IsEligibleForAgeFeatures behavior in Brazil
From the Feb 24 news, I understand that for all Apple users in Brazil with iOS26.2 and newer, isEligibleForAgeFeatures will eventually return true. Brazil is a "nonregulated region", and developers will need to handle all three situations of ask first/always share/never share. Please correct me if I'm wrong above. A few questions follow on the eligibility check: What's the return value of IsEligibleForAgeFeatures for a Brazilian user who has NOT touched the age range feature at all, thus hasn't picked one of the three options? How can we test these cases? From the updated sandbox doc, there's more information on declined/approved, will those the same behaviors as a future Brazilian user? The doc used to say Texas, now it doesn't say any region. On which date will Apple START to return true for IsEligibleForAgeFeatures for Brazilian users? I cannot find the exact date anywhere. Will ALL of Brazil return true overnight, or is there some ramp up that developers need to be aware of? Thanks a lot for sharing the guidance, and thanks in advance for more guidance to come!

CloudKit: Efficient way to get user's rank in leaderboard without fetching all records?
CloudKit: Efficient way to get user's rank in leaderboard without fetching all records? I'm building a leaderboard feature using CloudKit's public database and need advice on the best approach to calculate a user's rank efficiently. Current Setup Record Structure: Record Type: LeaderboardScore Fields: period (String): "daily", "weekly", "monthly", "allTime" score (Int): User's score profile (Reference): Link to user's profile achievedAt (Date): Timestamp Leaderboard Display: Initially fetch first 15 users (sorted by score descending) Paginate to load more as user scrolls Show total player count Show current user's rank (even if not in top 15) The Challenge I can fetch the first 15 users easily with a sorted query, but I need to display the current user's rank regardless of their position. For example: User could be ranked #1 (in top 15) ✅ Easy User could be ranked #247 (not in top 15) ❌ How to get this efficiently? My Current Approach Query records with scores higher than the user's score and count them: // Count how many users scored higher let predicate = NSPredicate( format: "period == %@ AND score > %d", period, userScore ) // Rank = count + 1 Concerns For 1000+ users with better scores, this requires multiple paginated queries Even with desiredKeys: [], I'm concerned about performance and CloudKit request limits Questions Is there a CloudKit API I'm missing that can efficiently count records matching a predicate without fetching all the records and paginating? Is this approach acceptable for a leaderboard with 1K-10K users? Does fetching with desiredKeys: [] help significantly with performance? Are there any optimizations I should consider to make this more efficient? What's the recommended approach for calculating user rank in CloudKit at this scale? Current Scale Expected: 1,000-10,000 active users per leaderboard period Platform: iOS 17+, SwiftUI Any guidance on best practices for leaderboards usecase in CloudKit would be greatly appreciated!

isEligibleForAgeFeatures and different legal requirements for different regions
https://developer.apple.com/documentation/DeclaredAgeRange/AgeRangeService/isEligibleForAgeFeatures returns a bool. I assume that means that it will return True for the states where their laws are in effect. The TX law and the UT/LA/AZ laws have different requirements though: TX requires the app verify the user's age on every app launch. These other states require the app verify the user's age "no more than once during each 12-month period" A future law (Brazil maybe?) might do something else. How can we determine if the user is eligible for the TX versus other state requirements?

Expected behavior of searchDomains
Based on https://developer.apple.com/documentation/networkextension/nednssettings/searchdomains , we expect the values mentioned in searchDomains to be appended to a single label DNS query. However, we are not seeing this behavior. We have a packetTunnelProvider VPN, where we set searchDomains to a dns suffix (for ex: test.com) and we set matchDomains to applications and suffix (for ex: abc.com and test.com) . When a user tries to access https://myapp , we expect to see a DNS query packet for myapp.test.com . However, this is not happening when matchDomainsNoSearch is set to true. https://developer.apple.com/documentation/networkextension/nednssettings/matchdomainsnosearch When matchDomainsNoSearch is set to false, we see dns queries for myapp.test.com and myapp.abc.com. What is the expected behavior of searchDomains?

copyfile Sometimes Fails to copy .DS_Store when Copying a Folder But Does Not Report Usable Error
Testing copyfile on a folder on an external volume (which takes a bit a of time) I'm running into an issue where copyfile gets to the end of the operation and then just fails. In the callback I can see that the failure occurs on a .DS_Store file inside the folder. So for a .DS_Store it is simple enough for me to just ignore the error and return COPYFILE_SKIP but the somewhat more concerning issue here is that the true error reason is seemingly not reported? In the callback if I read errno it is 0. When copyfile returns it returns -1 after I return COPYFILE_QUIT (and errno is 0) so I don't know what the error is or the appropriate way to handle it. For .DS_Store just skipping seems reasonable but when copying a folder it may be appropriate to get the true failure reason. But checking the last path component of source path seems like a hack way to handle errors. If a file in the copying folder with important user data I can't just silently skip it - it isn't clear to me how I should properly proceed in a situation where I can't get the actual reason for the failure.

Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems
This is a bit complicated to explain so bare with me. I am working on building an app that allows you to send real time video/camera captures from one Apple device to another. I am using a custom UDP protocol built on top of NWListener, NWBrowser, and NWConnection APIs. It works fine, but there are a few issues that seems to all be related to awdl: When transmitting via WiFi over the router (not using peer-to-peer), there are periodic interruptions when the wireless card on the device changes channels for awdl polling. This is resolved by changing the 5GHz WiFi channel on the router to channel 149 (or disabling AWDL altogether which is not really feasible). In order to work around number 1, I decided to build in an option to toggle/prefer peer-to-peer transmission in the app thinking that if everything goes over a peer-to-peer connection the jitter caused from the channel switching should go away. This also works, but with an important caveat. The default transmission is extremely choppy until you take an OS action that “elevates” the AWDL connection into “realtime” mode. I am using includePeerToPeer on the listener, browser, and connection as well as serviceClass interactiveVideo. For number 1, you can understand that asking users to change the channel on their router is not a great user experience, but the problem is the peer-to-peer connection workaround is also not great by default. For number 2, as an example of the behavior, I can send a stream from my Mac to my iPad over a peer-to-peer connection and it works but the video is very choppy until I move my cursor from my Mac to my iPad to trigger Universal Control. I captured the OS logs while doing this and can confirm that something happens to trigger “realtime” mode on the AWDL connection. After that, the streaming is totally smooth with zero latency.

I have already tried a lot of things, but is there any way to programmatically trigger “realtime” mode? For additional context, the goal here is to have extremely low latency that also works for gaming. The actual latency introduced in 1 is approximately 30-50ms around once a second… adding a buffer to the stream makes the video completely smooth, but the extra delay on the receiver end is not acceptable for this use case. Any help or ideas would be appreciated. I can’t easily share a reproduce case right now, and even if I could, getting multiple devices into the exact state along with the router configuration in order to reproduce is going to be pretty difficult anyway.

Apple Server Notifications Webhooks stopped retrying on HTTP 400
Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!

Getting a basic URL Filter to work
I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

AlarmKit leaves an empty zombie Live Activity in Dynamic Island after swipe-dismiss while unlocked
Hi, We are the developers of Morning Call (https://morningcall.info), and we believe we may have identified an AlarmKit / system UI bug on iPhone. We can reproduce the same behavior not only in our app, but also in Apple’s official AlarmKit sample app, which strongly suggests this is a framework or system-level issue rather than an app-specific bug. Demonstration Video of producing zombie Live Activity https://www.youtube.com/watch?v=cZdF3oc8dVI Related Thread https://developer.apple.com/forums/thread/812006 https://developer.apple.com/forums/thread/817305 https://developer.apple.com/forums/thread/807335 Environment iPhone with Dynamic Island Alarm created using AlarmKit Device is unlocked when the alarm begins alerting Steps to reproduce Schedule an AlarmKit alarm. Wait for the alarm to alert while the device is unlocked. The alarm appears in Dynamic Island. Instead of tapping the intended stop or dismiss button, swipe the Dynamic Island presentation away. Expected result The alarm should be fully dismissed. The Live Activity should be removed. No empty UI should remain in Dynamic Island. Actual result The assigned AppIntent runs successfully. Our app code executes as expected. AlarmKit appears to stop the alarm correctly. However, an empty “zombie” Live Activity remains in Dynamic Island indefinitely. The user cannot clear it through normal interaction. Why this is a serious user-facing issue This is not just a cosmetic issue for us. From the user’s perspective, it looks like a Live Activity is permanently stuck in Dynamic Island. More importantly: Force-quitting the app does not remove it Deleting the app does not remove it In practice, many users conclude that our app has left a broken Live Activity running forever We receive repeated user complaints saying that the Live Activity “won’t go away” Because the remaining UI appears to be system-owned, users often do not realize that the only reliable recovery is to restart the phone. Most users do not discover that workaround on their own, so they instead assume the app is severely broken. Cases where the zombie state disappears Rebooting the phone Waiting for the next AlarmKit alert, then pressing the proper stop button on that alert Additional observations Inside our LiveActivityIntent, calling AlarmManager.shared.stop(id:) reports that the alarm has already been stopped by the system. We also tried inspecting Activity<AlarmAttributes<...>>.activities and calling end(..., dismissalPolicy: .immediate), but in this state no matching activity is exposed to the app. This suggests that the alarm itself has already been stopped, but the system-owned Live Activity UI is not being cleaned up correctly after the swipe-dismiss path. Why this does not appear to be an app logic issue The intent is invoked successfully. The alarm stop path is reached. The alarm is already considered stopped by the system. The remaining UI appears to be system-owned. The stuck UI persists even after our own cleanup logic has run. The stuck UI also survives app force-quit and app deletion.

