How to stop today's instance of repeating alarms in AlarmKit without affecting future days?
I'm using the new AlarmKit framework to build a Swift app that lets users schedule multiple repeating alarms. The goal is to allow users to stop all alarms for today if they wake up early, but the alarms should still ring on their scheduled days in the future (for example, every Monday). What I tried: When the user chooses to stop alarms for today, I delete all alarms and re-add them. However, this doesn't work as expected. If today is Monday and I delete and re-add the alarm with .weekday = .monday, it still rings today. That means re-adding the alarm doesn't skip today's instance, even though it's repeating. What I want to achieve: Skip or suppress today's alarms when the user stops them manually Keep the same alarms active for their scheduled days in the future Questions: Is there a way in AlarmKit to prevent a repeating alarm from ringing today if it was just re-added or there are better alternatives to this problem? Is the only workaround to delay re-adding until after today’s alarms would have fired? What is the best approach to achieve this?

Token Selection from DeviceActivityReport
I'd like to allow users to select apps to shield from a DeviceActivityReport (similar to how Apple's Screen Time Settings activity report allows a user to "add limits" to a selected app in the report. What I need to do is pass an appToken from the DeviceActivityReportExtension to my app. I realize the extension is sandboxed and doesn't allow "private" data to be seen outside of the sandbox. The docs state: To protect the user’s privacy, your extension runs in a sandbox. This sandbox prevents your extension from making network requests or moving sensitive content outside the extension’s address space. However, tokens aren't "sensitive". I want to pass a token set out of the sandboxed extension so users can select certain apps from the report that my app can use for setting limits, etc. I thought using App Groups and saving data with UserDefaults with a suiteName for my app group would do it, but it doesn't appear to allow me to pass the token data. Yes I'm using the same KEY for both as I set a config enum to ensure it's the same and I can pass tokens successfully between other extensions/apps in the app group, but not the report extension. It seems the app and the extension have their own stores as the report extension can write to and read from a store but despite being the same suiteName, other apps in the app group don't get or send data to the Report Extension. I realize this is probably due to the design with the sandbox to protect user privacy, however it seems an exception should be made for passing tokens (or even better allow passing through another method like a callback, etc). Is there ay way to accomplish passing a token from the sandboxed report extension to my app?

Applinks failing
Hello, We're facing an issue with app links failing and falling back to browser website journeys. Our apple-app-site-association file is hosted publicly and the app to app journeys have been working correctly up to very recently - we are trying to identify any potential network infra changes that could have impacted the Apple CDN being able to retrieve the apple-app-site-association file. We can see in the iPhone OS logs that the links cannot be verified by the swcd process, and using the app-site-association.cdn-apple.com/a/v1 api via curl can also see the CDN has no record of the AASA file. Due to the traffic being SSL and to a high volume enterprise site it is difficult for use to trace activity through anything other that the source IPs - we cannot filter on user-agent for "AASA-Bot/1.0.0" as breaking the SSL would be impactful due to the load. Is it possible to get a network range used by the Apple CDN to retrieve the AASA file as this would help us identify potential blocking behaviour? Thank you.

Does Live Caller ID Lookup entirely replace Call SIP content, or are they ever combined?
If an iPhone receives an incoming call with some partial sip content (for example it contains a name but not an image, or vice versa) and if there is an app enabled for Live Caller ID Lookup, and the result of that lookup supplies data not in the sip (i.e. the lookup returns an image, but not a name, or vice versa). Then could the OS combine data from both sources, or is whatever is returned from the LCIDL what gets displayed in the call screen. I suppose that is the case but just want to enquire to make sure. Thank you

Siri mispronouncing app name
The name of our app is a portmanteau, and Siri is getting it slightly wrong. It’s putting the emphasis on the second and fourth syllables instead of the first and third. Kind of like if someone starting singing /tinˈeɪʒd muˌtent/. It’s just wrong enough to be funny. It still recognizes the correct name when someone says “hey Siri”. We’ve already tried adding CFBundleSpokenName and INAlternativeAppNamePronunciationHint to info.plist, but neither is changing how Siri says it. We can’t put it in AppIntentVocabulary.plist because we don’t know the key path for the app name.

