Crash (KERN_INVALID_ADDRESS) on IOS 26.2 GM when calling isEligibleForAgeFeatures
We recently released an update to our app to prepare for TX SB2420. Almost immediately on release, we started getting crash reports of crashes when calling isEligibleForAgeFeatures. Crashed: com.apple.root.user-initiated-qos.cooperative EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000004 Is it possible that these are beta users that have IOS 26.2 RC or is there a bug in the release version of IOS 26.2? Note: The crash reports are coming from Crashlytics so we are not getting OS build identifiers other than version "26.2"

SensorKit - Questions about the startRecording() and data holding period
From the document https://developer.apple.com/documentation/sensorkit/srfetchrequest we know that "SensorKit places a 24-hour holding period on newly recorded data before an app can access it. This gives the user an opportunity to delete any data they don’t want to share with the app. A fetch request doesn’t return any results if its time range overlaps this holding period." Will this holding period reset each time when I called startRecording() ? Let's say I upgrade my app to a new version, do I need to call startRecording again to init the data collection process? will it be able to query the data collected from previous version's app ?

AgeRange Assurance Testing and Texas Law
AgeRangeService is the burning topic right now. Needless to say, Everything is so unclear. We got our app finally into the TestFlight for QA and the product to test. only to find out that AgeAssurance for sandbox testing does not work. There is no document confirming or denying whether and when age assurance for the App with the release configuration in test flight would work. There isn't any guidance from Apple on whether an app that sells physical goods, such as an e-commerce app, can continue doing business as usual. Also, there is no clarity that the Age assurance options are off, 13, unverified, 13 verified, and so on. How those should be used.

Any way to adjust the speechRecognitionMetadata pause duration?
Speech Framework I've been checking for SFSpeechRecognitionMetadata to determine the end of a sentence when using Voice Recognition. Yet it doesn't detect small pauses but only large ones, so that I've transcribed basically an entire paragraph before going onto the next one. Besides implementing your own timer, are there any other ways to have more natural pauses to detect the end of sentences, similar to the browser's Web Speech recognition? Since it's in Safari, I assume there should be some similar feature that can be equivalent in MacOS.

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?

CarKeyRemoteControlSession always returning empty
We are developing an iOS app to connect to vehicles and trigger predefined vehicle controls (door lock/unlock) via the Digital Key framework. We are currently blocked on several aspects and would appreciate your expertise to clarify the following queries. How can we list down connected vehicle information? What is the method to retrieve connection status? How can we perform vehicle control actions (e.g., door lock/unlock)? STEPS TO REPRODUCE Starting the CarKeyRemoteControlSession to Fetch Vehicle Reports Currently, we are using the following API to start a CarKeyRemoteControlSession: open class func start( delegate: any CarKeyRemoteControlSessionDelegate, subscriptionRange subscriptionFunctionIDRange: ClosedRange? = nil, with delegateCallbackQueue: DispatchQueue? = nil ) async throws -> CarKeyRemoteControlSession After successfully creating the session, we check for vehicle reports using the vehicleReports property of CarKeyRemoteControlSession: public var vehicleReports: [VehicleReport] { get throws }

Is there a way to prevent the app from coming to the foreground when accepting a call with a banner-type call kit in a VoIP app?
I'm developing a VoIP app. Currently, I'm using CallKit to control call acceptance, and end-of-call processing. When a call comes in while using the phone, CallKit appears as a banner at the top of the screen. When I click "Accept" on the banner, the app opens and the call is received. (For OEMs, clicking the "Accept" button in the banner will accept the call as is.) The reason this feature is needed is, for example, when a call comes in as a banner call while using a navigation app, accepting the call causes the navigation app to go to the back and the VoIP app to come to the foreground, causing inconvenience to customers. This needs to be improved. Please advise.