AlarmKit sometimes creates a blank (empty) Live Activity
Hi! My users have reported (and I have observed) a blank Live Activity where only a black capsule is shown in the dynamic island. When tapping that capsule, the app opens, but inside the capsule, nothing is shown. The Live Activity is created through the AlarmKit API like this: let identifier = UUID() Task { do { _ = try await AlarmManager.shared.schedule( id: identifier, configuration: .init( countdownDuration: countdownDuration, attributes: attributes, stopIntent: CancelTimerIntent(), secondaryIntent: RestartTimerIntent(), sound: Settings.shared.systemAlarmToneEnabled ? .default : .named(Settings.shared.alarmTone[.loop].filename) ) ) Log.debug("Alarm scheduled successfully: \(identifier.uuidString)") } catch { Log.error("Error scheduling alarm with id \(identifier.uuidString), error: \(error)") } } I've read some other forum posts where developers reported the same issue: https://developer.apple.com/forums/thread/807335 https://developer.apple.com/forums/thread/812006 I assume, it has something to do with state management. However, in my case, this only happens very rarely. I use the app on a daily basis and the issue with the blank live activity only occurs like once a month, so I cannot reproduce it. I also have some logic to resume an existing alarm or snooze: do { for alarm in try AlarmManager.shared.alarms { switch alarm.state { case .paused: try AlarmManager.shared.resume(id: alarm.id) case .alerting: try AlarmManager.shared.countdown(id: alarm.id) default: break } } } catch { Log.error("Error resuming alarm: \(error)") } Is there any way I can debug this issue properly? I have checked the Device Logs and the Console in Xcode and didn't find any hints. Only one log made me a little suspicious, but I read that this might happen occasionally and may be ignored: Couldn't read values in CFPrefsPlistSource<0x10ae0d080> (Domain: group.myappgroupidentifier User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd Any ideas on how I could proceed to find the cause of this empty (apparently crashed) Live Activity?

iOS26.4,appStoreReceiptURL获取票据延迟
iOS 26.4系统上,我们发现三个问题: 1.调用了finishTransaction接口,但是在App重新启动后,[SKPaymentQueue defaultQueue].transactions仍然会有这笔订单。 2.支付完成后,[[NSBundle mainBundle] appStoreReceiptURL]],拿到的票据解析出来里面的商品是空的,需要延迟2秒钟左右在调用[[NSBundle mainBundle] appStoreReceiptURL]]才能获取有效票据。 3.支付完成后,如果用户没有点击最后弹出的确认弹框,等待5秒钟,系统会自己回调 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions; 代理方法。正常应该是用户点击了最后弹出的确认弹框,在回调- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions;方法。 我们在苹果开发者论坛上面找到其他开发者反馈的类似问题,链接如下: https://developer.apple.com/forums/thread/817700 https://developer.apple.com/forums/thread/792437?answerId=849557022#849557022 https://developer.apple.com/forums/thread/817834 https://developer.apple.com/forums/thread/817706 https://developer.apple.com/forums/thread/818586 我们有大量用户升级到了26.4系统,这对于我们造成了巨大的困扰,我们需要你们的帮助,感谢!

CXCallUpdate not working for outgoing calls
I try to update remoteHandle using CXCallUpdate for outgoing call, but this works only on iOS 15 but not on 17 or 18 (16 didn't test). This problem actual only for outgoing calls, but for incoming calls update works fine. func startOutgoingCall(with callID: UUID, userID: String) { let handle = CXHandle(type: .generic, value: userID) let action = CXStartCallAction(call: callID, handle: handle) callController.requestTransaction(with: action) { [weak self] error in // ... } } func updateOutgoingCall(with callID: UUID, groupID: String) { let update = CXCallUpdate() update.remoteHandle = CXHandle(type: .generic, value: groupID) provider.reportCall(with: callID, updated: update) } I also tried phoneNumber type but it seems initial handle that I set to CXStartCallAction not possible to change (value or even type). I use this handle value to implement recall by tap on call in Recents tab of system address book. But since my calls can transform from p2p to group call, I need to update handle value or find some another way to pass call identification info.