Core Spotlight searching only for title
I just adding a way to donate my app's data to Core Spotlight using CSSearchableIndex, but I'm finding that spotlight is only searching for the title of the CSSearchableItem I create. I know the index is working, because it always finds the item through the title property, but nothing else. This is how I'm creating the CSSearchableItem: - (CSSearchableItem *) createSearchableItem { CSSearchableItemAttributeSet* attributeSet = [[CSSearchableItemAttributeSet alloc] initWithContentType: UTTypeText]; attributeSet.title = [self titleForIndex]; attributeSet.displayName = [self titleForIndex]; attributeSet.contentDescription = [self contentDescriptionForIndex]; attributeSet.thumbnailData = [self thumbnailDataForIndex]; attributeSet.textContent = [self contentDescriptionForIndex]; CSSearchableItem *item = [[CSSearchableItem alloc] initWithUniqueIdentifier: [self referenceURLString] domainIdentifier:@"com.cjournal.cjournal-Logs" attributeSet:attributeSet]; item.expirationDate = [NSDate distantFuture]; return item; } There's a lot of confusing tips around which say specifying the 'textContent' should work, and/or setting the displayName is essential, but none of these are working. Is there something I'm missing with my setup? Thanks.

Strange behavior of Speakerbox (or CallKit) with headset operation
I've run Speakerbox(https://docs-assets.developer.apple.com/published/8e99045a90e2/MakingAndReceivingVoIPCallsWithCallKit.zip) to check the behavior of CallKit. When there was one active call and one on hold and another call was received, the behavior was defferent depending on whether I operated it from a headset or not. No headset or operated from CallKit screen When "End & Accept" tapped: the active call is hung up, and the received call is answered. When "End Held & Accept" tapped: the held call is hung up, the active call is held, and the received call is answered. Operated from headset Answer opeation cannot be performed for unknown reasons Disconnect operation caused that all calls other than the one on hold are hung up and the held call is unheld. Hold operation caused that the active call is held and the received call is answered. (Strangely, there are two held calls.) And when I toggle calls at this time, one of the two on hold is hung up for unknown reasons. I tried changing the settings of CXProviderConfiguration and CXCallUpdate, and changing the options in the Audio Session category, but it did not improve. I checked CXActions occurring, and it was as follows. (Call A = held call, Call B = active call, Call C = received call) Disconnect (or Answer?) operation (lacking CXEndCallAction for Call A) CXEndCallAction for Call B CXAnswerCallAction for Call C CXEndCallAction for Call C <- weird CXSetHeldCallAction for Call A onHold=false Hold operation (lacking lacking CXEndCallAction for Call A) CXSetHeldCallAction for Call B CXAnswerCallAction for Call C Toggle calls CXSetHeldCallAction for Call C onHold=true CXSetHeldCallAction for Call A onHold=false CXSetHeldCallAction for Call B onHold=false <- weird CXEndCallAction for Call B

Default dialer abilities & limitations
I've been trying to understand what kind of UX is available if my app is using the default-dialer capability. I have found https://developer.apple.com/documentation/livecommunicationkit/preparing-your-app-to-be-the-default-dialer-app and I am in the EU. On android I built the UX I want and it's quite neat, so now I'm trying to work. out what I can get on iOS. Because the product is kind of worthless with just android. I have built a simple dialer ux with a numberpad, contact lookup etc. Then when the user presses the Call button does it have to pop up the system prompt "Call number"? Does it have to swap over to the system ui for the actual call? So there's no way to show information about the call, during the call? Or am I using the frameworks incorrectly? I am very new to iOS development. TrueCaller and others show validation, but as I understand it they pre-fetch all the data, I can't do that.

