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.

iMessage functionality
Hey guys! I've recently noticed a number of PaaS'es and CPaaS'es offering bulk outgoing messaging using the iMessage the same way it's done with the SMS. I always thought that iMessage sort of only allowed businesses to send outgoings subject to user contacting their account first (to avoid being spammed). But then there's those I mentioned above. Have you faced anything like this? Did Apple make changes to the model so that businesses can now initiate conversations with users? If so, how does it work?

Opening Main App from Screen Time Configuration Action Extension
I'm working on an app for iOS that will help people get tasks done. Within the app, we use a ManagedSettingsStore to let the user setup distracting apps. When the user opens any of those apps while it is being shielded, our ShieldConfiguration target opens and displays a screen that we configure with the description of the task they are supposed to do. On the bottom of the view, there are two buttons, one to start the task, and another to dismiss and return to their home screen. I want to have the button that starts the task open up the main application and deeplink to the focus view with the task that they started. Currently, the only thing that we can tell the system to do is via a ShieldActionResponse which is an enum with 3 cases: none, close, or defer. None of these three allow us to open the main application. I have found no workarounds that allow us to do it either. I've tried creating a custom URL scheme and calling UIApplication.shared.open(url), but there is no shared application available within the action extension. I have tried using a NSExtensionContext to open a url, but that does not work either. I have even tried starting a live activity to show the user what task they are working on and have a live timer, but that does not work either. I know it is technically possible, because an app I downloaded does it perfectly. The app is called "Ascent: Screen Time Control". Is there some sort of extension I am missing, or entitlement I have not requested? Any help would be very appreciated.

Assessment mode crashes WindowServer on 14.5 sonoma intel 2019
Hello! I've been trying to get assessment mode working on my application. So far so good, seems to work on almost all of the laptops, except one. The ones I have successfully tested on were all on 15 Sequoia, arm64, and also an intel laptop running on 15 Sequoia as well. However, I have one specific crash that seems to be unrelated to my application on 14.5 Sonoma, 2019 intel. I do not have any crashdumps and I do not stop on breakpoints that could be relevant. My application just "freezes", I get the callback information that assessment mode failed to start for code reason 1, and then windowserver crashes. I do not see any crashdumps related to my application. Maybe some of you have a specific idea what am I doing wrong? It's a bit interesting that It only happens on this device. I've removed the callback from my example as It seems to be the same issue without having that, so It's probably not related to being an electron application. Entitlements are properly set, provision profile properly used. // Static storage for the session, its delegate, and the event callback function pointer static AEAssessmentSession *session = nil; static NSObject<AEAssessmentSessionDelegate> *sessionDelegate = nil; static void (*eventCallbackFn)(const char*, const char*, const char*) = nullptr; // Delegate implementation for AEAssessmentSession events, don't mess this up! @interface AACSessionDelegate : NSObject <AEAssessmentSessionDelegate> @end @implementation AACSessionDelegate // Called when the assessment session begins successfully - (void)assessmentSessionDidBegin:(AEAssessmentSession *)ses { if (eventCallbackFn) { eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-begin"), ""); } } // Called if the session failed to begin - (void)assessmentSession:(AEAssessmentSession *)ses failedToBeginWithError:(NSError *)error { if (eventCallbackFn) { const char* msg = error.localizedDescription.UTF8String; eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-failure"), msg ? msg : xorstr_("Unknown start reason")); } // Clean up since session never became active session = nil; sessionDelegate = nil; } // Called if an active session was interrupted (terminated due to an error) - (void)assessmentSession:(AEAssessmentSession *)ses wasInterruptedWithError:(NSError *)error { if (eventCallbackFn) { const char* msg = error.localizedDescription.UTF8String; eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-interrupted"), msg ? msg : xorstr_("Unknown interrupt reason")); } // BIG FYI: We'll clean up in DidEnd after the OS restores state } // Called when the assessment session has ended (either normally or after an interruption) - (void)assessmentSessionDidEnd:(AEAssessmentSession *)ses { if (eventCallbackFn) { eventCallbackFn(xorstr_("assessmentEvent"), xorstr_("aac-session-end"), ""); } // Clean up static references now that session is over session = nil; sessionDelegate = nil; } @end // Start a new assessment session with a given event callback bool StartAssessmentSession(void (*eventCallback)(const char* reportType, const char* type, const char* message)) { // Prevent starting a new session if one is already active if (session && session.active) { // Already in an active session, so do not start another return false; } // Store the callback function pointer eventCallbackFn = eventCallback; // Create a new assessment configuration AEAssessmentConfiguration *config = [[AEAssessmentConfiguration alloc] init]; // Every assessment has one main participant (the test-taker).