"appAccountToken" mismatched in sandbox environment
We're seeing some strange behavior of the appAccountToken when passing it to a purchase in the sandbox environment. Normally we'd expect the same account token to be set on the resulting verfication, but that's not the case. Instead the token seems to be persisted on the API side and reused for some amount of time, meaning there's a mismatch and the connection between account and purchase is lost. This happens consistently even if we send new tokens on each purchase. Has there been any updates to purchase flow in the sandbox environment on Apple's side? .purchase( options: [.appAccountToken(token)] )

HealthKit is currently not supported on macOS nor tvOS, despite being supported by visionOS. Support for macOS was last asked about[1] here in 2018. My goal is to display interactive data visualisations over workouts collected in HealthKit on macOS. Will this be possible to do in the near future using HealthKit directly? If not, can I somehow read the information from an iPhone and display it on the mac? Cheers, Rodrigo [1] https://developer.apple.com/forums/thread/94937

Different transaction IDs for the same purchase between SKPaymentTransaction and receipt latest_receipt_info
Hello, I am investigating a case where two different transaction IDs appear to refer to the same purchase, and I would like clarification on whether this behavior is expected. Additional context StoreKit version: StoreKit 1 (SKPaymentTransaction) Environment: Production Product type: Auto-renewable subscription Transaction sources The values are obtained from the following APIs: transaction_id from SKPaymentTransaction https://developer.apple.com/documentation/storekit/skpaymentqueue receipt_data from the App Store receipt https://developer.apple.com/documentation/foundation/bundle/appstorereceipturl Observed behavior After an In-App Purchase completes, the app receives: a transaction_id from SKPaymentTransaction the corresponding receipt_data for the purchase When inspecting the receipt, the transaction_id inside latest_receipt_info differs from the transaction_id received directly from the purchase transaction. For clarity: A = transaction_id received from the purchase flow (SKPaymentTransaction) A' = transaction_id found in receipt_data.latest_receipt_info The two values are different, but they differ only by 1. Additional observation The original_transaction_id for A and A' is identical, which suggests that both transaction IDs belong to the same subscription purchase chain. Pattern observation on the ID difference We have observed that the difference between A and A' is consistently exactly 1 (i.e., A' = A + 1) across multiple transactions, not just a single case. This appears to be a reproducible pattern rather than a coincidence. This observation raises an additional question (Question 6 below). API verification When calling: GET /inApps/v1/transactions/{transactionId} Both A and A' return what appears to be the same purchase record. The response data is effectively identical except for the transactionId field. However, when calling: GET /inApps/v2/history/{transactionId} A does not appear in the transaction history only A' appears in the history response Questions If A does not appear in transaction history, where does this transaction ID originate from? Why does Get Transaction Info (/inApps/v1/transactions/{transactionId}) return a valid response for A even though it is not present in the transaction history? Why do A and A' both resolve to what appears to be the same purchase? In this situation, which transaction ID should be treated as the canonical transaction ID for server-side validation? Is this difference related to how StoreKit 1 (SKPaymentTransaction) and the App Store Server API represent transactions? Is the consistent off-by-one difference between the transaction_id from SKPaymentTransaction and the one recorded in latest_receipt_info an intentional behavior of StoreKit 1's internal transaction ID assignment? Specifically, we are wondering whether StoreKit 1 applies some form of internal offset when delivering the transaction ID to the client, while the App Store server records a different (adjacent) ID in the receipt. If so, is this documented anywhere? Note We are currently in the process of migrating to StoreKit 2, but this behavior was observed while investigating our existing StoreKit 1 implementation. Any clarification would help us better understand the correct transaction model during the migration.

How to cancel Auto-renewable subscription bought in TestFlight?
I've read several topics on cancelling subscriptions in sandbox environment, but it seems to me that it could not be applied to TestFlight. I can cancel sandbox subscriptions through Settings > App Store > Sandbox account But since TestFlight does not use sandbox account I cannot cancel a sub from there. Also, TF purchase does not appear in the list of regular subscriptions (Settings > Profile > Media & Purchases). So my question is: is there any way to manually cancel auto-renewable subscription bought in TestFlight build of the app?