How to get a phone into a state where it's possible to test text filtering?
I'm currently finding it impossible to get a text filtering extension to be invoked when there's an incoming text message. There isn't a problem with the app/extension because this is the same app and code that is already developed, tested, and unchanged since I last observed it working. I know if there's any history of the incoming number being "known" then the extension won't get invoked, and I used to find this no hindrance to testing previously provided that: the incoming number isn't in contacts there's no outgoing messages to that number there's no outgoing phone calls to the number. This always used to work in the past, but not anymore. However, I've ensured the incoming text's number isn't in contacts, in fact I've deleted all the contacts. I've deleted the entire phone history, incoming and outgoing, and I've also searched in messages and made sure there's no interactions with that number. There's logging in the extension so I can see its being invoked when turned on from the settings app, but its not getting invoked when there's a message. The one difference between now and when I used to have no problem with this - the phone now has iOS 18.5 on it. Its as if in iOS 18.5 there ever was any past association with a text number, its not impossible to remove that association. Has there been some known change in 18.5 that would affect this call filtering behavior and not being able to rid of the incoming message caller as being "known" to the phone? Update I completely reset the phone and then I was able to see the the message filter extension being invoked. That's not an ideal situation though. What else needs to be done beyond what I mentioned above in order to get a phone to forget about a message's number and thus get an message filtering extension to be invoked when there's a message from that number?

Can not replicate the Apple Review error
Hello there! So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash. So I know the "it works on my computer" sounds bad but....works on my computer and my test system. Dont know what to do since I dont know how to replicate the error. This is the rely they sent me: Issue Description The app exhibited one or more bugs that would negatively impact users. Bug description: at time of review the app’s interface went blank at launch. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.4.1 Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.

Request: Higher-Frequency IMU Access on Apple Watch for Sports Performance Apps
Hi everyone, I’m building a sports performance app for Apple Watch that uses the onboard IMU to analyze swings and impacts in sports like tennis and golf. The goal is to estimate club/racket head speed, ball speed, and shot quality in real time from wrist motion data. With Core Motion, I can currently get deviceMotion updates at ~100 Hz. While this is fine for general movement tracking, the actual ball impact happens much faster — 5–10 ms in tennis and ~0.5 ms in golf. Many of the high-frequency vibration/impact components are missed at 100 Hz, making it hard to directly measure or more accurately estimate certain performance metrics. Questions for Apple / community: 1. Is there a way to access raw accelerometer and gyroscope data at higher sampling rates (e.g., 500–1000 Hz) on Apple Watch? 2. If not, is this due to hardware limitations or an API/software constraint? 3. Are there any research, partner, or beta programs that allow deeper sensor access for sports-science use cases? Even modest increases in IMU sampling could unlock more accurate ball-speed estimates, impact force analysis, and strike-quality detection without needing external sensors — making Apple Watch a best-in-class wearable for precision sports analytics. Happy to share more about the current approach, sample data, and potential use cases if helpful. Thanks, Max

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Live Caller ID Lookup Implementation
Hello I'm working on Live Caller ID Lookup implementation on my own pet-project, as I understood I need to create app and extension for this app. I also created test PIR-service. I did configure serviceURL, tokenIssuerURL and userTierToken. In My app I implemented following code Task { if LiveCallerIDLookupManager.shared.status(forExtensionWithIdentifier: "some-extension") == .disabled { `//` Show an alert. print("LiveCallerIDLookupManager is disabled") } do { // Open Settings. try await LiveCallerIDLookupManager.shared.openSettings() } catch { } It does open Call settings, but I don't understand what should I do next.

How to display a full-screen light based (sunrise) alarm notification at specific time (like Clock app)? Can Critical Alerts help with visuals too?
I'm building a light-based(sunrise) alarm iOS app using SwiftUI , the idea is to wake users not with sound, but with a full-screen bright light UI (mimicking sunrise or a light alarm clock). I'd like to replicate behavior similar to the native Clock app: My goal: When the scheduled time is reached, forcefully display a full-screen "light" screen, even if the device is: locked running another app or the app is backgrounded The problem: So far, I can: Show a full-screen AlarmView only if the app is opening But I cannot: Automatically wake the screen when app is closed My confusion: I've read that Critical Alerts allow bypassing Do Not Disturb and Silent Mode but that's only for sound right? Can Critical Alerts also help with waking the screen or displaying visuals like full-screen UI automatically? If not, is there any way to simulate this kind of alarm: light-based screen effect ( sunrise alarm clock) triggered automatically at a specific time without needing the user to manually tap the notification? Do I need to consider: PushKit + VoIP? CallKit (but it's meant for calls)? Background tasks + silent push? Or is it simply impossible without special entitlements? Thanks in advance for any insights. This seems like a simple use case (light-based alarm), but I’m surprised how limited the options is.

