Live Activity without Dynamic Island
Is it possible to display a live activity on the lock-screen without a dynamic island? Or at least without expanding the dynamic island more than just for a small icon? struct SomeWidgetLiveActivity: Widget { var body: some WidgetConfiguration { ActivityConfiguration(for: SomeAttributes.self) { context in } dynamicIsland: { context in DynamicIsland { DynamicIslandExpandedRegion(.leading) { // Seems to be mandatory, any way around it? } } compactLeading: { } compactTrailing: { } minimal: { } } I couldn't quite find a way. Thank you

Critical Alerts Entitlement
Hi Team, We’re following up on our request for the Critical Alert entitlement for our app, which we plan to use to notify users about critical states of their devices. It’s been almost 4 weeks since we submitted the request, and we wanted to check on the typical review timeline so we can plan our upcoming work accordingly. If there’s anything we can provide or clarify to help complete the review or make the process easier, we’d be happy to assist. or the right forum to reach out to.

Batch push issues for commercial apps
The backend service uses the same copy to push to many users in batches. This year, the following problem began to occur. Using http2 send is normal, but when getting the result through the stream id, it always times out. Restarting the service still times out. I hope Apple development engineers can help me find out what the problem is.

Action Required: Apple Push Notification Service Server Certificate Update
Hi Apple Team, we reiceved the following message. Hello, We’re reaching out with a final reminder that the Certification Authority (CA) for Apple Push Notification service (APNs) is changing. APNs updated the server certificates in sandbox on January 21, 2025. APNs production server certificates will be updated on February 24, 2025. To continue using APNs without interruption, you’ll need to update your application’s Trust Store to include the new server certificate: SHA-2 Root: USERTrust RSA Certification Authority certificate. Our web service sends token-based push notifications directly to the Apple Push server. For testing: https://api.development.push.apple.com:443 In production: https://api.push.apple.com:443 We have never installed any certificates for using APNs. Do we need to take any action regarding this message, or can we ignore it?

All Apple Push Notification Architecture
I've built an iOS & Watch OS app using Sign in with Apple & CloudKit exclusively. I'm now wanting to implement Push Notifications. I understand that I need a server to trigger the push notifications (I guess I could spool up a Node server somewhere or use Firebase), but I'd really like to not use any non-Apple backend services. Am I correct in understanding that I can do this with Push Notifications Console, or do I still need a separate backend?

AlarmKit alarms do not fire when foregrounded app is in landscape
Hello! When setting an alarm in an AlarmKit app, the alarm will not fire properly/reliably (the alert presentation is not shown) while the device has an app foregrounded in the landscape orientation. This behaviour has been present since the betas, however until the first party Reminders app showed the behaviour in the iOS 26.2 beta I suspected the issue was in my own code. The behaviour is exhibited when scheduling alarms in several AlarmKit apps: The Reminders app The AlarmKit WWDC Demo Project My own AlarmKit app However alarms scheduled by the stock Clock app do not seem to exhibit the behaviour. Minimal repro with first party app: Be using iOS 26.2 beta Open Reminders app Create an urgent reminder for a time in the not too distant future Open Mail.app Change to landscape orientation Wait for the fire time Observe the phone vibrates at the correct time but no alarm is fired Drag the notifications pane down, observe the LiveActivity has been started Change to portrait orientation Observe alarm fires I have noticed this behaviour from the AlarmKit apps mentioned while foregrounding other apps besides Mail, both first and third party: Photos YouTube Netflix The behaviour does not seem to occur when the foregrounded app is restricted to portrait mode, no matter the actual orientation of the device. In the case of my own app I have tried a multitude of ideas to get it to work reliably, getting alarms to fire in landscape is very intermittent at best and most often works after a fresh reboot. I've submitted a Feedback for the Reminders app: FB20956492. Any advice or suggestions would be appreciated!

Unable to install an app extension when running it for debugging
I've got an app with several app extensions (call extension, action extension, notification service extension, message filtering extension, notification content extension). If I need to interactively debug these then I can select the scheme and run the extension within Xcode for all of them except for the notification content extension, with that I get an error dialog summary saying: Failed to install the app on the device / The provided item to be installed is not of a type that CoreDevice recognizes. Which when expanded has the blumpf posted below. Why can I not run the notification content extension, when I can run any other type of app extension? Failed to install the app on the device.

Error when running Live Activities
Hi there, This is my first time posting here. I'm working on small projects on Swift and SwiftUI now and then. I'm currently trying to develop an application that gets some bus arrival data using API and displaying them with live activities. The thing is that I'm not quite sure how frequently updates work yet. Still trying to figure out if I can update the live activity everytime the data coming right from the API changes or use push notification updates each minute passing by, but that is another thread that I'm going to focus with more details. Everytime i'm trying to deploy my app on my iphone or a simulator this error keeps popping up and I can't figure out why. Any ideas? Let me know if you need any snippet of my code. SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'com.gregorikouk.MapKitTut.BusWidgetKit' error: Error Domain=FBSOpenApplicationServiceErrorDomain Code=1 "The request to open "com.apple.springboard" failed."