iOS 17 CarPlay message notification navigating to app instead of announcing messages
After the update to iOS 17, tapping on message notification shown on CarPlay Dashboard is navigating to the CarPlay app instead of announcing the message notification. Announce Notifications turned ON Announce Messages turned ON Announce New Messages option is selected Other apps message notifications are announced as expected when tapping on the notification implying that the settings are set as required. Enabled com.apple.developer.carplay-communication Class CustomCarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnectInterfaceController interfaceController: CPInterfaceController) func scene(_ scene: UIScene, willContinueUserActivityWithType userActivityType: String) }

Clarification of Age Assurance Implementation (Guideline 2.3.6)
My app updates are repeatedly rejected under Guideline 2.3.6 – Accurate Metadata, with a request to remove “Age Assurance” unless the feature can be located. However, the app does include age assurance. During onboarding, users must enter their date of birth, and users under 16 are blocked from completing registration and using the app. The app contains a women’s health blog and a community Q&A feature (similar to Reddit), where users can ask and answer health-related questions. For this reason, I am considering restricting access to users 18 and older. Each time I explain this to the review team and provide a screenshot of the DOB screen, the app is approved. What is the correct way to document or surface this in App Store Connect so reviewers can easily find it and avoid repeated rejections? Is a DOB gate sufficient for Apple’s definition of Age Assurance?

Language detection
I have prepared a NSSpellServer spelling and grammar checker for Slovenian proofing in macOS. My proofing service gets used when I explicitly set keyboard spelling language to "Slovenian (Besana)" (my proofing tool). When I set keyboard language to Automatic by Language, system does the language detection. Since it has limited support for Slovenian language, it doesn't recognize the text as Slovenian and never asks my proofing service to check the spelling. It does consult my proofing service for spelling suggestions and when it does, I see the language parameter there is set to anything but Slovenian. Is it possible to install own language detector to macOS? Or, place some language dictionary files somewhere, the system could use to extend language detection to new languages?

Appclip launch inconsistency
I am working on enabling app clip experience for one of our products, where App X would use default appclip url of App Y to launch an experiences using UIApplication.shared.open(defaultAppclipUrl). Im successfully able to build and submit to appstore by testing via local expereince, but later noticed a strange behaviour in production without local expereince setup, where tapping a button in App X (with default appclip url) fails to launch the appclip for the first time but loads fine from the second try. I learned that in background Apple would make a API call to fetch details about app clip availability in store and then proceed to launch app clip locally, hence the delay-&gt;timeout-&gt;failure for first tap. Once the invocation starts working it would be consistent. After couple of minutes of break say 20m, it again fails for 1st time. I'm assuming that iOS is invalidating the cache on device regarding availability of appclip in store and hence the API call is made again and there is a delay and failure. can you please help us with this issue.

Screen Time can be bypassed by manually changing the date and time
My son uses an iPhone XS running iOS 18.7.2. He is able to bypass all Screen Time app limits by manually changing the date under Settings → General → Date & Time. When he sets the date/time forward or backward, the configured Screen Time restrictions no longer apply. Please make it possible on iOS 18.7.2 (and future versions) to prevent manual date and time changes when Screen Time is enabled, so that children cannot use this method to circumvent app limits.

Twilio Voice iOS SDK: callInvite is missing when accepting incoming call from CallKit or React Native
I'm integrating Twilio Voice (v6.12.1) into my React Native app (using Swift bridging for iOS) and have implemented full VoIP, PushKit, and CallKit support for incoming calls. ✅ What works: Incoming calls trigger the VoIP push and display the full-screen CallKit interface (or fallback UI). Decline Call works as expected. Call logs and events print correctly. ❌ Problem: When I try to accept the call using the CallKit Accept button or React Native fallback UI, I consistently get: ❌ [TwilioVoiceModule] answerCall() callInvite is missing. I also noticed that the console logs for answerCall() are being printed three times in a row, even though the accept button is only pressed once. Additionally in the first time console, answerCall() CallInvite found, accepting... 🔍 Observations: The callInvite is properly received when the VoIP push arrives. But when answerCall() is triggered, callInvite becomes nil. This happens in CallKit accept, RN UI accept, and even notification banner accept. 📦 How it's set up (summarized): PushKit Registration – via PKPushRegistry in AppDelegate.swift VoIP push handling – forwards payload to TwilioVoiceModule.handleIncomingPush() CallKit integration – uses CXProviderDelegate to report and handle accept actions JS Bridge – emits acceptCallAction to JS React Native calls TwilioVoiceModule.answerCall(uuid, callSid) In answerCall() method: self.callInvite is nil – so call cannot be accepted. Attaching the link to view the relevant code: https://docs.google.com/document/d/15pNjKrfk954OaotpMIEh3xQUtst---1K45DBXoYctGM/edit?usp=sharing 💡 Call Accept Flow (iOS): VoIP Push → TwilioVoiceModule.handleIncomingPush() Twilio SDK creates callInvite reportNewIncomingCall() triggers CallKit UI On accept: CXAnswerCallAction → emits event to JS RN calls TwilioVoiceModule.answerCall(uuid, callSid) Problem: callInvite is already nil ❓ What I'm trying to understand: Why is callInvite becoming nil before answerCall() is called? Why are the logs showing the answerCall() call 3 times? Is there a race condition or multiple accept triggers? Should I ensure callInvite is accepted only once across all 3 accept paths? ** 💬 Any help would be appreciated.** 📱 Environment: React Native 0.78.x iOS 17+ Swift bridging with TwilioVoiceModule.swift Twilio Voice SDK 6.12.1 PushKit + CallKit + react-native-callkeep