Preparing your app to be the default calling app on iOS 18.2?
Hello, I’m working on a caller ID app and with the release of iOS 18.2, Apple has introduced the ability to set a third-party app as the default calling app. I have followed the official documentation for this feature and successfully set my app as the default phone app for making and receiving calls. Documentation Reference: https://developer.apple.com/documentation/callkit/preparing-your-app-to-be-the-default-calling-app Now, I’m facing some challenges and need some guidance: Custom UI for Incoming Cellular Calls: Is it possible to show a custom UI when receiving SIM-based cellular calls (not VoIP)? I want to replace the default iOS call screen with my own design when a cellular call is received. Can CallKit allow me to manage and display this custom UI for real cellular calls? Detecting Incoming Cellular Calls: Can I detect incoming SIM-based cellular calls when my app is set as the default calling app? I would like to track and show details of incoming calls (e.g., caller information, call duration) using a custom interface. Displaying Call Data (Call Duration, Recent Calls): Can I show call data (e.g., call duration, recent call history, etc.) for SIM-based cellular calls within my app when it is the default calling app? I need to know if it’s possible to retrieve and display this data in a custom format. Managing Outgoing Cellular Calls: For SIM-based outgoing calls, can I handle the process of initiating the call and then show a custom UI for the call in progress (similar to how VoIP apps manage outgoing calls)? I understand that CallKit can be used to manage the UI for calls, but I’m unsure about the limitations when it comes to real SIM-based cellular calls. Is it possible to implement these features with the current API capabilities, or are there any restrictions I should be aware of when managing cellular network calls? Thanks in advance for your help!

Clarification on AskCenter and Age Assurance APIs for Texas Regulatory Compliance
Hello, I’m currently reviewing and implementing age assurance and parental approval flows using AgeRangeService and PermissionKit (AskCenter) in the context of Texas regulatory compliance requirements. While the high-level APIs are clear, there are several technical aspects where the intended usage patterns are not fully explicit in the documentation. Clarification on these points would help ensure our implementation aligns with system expectations and regulatory obligations. ⸻ Querying the current approval state for SignificantAppUpdateTopic AskCenter.ask(...) returns Void, and AskCenter.responses(for:) provides an AsyncSequence of approval events. Is there an official or recommended way to determine whether a SignificantAppUpdateTopic has already been approved when the app launches, or is listening for future responses events the only supported mechanism? ⸻ Behavior of AskCenter.responses(for:) regarding past approvals When subscribing to AskCenter.responses(for:): • Does the stream replay previously recorded approval or decline decisions? • Or does it only emit events that occur after subscription? This affects whether the listener must be registered early in the app lifecycle. ⸻ Recommended lifecycle timing for registering a responses(for:) listener What is the intended or recommended time to register a responses(for:) listener? • At application launch • Immediately before calling ask(...) • When entering a specific gated feature Clarification on the expected lifecycle usage would be helpful. ⸻ Repeated calls to ask(...) after approval If AskCenter.ask(...) is called again for the same SignificantAppUpdateTopic after parental approval has already been granted: • Is the request ignored? • Is a new approval request sent to the parent? • Or is the call handled idempotently by the system? ⸻ Delivery of approval results when the child app is not running If a parent approves or declines a SignificantAppUpdateTopic while the child app is not running: • Will the approval decision be delivered as a responses(for:) event on the next app launch? • Or is the app expected to persist approval state locally? ⸻ Persistence of approval state Is the approval decision for SignificantAppUpdateTopic persisted by the system at the OS level, or is the app responsible for storing approval state? Additionally, does the approval persist across: • app restarts? • app deletion and reinstallation? ⸻ Meaning of activeParentalControls.significantAppChangeApprovalRequired How is activeParentalControls.significantAppChangeApprovalRequired determined? • Is this value explicitly configured by a parent (for example via Screen Time)? • Or is it automatically determined by the system based on region, age, or regulatory requirements? ⸻ Relationship between significantAppChangeApprovalRequired and AgeRangeService When activeParentalControls contains significantAppChangeApprovalRequired, is it still expected that apps call AgeRangeService.requestAgeRange(...)? Or can the presence of this flag be treated as sufficient indication that the user is a minor for gating purposes? ⸻ Recommended interpretation of AgeRangeDeclaration Is the intended usage of AgeRangeDeclaration to handle each case individually, or is it acceptable and recommended to interpret the values as different trust levels (for example, self-declared vs. government ID or payment verified)? Clarification on these points would help ensure that implementations of age assurance and parental approval flows are consistent with system behavior while meeting regulatory compliance requirements. Thank you for your guidance.

