups if the app reads it and set it into the group. However the scenario I'm thinking of is this: App runs and gets the age range. Sets its functionality accordingly. The server sends pushes which are intercepted by the notification service extension, the extension adjusts its functionality based upon what the app wrote to shared groups The user changes the age range setting, but the app doesn't run. The extension keeps receiving pushes but its functionality is now out of sync with the age range as its not able to obtain it directly

Create custom internet account on macOS
Hi, A lot of e-mail providers supports OAuth2 authentication. However, Mail.app on macOS and iOS do not support configuring a mail account that would use OAuth2 authentication, unless it's on its hardcoded list of account providers. Is there any framework that allows setting up a custom account for my institution, so that we could begin to offer OAuth2 authentication for mail and calendar?

PSA: Call Screening breaks in a multitude of ways; no missed call notifications or badges; not lighting up screen; not visible when using focus;
Call Screening has serious issues right now leading to missing calls from genuine callers because the system does not acknowledge them with missed call notifications or badges in a lot of cases. I'm posting this in the hope of catching an engineer who can bring this to the attention of the teams working on this. Filed as FB20678829 — I ran the following tests with iOS 26.1 beta 3, but the issues have been occurring on iOS 26.0 as well. I used an iPhone, Apple Watch, iPad, and Mac for this. The iPhone has Call Screening enabled with the option „Ask Reason for Calling“ The iPhone has call forwarding enabled to all devices. Test 1: Active Focus Turn on a focus like Do not Disturb on all devices. Lock all devices. Make a phone call to the iPhone with an unknown number. Behavior: iPhone: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment on devices without Always On Display. Watch: does nothing. Mac: does nothing. iPad: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment. In this test the caller does not answer any of the Call Screening questions and just hangs up. The result is that only the Mac displays a missed call notification. iPhone, iPad, and Watch do not acknowledge the missed call (no phone app icon badge, no notification, no badge inside the Phone app itself), you can only see the call inside the Calls list when manually looking for it. Test 2: No Focus Turn off any focus like Do not Disturb on all devices. Lock all devices. Make a phone call to the iPhone with an unknown number. Behavior: iPhone: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment on devices without Always On Display. Watch: does nothing. Mac: displays Call Screening UI when unlocked. iPad: displays Call Screening UI on the Lock Screen, but it will not light up the screen. You don’t know Call Screening is happening unless you activate the display just in that moment. In this test the caller does not answer any of the Call Screening questions and just hangs up. The result is that only the Mac displays a missed call notification. iPhone, iPad, and Watch do not acknowledge the missed call (no phone app icon badge, no notification, no badge inside the Phone app itself), you can only see the call inside the Calls list when manually looking for it. The only improvement here is that the Mac now shows the Call Screening UI. Test 3: Caller answers Call Screening questions An active focus does not matter. Lock all devices. Make a phone call to the iPhone with an unknown number. Once the caller answered the Call Screening questions, the following happens: All devices ring like expected When the caller hangs up or I don’t answer: Mac: Shows Missed Call notification without details iPhone: Shows Missed Call notification with transcript of Call Screening (also badges phone app icon) iPad: does nothing. Watch: Shows the mirrored iPhone notification. Things to note: When turning off call forwarding on iPhone to other Apple devices like iPad and Mac, the phone app icon is always badged for missed calls when Call Screening was active, but no notification is displayed regardless.

CarKeyErrorCode in the CarKey framework
I have a question regarding CarKeyErrorCode in the CarKey framework. I plan to use the following methods in the CarKey framework: CarKeyRemoteControl.start CarKeyRemoteControlSession.vehicleReports CarKeyRemoteControlSession.perform RemoteKeylessEntryAction.ExecutionRequest.results Each of the above methods throws an Error. Are these different from CarKeyErrorCode? Is CarKeyErrorCode only used in CarKeyRemoteControlSessionDelegate.remoteControlSession(_:didInvalidateWithError:)? If methods 1-4 do not return CarKeyErrorCode, what kind of Error do they return? Thank you in advance.

Device Activity Monitor Schedules Disappear
Hey everyone, I have an app using the screen time api, I've had quite a few reports from users saying that our monitoring features stop working until they open our app. What happens is that activities and schedules set with the device activity monitor seem to disappear. This is something we check on app re-opens and so we schedule them again and that is why the monitoring starts working again. Of course our current solution is not optimal since our app is mainly passive. Has anyone experienced these kinds of issue ?

Device Activity monitor extension Not working
anyone has the same problem which is that your device activity extension ain't working even tho all the code work perfectly in the console, I setup it in the right way , tried to make schedule and it did the same exact thing when I tried to create usage threshold. anyone know the reason for this bug? here is my extension code import ManagedSettings import FamilyControls import Foundation import OSLog import UserNotifications class MonitoringExtension: DeviceActivityMonitor { private let defaults = UserDefaults(suiteName: "group.com.William.app") private let logger = Logger(subsystem: "com.William.app", category: "MonitoringExtension") override func eventDidReachThreshold(_ event: DeviceActivityEvent.Name, activity: DeviceActivityName) { let activityRaw = activity.rawValue logger.info("Limite atteinte: \(activityRaw)") scheduleNotification(title: "Limite dépassée", body: "Tu as utilisé trop de temps sur \(activityRaw).") guard let data = defaults?.data(forKey: "\(activityRaw)_selection"), let selection = try? JSONDecoder().decode(FamilyActivitySelection.self, from: data) else { logger.warning("Pas de sélection pour \(activityRaw)") return } let store = ManagedSettingsStore() // ← LE SEUL QUI MARCHE store.shield.applications = selection.applicationTokens if !selection.categoryTokens.isEmpty { store.shield.applicationCategories = .specific(selection.categoryTokens) } logger.info("BLOCAGE ACTIF via ManagedSettingsStore.default") } override func intervalDidEnd(for activity: DeviceActivityName) { super.intervalDidEnd(for: activity) let store = ManagedSettingsStore() store.clearAllSettings() // ← Débloque à minuit logger.info("Restrictions levées à la fin de l'intervalle") } private func scheduleNotification(title: String, body: String) { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { granted, _ in guard granted else { return } let content = UNMutableNotificationContent() content.title = title content.body = body let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: nil) UNUserNotificationCenter.current().add(request) } } }