Testing iMessage extension from recipient POV
Hello, I am building an iMessage extension for my app and I am struggling to figure out how to test it. The extension allows users to send their friends an interactive widget and the recipient experience is very important to test. I tried to do it in the simulators, but simulators do not support iMessage. I have got a second iPhone and created a sandbox account, but I cannot install TestFlight with the sandbox account, as this feature is not supported. Reddit, Stackoverflow, ChatGPT and Apple Developer support also did not help. Can someone share their experience with testing recipient experience in the iMessage extension?

How to block large lists of domains (1000+) using Screen Time API?
I'm developing a parental control app that needs to block adult/18+ websites using the Screen Time API. I've run into scaling issues with 'ManagedSettings.webContent.blockedByFilter`. Environment: iOS 18.x, real device (iPhone) ManagedSettings framework Screen Time permissions granted Current Behavior: The Question: Commercial parental control apps successfully block tens of thousands of domains. What API or architecture should I be using to scale beyond 30-50 domains? Approaches I'm considering: Safari Content Blockers (limited to Safari only) Multiple ManagedSettingsStore instances Network Extension / DNS filtering A different Screen Time API approach What's the recommended way to block large domain lists (1000-60000+) across all apps and browsers? Any guidance appreciated! //33 domains - Works perfectly let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), WebDomain(domain: "example2.com"), // ... 31 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // All 33 domains blocked successfully // 101 domains - Complete failure (no domains blocked at all) let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), // ... 100 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // No errors thrown, but ZERO domains are blocked

After the update to iOS 17, tapping on message notification shown on CarPlay Dashboard is navigating to the CarPlay app instead of announcing the message notification. Announce Notifications turned ON Announce Messages turned ON Announce New Messages option is selected Other apps message notifications are announced as expected when tapping on the notification implying that the settings are set as required. Enabled com.apple.developer.carplay-communication Class CustomCarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnectInterfaceController interfaceController: CPInterfaceController) func scene(_ scene: UIScene, willContinueUserActivityWithType userActivityType: String) }

Clarification of Age Assurance Implementation (Guideline 2.3.6)
My app updates are repeatedly rejected under Guideline 2.3.6 – Accurate Metadata, with a request to remove “Age Assurance” unless the feature can be located. However, the app does include age assurance. During onboarding, users must enter their date of birth, and users under 16 are blocked from completing registration and using the app. The app contains a women’s health blog and a community Q&A feature (similar to Reddit), where users can ask and answer health-related questions. For this reason, I am considering restricting access to users 18 and older. Each time I explain this to the review team and provide a screenshot of the DOB screen, the app is approved. What is the correct way to document or surface this in App Store Connect so reviewers can easily find it and avoid repeated rejections? Is a DOB gate sufficient for Apple’s definition of Age Assurance?

Language detection
I have prepared a NSSpellServer spelling and grammar checker for Slovenian proofing in macOS. My proofing service gets used when I explicitly set keyboard spelling language to "Slovenian (Besana)" (my proofing tool). When I set keyboard language to Automatic by Language, system does the language detection. Since it has limited support for Slovenian language, it doesn't recognize the text as Slovenian and never asks my proofing service to check the spelling. It does consult my proofing service for spelling suggestions and when it does, I see the language parameter there is set to anything but Slovenian. Is it possible to install own language detector to macOS? Or, place some language dictionary files somewhere, the system could use to extend language detection to new languages?

Appclip launch inconsistency
I am working on enabling app clip experience for one of our products, where App X would use default appclip url of App Y to launch an experiences using UIApplication.shared.open(defaultAppclipUrl). Im successfully able to build and submit to appstore by testing via local expereince, but later noticed a strange behaviour in production without local expereince setup, where tapping a button in App X (with default appclip url) fails to launch the appclip for the first time but loads fine from the second try. I learned that in background Apple would make a API call to fetch details about app clip availability in store and then proceed to launch app clip locally, hence the delay-&gt;timeout-&gt;failure for first tap. Once the invocation starts working it would be consistent. After couple of minutes of break say 20m, it again fails for 1st time. I'm assuming that iOS is invalidating the cache on device regarding availability of appclip in store and hence the API call is made again and there is a delay and failure. can you please help us with this issue.