Contacts Framework CPU Loop (M1 Max / Exchange)
When syncing an Office 365 (Exchange) account on an M1 Max machine running the latest macOS (e.g., Sonoma), the native contactsd and AddressBookManager processes enter a severe, persistent failure loop. The CPU usage spikes from 0.0% to over 80% (observed at 81%) and repeats every 60-90 seconds. This occurs even when the account is entirely empty of contacts and after performing a clean macOS installation, strongly indicating a systemic bug in the framework's Exchange protocol handler on the M1 architecture. System Information Affected Hardware: Apple M1 Max Affected macOS Version: Tahoe 26.1 Affected Processes: contactsd, AddressBookManager Account Type: Microsoft Exchange / Office 365 Steps to Reproduce System Setup: Perform a clean installation of macOS on the M1 Max machine (USB boot, NO Migration Assistant or data restoration). Account Preparation: Ensure the target Exchange account's contacts folder is entirely empty on the server (via Outlook Web Access). Trigger: Go to System Settings > Internet Accounts and add the Exchange account. Ensure ONLY Contacts is toggled ON. Observation: Open Activity Monitor and sort by % CPU. Expected Behavior The contactsd and AddressBookManager processes should spike briefly (under 5%) to establish the empty sync, then settle to a persistent idle state (0.0% to 0.5% CPU). Actual Behavior The processes never settle: CPU Spikes: Usage repeatedly jumps from 0.0% to 81% for AddressBookManager and 22-59% for contactsd. Pattern: This extreme spike lasts for a few seconds before the thread crashes/restarts, and the process immediately re-initiates the loop, consuming massive CPU cycles continuously. Diagnostic Proof The runaway CPU is not caused by corrupt data: Data Neutralization: The account's contacts folder was emptied on the server, yet the high CPU loop persisted when syncing. Clean System: The issue is reproducible on a clean, from-scratch macOS installation, ruling out corrupted user preferences or system files. Cross-Architecture: The exact same account syncs perfectly on iOS and newer M4 Macs, confirming the data is valid and the issue is specific to the M1 Max's implementation of the Exchange protocol handler. Workaround (For Visibility) To restore system performance, the user must DELETE the entire Exchange account from System Settings > Internet Accounts and use a third-party client (e.g., Outlook for Mac) for synchronization, as it bypasses the buggy native framework.

Extract raw Screen Time data? Security says it's 'expected'
Hi everyone, I have a question regarding the intended privacy limits of the DeviceActivityReportExtension. According to the documentation and the WWDC21 session "Meet the Screen Time API", this extension was created specifically to prevent the host application from accessing the user's underlying activity data (websites visited, app usage, screen time, etc). But I have found that my host app is actually able to reconstruct this raw activity data from the activity report. I am able to extract specific visited websites and app usage durations back into the main app. I reported this to Apple Security (Case ID: OE1100504480881 ), assuming it was a sandbox bypass. However, they closed the ticket stating that this is "expected behavior" and requires no fix. My question for Screen Time Engineers: Is the documentation incorrect? If my host app is expected to be able to read this data, is there a formal API we should be using instead of extracting it from the report extension? The current behavior contradicts the privacy limits described in the documentation, so I am confused if I should rely on this data access for my app features or if it will be patched later. Thanks.

How to identify which minor user's authorization has been revoked by the parent/guardian?
I followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged): { "receiptType": "Sandbox", "bundleId": "com.xxx.xxxxx", "receiptCreationDate": 1764932591296, "requestDate": 1764932591296, "originalPurchaseDate": 1375340400000, "originalApplicationVersion": "1.0", "appTransactionId": "705020051250081000", "originalPlatform": "iOS" } How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app. I hope to receive a prompt response from Apple's technical experts! Thanks A Lot !