Bug in Screen Time API: familyActivityPicker dismisses a presenting sheet on iOS 18.4 and above
Hello, I’m presenting the familyActivityPicker from a presented sheet in my application. When I select some apps, categories or websites and tap “Done”, the familyActivityPicker is dismissed but the presenting sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. If I tap on “Cancel” from the familyActivityPicker, the sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. The same code works perfectly fine on iOS 18.0, iOS 18.1, iOS 18.2 and iOS 18.3. Is this a known-issue? If opened the feedback FB18369821 for this. Regards, Axel

iOS 26 Empty Stack Crash
When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes. However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues. Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes. app-2025-09-19-161044.ips.txt

AlarmKit can we automatically acknowledge the alarm or set a time period the alarm should alert for
My use case is a Repeat Timer app. The user can configure a repeating timer, say: 8 minutes with 3 sets So I would like to configure either 3 alarms (8mins, 16mins, 24mins) or a repeating alarm (8mins every 3 mins) BUT... I would like the first and second alarms to break through but only for 5 seconds for example, and then stop (so the user doesn't need to tap the screen to silence the alarm). I don't think this is possible after reading the API docs, but am asking the question anyway. Thanks for any advice or guidance here, and happy WWDC!

I have built a simple dialer ux with a numberpad, contact lookup etc. Then when the user presses the Call button does it have to pop up the system prompt "Call number"? Does it have to swap over to the system ui for the actual call? So there's no way to show information about the call, during the call? Or am I using the frameworks incorrectly? I am very new to iOS development. TrueCaller and others show validation, but as I understand it they pre-fetch all the data, I can't do that.

How to get a phone into a state where it's possible to test text filtering?
I'm currently finding it impossible to get a text filtering extension to be invoked when there's an incoming text message. There isn't a problem with the app/extension because this is the same app and code that is already developed, tested, and unchanged since I last observed it working. I know if there's any history of the incoming number being "known" then the extension won't get invoked, and I used to find this no hindrance to testing previously provided that: the incoming number isn't in contacts there's no outgoing messages to that number there's no outgoing phone calls to the number. This always used to work in the past, but not anymore. However, I've ensured the incoming text's number isn't in contacts, in fact I've deleted all the contacts. I've deleted the entire phone history, incoming and outgoing, and I've also searched in messages and made sure there's no interactions with that number. There's logging in the extension so I can see its being invoked when turned on from the settings app, but its not getting invoked when there's a message. The one difference between now and when I used to have no problem with this - the phone now has iOS 18.5 on it. Its as if in iOS 18.5 there ever was any past association with a text number, its not impossible to remove that association. Has there been some known change in 18.5 that would affect this call filtering behavior and not being able to rid of the incoming message caller as being "known" to the phone? Update I completely reset the phone and then I was able to see the the message filter extension being invoked. That's not an ideal situation though. What else needs to be done beyond what I mentioned above in order to get a phone to forget about a message's number and thus get an message filtering extension to be invoked when there's a message from that number?

Can not replicate the Apple Review error
Hello there! So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash. So I know the "it works on my computer" sounds bad but....works on my computer and my test system. Dont know what to do since I dont know how to replicate the error. This is the rely they sent me: Issue Description The app exhibited one or more bugs that would negatively impact users. Bug description: at time of review the app’s interface went blank at launch. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.4.1 Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.