IsEligibleForAgeFeatures behavior in Brazil
From the Feb 24 news, I understand that for all Apple users in Brazil with iOS26.2 and newer, isEligibleForAgeFeatures will eventually return true. Brazil is a "nonregulated region", and developers will need to handle all three situations of ask first/always share/never share. Please correct me if I'm wrong above. A few questions follow on the eligibility check: What's the return value of IsEligibleForAgeFeatures for a Brazilian user who has NOT touched the age range feature at all, thus hasn't picked one of the three options? How can we test these cases? From the updated sandbox doc, there's more information on declined/approved, will those the same behaviors as a future Brazilian user? The doc used to say Texas, now it doesn't say any region. On which date will Apple START to return true for IsEligibleForAgeFeatures for Brazilian users? I cannot find the exact date anywhere. Will ALL of Brazil return true overnight, or is there some ramp up that developers need to be aware of? Thanks a lot for sharing the guidance, and thanks in advance for more guidance to come!

CloudKit: Efficient way to get user's rank in leaderboard without fetching all records?
CloudKit: Efficient way to get user's rank in leaderboard without fetching all records? I'm building a leaderboard feature using CloudKit's public database and need advice on the best approach to calculate a user's rank efficiently. Current Setup Record Structure: Record Type: LeaderboardScore Fields: period (String): "daily", "weekly", "monthly", "allTime" score (Int): User's score profile (Reference): Link to user's profile achievedAt (Date): Timestamp Leaderboard Display: Initially fetch first 15 users (sorted by score descending) Paginate to load more as user scrolls Show total player count Show current user's rank (even if not in top 15) The Challenge I can fetch the first 15 users easily with a sorted query, but I need to display the current user's rank regardless of their position. For example: User could be ranked #1 (in top 15) ✅ Easy User could be ranked #247 (not in top 15) ❌ How to get this efficiently? My Current Approach Query records with scores higher than the user's score and count them: // Count how many users scored higher let predicate = NSPredicate( format: "period == %@ AND score > %d", period, userScore ) // Rank = count + 1 Concerns For 1000+ users with better scores, this requires multiple paginated queries Even with desiredKeys: [], I'm concerned about performance and CloudKit request limits Questions Is there a CloudKit API I'm missing that can efficiently count records matching a predicate without fetching all the records and paginating? Is this approach acceptable for a leaderboard with 1K-10K users? Does fetching with desiredKeys: [] help significantly with performance? Are there any optimizations I should consider to make this more efficient? What's the recommended approach for calculating user rank in CloudKit at this scale? Current Scale Expected: 1,000-10,000 active users per leaderboard period Platform: iOS 17+, SwiftUI Any guidance on best practices for leaderboards usecase in CloudKit would be greatly appreciated!

isEligibleForAgeFeatures and different legal requirements for different regions
https://developer.apple.com/documentation/DeclaredAgeRange/AgeRangeService/isEligibleForAgeFeatures returns a bool. I assume that means that it will return True for the states where their laws are in effect. The TX law and the UT/LA/AZ laws have different requirements though: TX requires the app verify the user's age on every app launch. These other states require the app verify the user's age "no more than once during each 12-month period" A future law (Brazil maybe?) might do something else. How can we determine if the user is eligible for the TX versus other state requirements?

Expected behavior of searchDomains
Based on https://developer.apple.com/documentation/networkextension/nednssettings/searchdomains , we expect the values mentioned in searchDomains to be appended to a single label DNS query. However, we are not seeing this behavior. We have a packetTunnelProvider VPN, where we set searchDomains to a dns suffix (for ex: test.com) and we set matchDomains to applications and suffix (for ex: abc.com and test.com) . When a user tries to access https://myapp , we expect to see a DNS query packet for myapp.test.com . However, this is not happening when matchDomainsNoSearch is set to true. https://developer.apple.com/documentation/networkextension/nednssettings/matchdomainsnosearch When matchDomainsNoSearch is set to false, we see dns queries for myapp.test.com and myapp.abc.com. What is the expected behavior of searchDomains?

copyfile Sometimes Fails to copy .DS_Store when Copying a Folder But Does Not Report Usable Error
Testing copyfile on a folder on an external volume (which takes a bit a of time) I'm running into an issue where copyfile gets to the end of the operation and then just fails. In the callback I can see that the failure occurs on a .DS_Store file inside the folder. So for a .DS_Store it is simple enough for me to just ignore the error and return COPYFILE_SKIP but the somewhat more concerning issue here is that the true error reason is seemingly not reported? In the callback if I read errno it is 0. When copyfile returns it returns -1 after I return COPYFILE_QUIT (and errno is 0) so I don't know what the error is or the appropriate way to handle it. For .DS_Store just skipping seems reasonable but when copying a folder it may be appropriate to get the true failure reason. But checking the last path component of source path seems like a hack way to handle errors. If a file in the copying folder with important user data I can't just silently skip it - it isn't clear to me how I should properly proceed in a situation where I can't get the actual reason for the failure.