Screen Time can be bypassed by manually changing the date and time
My son uses an iPhone XS running iOS 18.7.2. He is able to bypass all Screen Time app limits by manually changing the date under Settings → General → Date & Time. When he sets the date/time forward or backward, the configured Screen Time restrictions no longer apply. Please make it possible on iOS 18.7.2 (and future versions) to prevent manual date and time changes when Screen Time is enabled, so that children cannot use this method to circumvent app limits.

Pass DeviceActivitySelection to DeviceActivityMonitorExt
Hi I'm trying to build a screen time app and the Apple docs and APIs really leave something to be desired. I want to block apps on a schedule. That's it. To do this I need my DeviceActivityMonitorExt to know which apps to block. I need to somehow pass a DeviceActivitySelection from the main app into this DeviceActivityMonitorExt. How can I do this?

Twilio Voice iOS SDK: callInvite is missing when accepting incoming call from CallKit or React Native
I'm integrating Twilio Voice (v6.12.1) into my React Native app (using Swift bridging for iOS) and have implemented full VoIP, PushKit, and CallKit support for incoming calls. ✅ What works: Incoming calls trigger the VoIP push and display the full-screen CallKit interface (or fallback UI). Decline Call works as expected. Call logs and events print correctly. ❌ Problem: When I try to accept the call using the CallKit Accept button or React Native fallback UI, I consistently get: ❌ [TwilioVoiceModule] answerCall() callInvite is missing. I also noticed that the console logs for answerCall() are being printed three times in a row, even though the accept button is only pressed once. Additionally in the first time console, answerCall() CallInvite found, accepting... 🔍 Observations: The callInvite is properly received when the VoIP push arrives. But when answerCall() is triggered, callInvite becomes nil. This happens in CallKit accept, RN UI accept, and even notification banner accept. 📦 How it's set up (summarized): PushKit Registration – via PKPushRegistry in AppDelegate.swift VoIP push handling – forwards payload to TwilioVoiceModule.handleIncomingPush() CallKit integration – uses CXProviderDelegate to report and handle accept actions JS Bridge – emits acceptCallAction to JS React Native calls TwilioVoiceModule.answerCall(uuid, callSid) In answerCall() method: self.callInvite is nil – so call cannot be accepted. Attaching the link to view the relevant code: https://docs.google.com/document/d/15pNjKrfk954OaotpMIEh3xQUtst---1K45DBXoYctGM/edit?usp=sharing 💡 Call Accept Flow (iOS): VoIP Push → TwilioVoiceModule.handleIncomingPush() Twilio SDK creates callInvite reportNewIncomingCall() triggers CallKit UI On accept: CXAnswerCallAction → emits event to JS RN calls TwilioVoiceModule.answerCall(uuid, callSid) Problem: callInvite is already nil ❓ What I'm trying to understand: Why is callInvite becoming nil before answerCall() is called? Why are the logs showing the answerCall() call 3 times? Is there a race condition or multiple accept triggers? Should I ensure callInvite is accepted only once across all 3 accept paths? ** 💬 Any help would be appreciated.** 📱 Environment: React Native 0.78.x iOS 17+ Swift bridging with TwilioVoiceModule.swift Twilio Voice SDK 6.12.1 PushKit + CallKit + react-native-callkeep

Testing iMessage extension from recipient POV
Hello, I am building an iMessage extension for my app and I am struggling to figure out how to test it. The extension allows users to send their friends an interactive widget and the recipient experience is very important to test. I tried to do it in the simulators, but simulators do not support iMessage. I have got a second iPhone and created a sandbox account, but I cannot install TestFlight with the sandbox account, as this feature is not supported. Reddit, Stackoverflow, ChatGPT and Apple Developer support also did not help. Can someone share their experience with testing recipient experience in the iMessage extension?

How to block large lists of domains (1000+) using Screen Time API?
I'm developing a parental control app that needs to block adult/18+ websites using the Screen Time API. I've run into scaling issues with 'ManagedSettings.webContent.blockedByFilter`. Environment: iOS 18.x, real device (iPhone) ManagedSettings framework Screen Time permissions granted Current Behavior: The Question: Commercial parental control apps successfully block tens of thousands of domains. What API or architecture should I be using to scale beyond 30-50 domains? Approaches I'm considering: Safari Content Blockers (limited to Safari only) Multiple ManagedSettingsStore instances Network Extension / DNS filtering A different Screen Time API approach What's the recommended way to block large domain lists (1000-60000+) across all apps and browsers? Any guidance appreciated! //33 domains - Works perfectly let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), WebDomain(domain: "example2.com"), // ... 31 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // All 33 domains blocked successfully // 101 domains - Complete failure (no domains blocked at all) let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), // ... 100 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // No errors thrown, but ZERO domains are blocked