Request: Higher-Frequency IMU Access on Apple Watch for Sports Performance Apps
Hi everyone, I’m building a sports performance app for Apple Watch that uses the onboard IMU to analyze swings and impacts in sports like tennis and golf. The goal is to estimate club/racket head speed, ball speed, and shot quality in real time from wrist motion data. With Core Motion, I can currently get deviceMotion updates at ~100 Hz. While this is fine for general movement tracking, the actual ball impact happens much faster — 5–10 ms in tennis and ~0.5 ms in golf. Many of the high-frequency vibration/impact components are missed at 100 Hz, making it hard to directly measure or more accurately estimate certain performance metrics. Questions for Apple / community: 1. Is there a way to access raw accelerometer and gyroscope data at higher sampling rates (e.g., 500–1000 Hz) on Apple Watch? 2. If not, is this due to hardware limitations or an API/software constraint? 3. Are there any research, partner, or beta programs that allow deeper sensor access for sports-science use cases? Even modest increases in IMU sampling could unlock more accurate ball-speed estimates, impact force analysis, and strike-quality detection without needing external sensors — making Apple Watch a best-in-class wearable for precision sports analytics. Happy to share more about the current approach, sample data, and potential use cases if helpful. Thanks, Max

For receiving audio in PushtoTalk, channelManager(_:didActivate:) not called when app receives first push after backgrounding
I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Live Caller ID Lookup Implementation
Hello I'm working on Live Caller ID Lookup implementation on my own pet-project, as I understood I need to create app and extension for this app. I also created test PIR-service. I did configure serviceURL, tokenIssuerURL and userTierToken. In My app I implemented following code Task { if LiveCallerIDLookupManager.shared.status(forExtensionWithIdentifier: "some-extension") == .disabled { `//` Show an alert. print("LiveCallerIDLookupManager is disabled") } do { // Open Settings. try await LiveCallerIDLookupManager.shared.openSettings() } catch { } It does open Call settings, but I don't understand what should I do next.

How to display a full-screen light based (sunrise) alarm notification at specific time (like Clock app)? Can Critical Alerts help with visuals too?
I'm building a light-based(sunrise) alarm iOS app using SwiftUI , the idea is to wake users not with sound, but with a full-screen bright light UI (mimicking sunrise or a light alarm clock). I'd like to replicate behavior similar to the native Clock app: My goal: When the scheduled time is reached, forcefully display a full-screen "light" screen, even if the device is: locked running another app or the app is backgrounded The problem: So far, I can: Show a full-screen AlarmView only if the app is opening But I cannot: Automatically wake the screen when app is closed My confusion: I've read that Critical Alerts allow bypassing Do Not Disturb and Silent Mode but that's only for sound right? Can Critical Alerts also help with waking the screen or displaying visuals like full-screen UI automatically? If not, is there any way to simulate this kind of alarm: light-based screen effect ( sunrise alarm clock) triggered automatically at a specific time without needing the user to manually tap the notification? Do I need to consider: PushKit + VoIP? CallKit (but it's meant for calls)? Background tasks + silent push? Or is it simply impossible without special entitlements? Thanks in advance for any insights. This seems like a simple use case (light-based alarm), but I’m surprised how limited the options is.

Bug in Screen Time API: familyActivityPicker dismisses a presenting sheet on iOS 18.4 and above
Hello, I’m presenting the familyActivityPicker from a presented sheet in my application. When I select some apps, categories or websites and tap “Done”, the familyActivityPicker is dismissed but the presenting sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. If I tap on “Cancel” from the familyActivityPicker, the sheet is also dismissed on iOS 18.4, iOS 18.5, iOS 26 beta 1 and 2. The same code works perfectly fine on iOS 18.0, iOS 18.1, iOS 18.2 and iOS 18.3. Is this a known-issue? If opened the feedback FB18369821 for this. Regards, Axel

iOS 26 Empty Stack Crash
When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes. However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues. Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes. app-2025-09-19-161044.ips.txt

AlarmKit can we automatically acknowledge the alarm or set a time period the alarm should alert for
My use case is a Repeat Timer app. The user can configure a repeating timer, say: 8 minutes with 3 sets So I would like to configure either 3 alarms (8mins, 16mins, 24mins) or a repeating alarm (8mins every 3 mins) BUT... I would like the first and second alarms to break through but only for 5 seconds for example, and then stop (so the user doesn't need to tap the screen to silence the alarm). I don't think this is possible after reading the API docs, but am asking the question anyway. Thanks for any advice or guidance here, and happy WWDC!