Triggering “realtime” mode for peer-to-peer WiFi via awdl to fix jitter problems
This is a bit complicated to explain so bare with me. I am working on building an app that allows you to send real time video/camera captures from one Apple device to another. I am using a custom UDP protocol built on top of NWListener, NWBrowser, and NWConnection APIs. It works fine, but there are a few issues that seems to all be related to awdl: When transmitting via WiFi over the router (not using peer-to-peer), there are periodic interruptions when the wireless card on the device changes channels for awdl polling. This is resolved by changing the 5GHz WiFi channel on the router to channel 149 (or disabling AWDL altogether which is not really feasible). In order to work around number 1, I decided to build in an option to toggle/prefer peer-to-peer transmission in the app thinking that if everything goes over a peer-to-peer connection the jitter caused from the channel switching should go away. This also works, but with an important caveat. The default transmission is extremely choppy until you take an OS action that “elevates” the AWDL connection into “realtime” mode. I am using includePeerToPeer on the listener, browser, and connection as well as serviceClass interactiveVideo. For number 1, you can understand that asking users to change the channel on their router is not a great user experience, but the problem is the peer-to-peer connection workaround is also not great by default. For number 2, as an example of the behavior, I can send a stream from my Mac to my iPad over a peer-to-peer connection and it works but the video is very choppy until I move my cursor from my Mac to my iPad to trigger Universal Control. I captured the OS logs while doing this and can confirm that something happens to trigger “realtime” mode on the AWDL connection. After that, the streaming is totally smooth with zero latency.

I have already tried a lot of things, but is there any way to programmatically trigger “realtime” mode? For additional context, the goal here is to have extremely low latency that also works for gaming. The actual latency introduced in 1 is approximately 30-50ms around once a second… adding a buffer to the stream makes the video completely smooth, but the extra delay on the receiver end is not acceptable for this use case. Any help or ideas would be appreciated. I can’t easily share a reproduce case right now, and even if I could, getting multiple devices into the exact state along with the router configuration in order to reproduce is going to be pretty difficult anyway.

Apple Server Notifications Webhooks stopped retrying on HTTP 400
Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!

Getting a basic URL Filter to work
I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

AlarmKit leaves an empty zombie Live Activity in Dynamic Island after swipe-dismiss while unlocked
Hi, We are the developers of Morning Call (https://morningcall.info), and we believe we may have identified an AlarmKit / system UI bug on iPhone. We can reproduce the same behavior not only in our app, but also in Apple’s official AlarmKit sample app, which strongly suggests this is a framework or system-level issue rather than an app-specific bug. Demonstration Video of producing zombie Live Activity https://www.youtube.com/watch?v=cZdF3oc8dVI Related Thread https://developer.apple.com/forums/thread/812006 https://developer.apple.com/forums/thread/817305 https://developer.apple.com/forums/thread/807335 Environment iPhone with Dynamic Island Alarm created using AlarmKit Device is unlocked when the alarm begins alerting Steps to reproduce Schedule an AlarmKit alarm. Wait for the alarm to alert while the device is unlocked. The alarm appears in Dynamic Island. Instead of tapping the intended stop or dismiss button, swipe the Dynamic Island presentation away. Expected result The alarm should be fully dismissed. The Live Activity should be removed. No empty UI should remain in Dynamic Island. Actual result The assigned AppIntent runs successfully. Our app code executes as expected. AlarmKit appears to stop the alarm correctly. However, an empty “zombie” Live Activity remains in Dynamic Island indefinitely. The user cannot clear it through normal interaction. Why this is a serious user-facing issue This is not just a cosmetic issue for us. From the user’s perspective, it looks like a Live Activity is permanently stuck in Dynamic Island. More importantly: Force-quitting the app does not remove it Deleting the app does not remove it In practice, many users conclude that our app has left a broken Live Activity running forever We receive repeated user complaints saying that the Live Activity “won’t go away” Because the remaining UI appears to be system-owned, users often do not realize that the only reliable recovery is to restart the phone. Most users do not discover that workaround on their own, so they instead assume the app is severely broken. Cases where the zombie state disappears Rebooting the phone Waiting for the next AlarmKit alert, then pressing the proper stop button on that alert Additional observations Inside our LiveActivityIntent, calling AlarmManager.shared.stop(id:) reports that the alarm has already been stopped by the system. We also tried inspecting Activity<AlarmAttributes<...>>.activities and calling end(..., dismissalPolicy: .immediate), but in this state no matching activity is exposed to the app. This suggests that the alarm itself has already been stopped, but the system-owned Live Activity UI is not being cleaned up correctly after the swipe-dismiss path. Why this does not appear to be an app logic issue The intent is invoked successfully. The alarm stop path is reached. The alarm is already considered stopped by the system. The remaining UI appears to be system-owned. The stuck UI persists even after our own cleanup logic has run. The stuck UI also survives app force-quit and app deletion.