iOS 26: Unable to Transition from CallKit Screen to App when remoteHandle is nil or empty string
Hello, I am developing an internal phone application using CallKit. I am experiencing an issue with the behavior of remoteHandle settings in iOS 26 and would appreciate any insights you can provide towards a solution. 1. Problem Description When an iPhone running iOS 26 is in a sleep state and receives a VoIP incoming call where remoteHandle is set to nil or an empty string (@""), we are unable to transition to our application (the UIExtension provided by the provider) from the CallKit UI's "More" (…) button after answering the call. 2. Conditions and Symptoms OS Version: iOS 26 Initial State: iPhone is in a sleep state Call Type: An unsolicited(unknown number) VoIP incoming call where the CXCallUpdate's remoteHandle is set to either nil or [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""] Symptoms: After answering the VoIP call by sliding the button, selecting the "More" (…) button displayed on the CallKit screen does not launch our application's UIExtension (custom UI), and the iPhone instead stay to the CallKit screen. 3. Previous Behavior (Up to iOS 18) Up to iOS 18, even when remoteHandle was set to an empty string using the following code, the application would transition normally from "More" after answering an incoming call from a sleep state. CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@""]; [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 4. Unsuccessful Attempts to Resolve The issue remained unresolved after changing the handling for unsolicited(unknown number) incoming calls as follows: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = nil; // Set remoteHandle to nil [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 5. Workaround (Temporary) The problem can be resolved, and the application can transition successfully, by setting a dummy numerical value (e.g., "0") for the value in remoteHandle using the following code: CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.remoteHandle = [[CXHandle alloc] initWithType:CXHandleTypePhoneNumber value:@"0"]; // Set a dummy numerical value [provider reportNewIncomingCallWithUUID:uuid update:update completion:completion]; 6. Additional Information If remoteHandle is correctly set with the caller's number (i.e., not an unsolicited(unknown number) call; e.g., value:@"1234567890"), the application transitions normally from the "More" button after answering an incoming call from a sleep state, even in iOS 26. The above issue does not occur when answering incoming calls while the iPhone is in an active state (not sleeping). 7. Questions Have there been any other reports of similar behavior? Should this be considered a bug in CallKit for iOS 26? Should I make file a new Feedback report? Is there a suitable method to resolve this issue when the caller ID is unsolicited (nil or an empty string)? This problem significantly impacts user operations as end-users are unable to perform essential in-app actions such as hold or transfer after answering an unsolicited(unknown number) call from a sleep state. We are eager to find an urgent solution and would appreciate any information or advice you can provide. Thank you for your assistance.

CallKit Keeps Terminating
Hello, I am currently developing a call service using CallKit and VoIP push. Recently, I have encountered a very challenging issue. During testing, when a VoIP push is received, the incomingCall gets triggered continuously, but then it automatically terminates after about 1-2 seconds. I am checking this issue under the debug scheme, and even when switching to different commits, the same problem persists. I suspect it might be an issue with the device, but I would like to confirm the cause and find a solution. Below are some characteristics I have noticed: On this device, when a VoIP push is received, CallKit automatically terminates, but this does not occur when debugging. The issue always occurs when not debugging. Looking at the device console logs related to callservicesd, there are many logs with 'invalidate' appended. For example: Invalidating process assertion for bundle ID from timeout All calls ended. Clearing system uplink muted cache Invalidate callDurationUpdateTimer InCallService has changed process state to 2 InCallService has been suspended; invalidating its XPC client connections. [0x565544180] invalidated because the current process cancelled the connection by calling xpc_connection_cancel() XPC connection invalidated from client These logs appear although our server did not receive any incoming call request, so we did not terminate it on our end. I also checked if there was a crash, but there were no reports left on the device. Could you please share any insights into the cause or solutions for this situation? Thank you.

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!

blockedApplications api to HIDE app categories?
Is there any way to use blockedApplications to hide all apps in a category? Currently, I use blockedApplications to hide individual apps, but it doesn’t work when I select an entire category. I thought the only solution would be to use shield, which doesn’t hide the apps but creates a blocking shield. However, I found an app on the App Store called Fokus, and it’s able to select a category and block all the apps in it. Does anyone know how this could be possible?

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!