Is the Time Sensitive Notification entitlement needed for visionOS?
I noticed the time sensitive entitlement says it's only for iOS and macOS. But without the entitlement, the time sensitive toggle doesn't show in my app's notification settings on visionOS. When I archive my visionOS app for App Store Connect, the entitlement seems to be taken out as it doesn't show in my entitlement list for the build in App Store Connect. I'm confused at this point if the entitlement is really necessary, since it seems to be needed to debug on the simulator at least. I don't have a physical device to test it on unfortunately.

Persist and deliver scheduled local notifications after app update
I have an app available for download in the Apple App Store. The app sends local notifications, which are scheduled at the user's request once the app launches. I've recently learned that when new versions of my app are deployed and automatically update on the user's device, previously scheduled local notifications are deleted. Given my app design, the user can re-launch the app in order to re-schedule the local notifications. This is a bit of a problem, though, because part of my app's value is in reminding the user - so after requesting a local notification, the user expects to receive a local notification and then launch the app, not the other way around. Given this, I've been exploring solutions so my app continues to function as expected (including delivering local notifications, even if the app hasn't yet been launched) after an app update. I've explored .backgroundTasks(), but they too are apparently deleted with an app update and require the app to be re-launched first to work as expected. Another solution might be to use push notifications instead of local notifications, but that seems like a very involved solution if I'm just looking to make sure that local notifications persist after an app update. I can't be the only person to have this dilemma - am I overlooking a simple solution?

Location Push Extension Cannot Wake after 10 mins
Hi team, I'm developing a feature that's collecting the device locations for home security app. We've been following https://developer.apple.com/documentation/corelocation/creating-a-location-push-service-extension apns-push-type set to location. apns-priority set to 5. during testing, we found that the device's notification extension cannot be triggered after device going into lock screen for 10 mins. Wonder should we set the priority to 10? Thanks!

Getting VoIP notifications to work and use iOS call UI when phone is locked/app is in background/Not running
Hey there my application allows users to have video calls with each other using Agora. I have successfully set up incoming call functionality on Android but on iOS I am struggling to get the call ui to appear when the app is not running/in background/locked. To my knowledge this is because there is much stricter security on iOS which is limiting me from calling this. When i initially set it up it worked at first when the app was in the background but I think I was failing to report the call to call kit in time and now it's not working. I'm not sure if I need access to this entitlement: com.apple.developer.pushkit.unrestricted-voip Which i believe is only for the big boys or if I make sure I'm reporting the call to call kit fast enough that I won't encounter this issue and it will consistently work in the background.

Audio Session in Notification Service Extension
Is there anyway that I could use AVAudioSession, AVAudioPlayer or anything similar in Notification Service Extension? I am trying to implement Audio Playback in the Notification Service Extension to play specific audio file when receiving Notification regardless the app state(foreground, background or killed), but I am not able to activate audio session in Notification Service Extension. NSError *sessionError = nil; BOOL success = [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&sessionError]; success = [[AVAudioSession sharedInstance] setActive:YES error:&sessionError]; if (!success) { NSLog(@"Error activating audio session: %@", sessionError); } Below is the error that I got when I am trying to run the code above in Notification Service Extension. Error Domain=NSOSStatusErrorDomain Code=561015905 "Session activation failed" UserInfo={NSLocalizedDescription=Session activation failed}

Push Notifications largely not get transmitted
I have three apps with a very low user rate, so it's easier to compare. In all three apps, when I send a notification to APNs, over two-thirds receive a "Stored - Device Offline" status, but only one or two notifications are delivered afterward. No message has been sent after that. The total number of recipients is 89; 26 were delivered to the device, and 62 were stored in APNs. One was delivered from storage, and one was discarded. All app users are located in the same region, and mobile internet or Wi-Fi is available everywhere. I can't believe that so many iPhone users aren't getting connected to APNs to receive the stored message. Or are event not connected. Or are there any other reasons why a notification cant be transmitted. (User beahaviour, time of not using the app or something else?)

Push Notification Delivery Delays and Failures on iOS Devices
I am experiencing an issue with push notifications on my iOS application. The issue is as follows: On Android devices, push notifications are received immediately without any problems. On iOS devices, the behavior is inconsistent: When the app is in the foreground, notifications are received immediately. When the app is in the background or in recent apps with a significant delay of 5–10 hours, push notifications are not received at all. This behavior creates a major challenge for us, as timely notifications are critical for our app’s functionality. We have already verified the following points on our side: Push notification certificates and APNs setup are correct. Payload and server configurations are valid, as notifications are working fine on Android. No restrictions from the server-side, since Android users receive notifications instantly. It seems the issue is specifically related to iOS devices or APNs delivery. Could you please help us identify the cause and provide guidance on how to resolve this?