AlarmKit sometimes creates a blank (empty) Live Activity
Hi! My users have reported (and I have observed) a blank Live Activity where only a black capsule is shown in the dynamic island. When tapping that capsule, the app opens, but inside the capsule, nothing is shown. The Live Activity is created through the AlarmKit API like this: let identifier = UUID() Task { do { _ = try await AlarmManager.shared.schedule( id: identifier, configuration: .init( countdownDuration: countdownDuration, attributes: attributes, stopIntent: CancelTimerIntent(), secondaryIntent: RestartTimerIntent(), sound: Settings.shared.systemAlarmToneEnabled ? .default : .named(Settings.shared.alarmTone[.loop].filename) ) ) Log.debug("Alarm scheduled successfully: \(identifier.uuidString)") } catch { Log.error("Error scheduling alarm with id \(identifier.uuidString), error: \(error)") } } I've read some other forum posts where developers reported the same issue: https://developer.apple.com/forums/thread/807335 https://developer.apple.com/forums/thread/812006 I assume, it has something to do with state management. However, in my case, this only happens very rarely. I use the app on a daily basis and the issue with the blank live activity only occurs like once a month, so I cannot reproduce it. I also have some logic to resume an existing alarm or snooze: do { for alarm in try AlarmManager.shared.alarms { switch alarm.state { case .paused: try AlarmManager.shared.resume(id: alarm.id) case .alerting: try AlarmManager.shared.countdown(id: alarm.id) default: break } } } catch { Log.error("Error resuming alarm: \(error)") } Is there any way I can debug this issue properly? I have checked the Device Logs and the Console in Xcode and didn't find any hints. Only one log made me a little suspicious, but I read that this might happen occasionally and may be ignored: Couldn't read values in CFPrefsPlistSource<0x10ae0d080> (Domain: group.myappgroupidentifier User: kCFPreferencesAnyUser, ByHost: Yes, Container: (null), Contents Need Refresh: Yes): Using kCFPreferencesAnyUser with a container is only allowed for System Containers, detaching from cfprefsd Any ideas on how I could proceed to find the cause of this empty (apparently crashed) Live Activity?

iOS26.4,appStoreReceiptURL获取票据延迟
iOS 26.4系统上,我们发现三个问题: 1.调用了finishTransaction接口,但是在App重新启动后,[SKPaymentQueue defaultQueue].transactions仍然会有这笔订单。 2.支付完成后,[[NSBundle mainBundle] appStoreReceiptURL]],拿到的票据解析出来里面的商品是空的,需要延迟2秒钟左右在调用[[NSBundle mainBundle] appStoreReceiptURL]]才能获取有效票据。 3.支付完成后,如果用户没有点击最后弹出的确认弹框,等待5秒钟,系统会自己回调 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions; 代理方法。正常应该是用户点击了最后弹出的确认弹框,在回调- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions;方法。 我们在苹果开发者论坛上面找到其他开发者反馈的类似问题,链接如下: https://developer.apple.com/forums/thread/817700 https://developer.apple.com/forums/thread/792437?answerId=849557022#849557022 https://developer.apple.com/forums/thread/817834 https://developer.apple.com/forums/thread/817706 https://developer.apple.com/forums/thread/818586 我们有大量用户升级到了26.4系统,这对于我们造成了巨大的困扰,我们需要你们的帮助,感谢!

CXCallUpdate not working for outgoing calls
I try to update remoteHandle using CXCallUpdate for outgoing call, but this works only on iOS 15 but not on 17 or 18 (16 didn't test). This problem actual only for outgoing calls, but for incoming calls update works fine. func startOutgoingCall(with callID: UUID, userID: String) { let handle = CXHandle(type: .generic, value: userID) let action = CXStartCallAction(call: callID, handle: handle) callController.requestTransaction(with: action) { [weak self] error in // ... } } func updateOutgoingCall(with callID: UUID, groupID: String) { let update = CXCallUpdate() update.remoteHandle = CXHandle(type: .generic, value: groupID) provider.reportCall(with: callID, updated: update) } I also tried phoneNumber type but it seems initial handle that I set to CXStartCallAction not possible to change (value or even type). I use this handle value to implement recall by tap on call in Recents tab of system address book. But since my calls can transform from p2p to group call, I need to update handle value or find some another way to pass call identification info.

"appAccountToken" mismatched in sandbox environment
We're seeing some strange behavior of the appAccountToken when passing it to a purchase in the sandbox environment. Normally we'd expect the same account token to be set on the resulting verfication, but that's not the case. Instead the token seems to be persisted on the API side and reused for some amount of time, meaning there's a mismatch and the connection between account and purchase is lost. This happens consistently even if we send new tokens on each purchase. Has there been any updates to purchase flow in the sandbox environment on Apple's side? .purchase( options: [.appAccountToken(token)] )

HealthKit on macOS
HealthKit is currently not supported on macOS nor tvOS, despite being supported by visionOS. Support for macOS was last asked about[1] here in 2018. My goal is to display interactive data visualisations over workouts collected in HealthKit on macOS. Will this be possible to do in the near future using HealthKit directly? If not, can I somehow read the information from an iPhone and display it on the mac? Cheers, Rodrigo [1] https://developer.apple.com/forums/thread/94937

Different transaction IDs for the same purchase between SKPaymentTransaction and receipt latest_receipt_info
Hello, I am investigating a case where two different transaction IDs appear to refer to the same purchase, and I would like clarification on whether this behavior is expected. Additional context StoreKit version: StoreKit 1 (SKPaymentTransaction) Environment: Production Product type: Auto-renewable subscription Transaction sources The values are obtained from the following APIs: transaction_id from SKPaymentTransaction https://developer.apple.com/documentation/storekit/skpaymentqueue receipt_data from the App Store receipt https://developer.apple.com/documentation/foundation/bundle/appstorereceipturl Observed behavior After an In-App Purchase completes, the app receives: a transaction_id from SKPaymentTransaction the corresponding receipt_data for the purchase When inspecting the receipt, the transaction_id inside latest_receipt_info differs from the transaction_id received directly from the purchase transaction. For clarity: A = transaction_id received from the purchase flow (SKPaymentTransaction) A' = transaction_id found in receipt_data.latest_receipt_info The two values are different, but they differ only by 1. Additional observation The original_transaction_id for A and A' is identical, which suggests that both transaction IDs belong to the same subscription purchase chain. Pattern observation on the ID difference We have observed that the difference between A and A' is consistently exactly 1 (i.e., A' = A + 1) across multiple transactions, not just a single case. This appears to be a reproducible pattern rather than a coincidence. This observation raises an additional question (Question 6 below). API verification When calling: GET /inApps/v1/transactions/{transactionId} Both A and A' return what appears to be the same purchase record. The response data is effectively identical except for the transactionId field. However, when calling: GET /inApps/v2/history/{transactionId} A does not appear in the transaction history only A' appears in the history response Questions If A does not appear in transaction history, where does this transaction ID originate from? Why does Get Transaction Info (/inApps/v1/transactions/{transactionId}) return a valid response for A even though it is not present in the transaction history? Why do A and A' both resolve to what appears to be the same purchase? In this situation, which transaction ID should be treated as the canonical transaction ID for server-side validation? Is this difference related to how StoreKit 1 (SKPaymentTransaction) and the App Store Server API represent transactions? Is the consistent off-by-one difference between the transaction_id from SKPaymentTransaction and the one recorded in latest_receipt_info an intentional behavior of StoreKit 1's internal transaction ID assignment? Specifically, we are wondering whether StoreKit 1 applies some form of internal offset when delivering the transaction ID to the client, while the App Store server records a different (adjacent) ID in the receipt. If so, is this documented anywhere? Note We are currently in the process of migrating to StoreKit 2, but this behavior was observed while investigating our existing StoreKit 1 implementation. Any clarification would help us better understand the correct transaction model during the migration.

How to cancel Auto-renewable subscription bought in TestFlight?
I've read several topics on cancelling subscriptions in sandbox environment, but it seems to me that it could not be applied to TestFlight. I can cancel sandbox subscriptions through Settings > App Store > Sandbox account But since TestFlight does not use sandbox account I cannot cancel a sub from there. Also, TF purchase does not appear in the list of regular subscriptions (Settings > Profile > Media & Purchases). So my question is: is there any way to manually cancel auto-renewable subscription bought in TestFlight build of the app?
