Somewhat rarely, but often enough to be a problem, our live activities will entirely lock up with a frozen progress spinner and a dimmed appearance. We cannot figure out what this spinner means nor how to avoid it as it is not documented anywhere. No logs appear in Xcode nor in Console.app. We have more frequent updates enabled and are sending an update maybe once every 2 minutes, nothing that should cause us to exceed our quota. We cannot reproduce in a debugger Can we get some guidance on how to avoid this?

Hello. I am working with the iOS 18b8 and Xcode 16b6 betas, updating a Live Activity Widget to adopt the new FormatStyle variants of the SwiftUI Text views. We used to use: Text(workoutStartDate, style: .relative) and it seems with iOS 18 we can replace it with: Text(workoutStartDate, format: .relative(presentation: .numeric, unitsStyle: .wide)) The former code would auto-increment, allowing a user to look at their Live Activity and see the duration of their workout so far ticking by. The new code does provide a nice relative duration string, but it doesn't auto-increment in the Live Activity's View – I need that functionality. I also updated other Texts in the Live Activity's View to adopt the .timer and .stopwatch FormatStyles. Those auto-increment and update no problem – once I realized I needed to provide a TimeDataSource<Date>.currentDate and not a simple Date. But in this .relative case, there is no auto-incrementing, and I'm guessing it may be due to providing a Date (workoutStartDate) and not a TimeDataSource<Date> as TimeDataSource seems to be the magic to make the Text auto-increment (or it's possible this format simply doesn't support auto-increment? bummer if so since the prior way did). How can I have a TimeDataSource<Date> that vends my arbitrary date (workoutStartDate)? I dug around, didn't find anything, but I wouldn't be surprised if I was overlooking something. PS: I have tried other approaches to solve this, such as simply using a .timer or .stopwatch format. That would change the under experience under iOS 18, and we think degrade it (the relative textual representation is nicer and provides distinction from the .timer also in the same View). We could keep the former approach, despite the minor layout issues under iOS 18. I have considered additional approaches as well – and am totally open to more! Here tho, I am truly curious how one might provide a custom TimeDataSource anchored at a date we provide (perhaps dynamically). Thank you.

Hi, We’ve developed a workout app with a Live Activity feature to help users launch the mirroring view on iPhone, similar to the built-in workout app for biking activities. While Live Activities are now available on watchOS 11, the integration feels a bit off for our Workout app. Is there a way to disable or exclude our Live Activity from appearing on watchOS? Currently, when a user starts a workout, the Live Activity appears at the bottom of the screen, requiring users to tap the screen before they can use our app. The built-in Workout app doesn’t have this issue. Additionally, our Live Activity appears in the Smart Stack, duplicating content with the built-in Workout Live Activity. We’re unsure if we missed any keys or settings to exclude Live Activity from watchOS.

Our watchOS App isn't opened when tapping on a Live Activity. Added the following to our Info.plist and still get the Open on iPhone option. <key>WKSupportsLiveActivityLaunchAttributeTypes</key> <array/> Is there something else we need to configure?

Our team has recently added support to our app for Live Activities where the source of the data is driven from the app itself (not push notifications). We've noticed a crash happening in our core data code caused by the following error thrown by the addPersistentStore function where it would attempt to recover and eventually crash. Here's an error we created to help us debug that contains the error details: Domain: CoreData Code: 1 NSLocalizedDescription: Error performing migration for databaseName=mydb.sqlite. Error details=The file couldn’t be saved because you don’t have permission. - userinfo: ["reason": No permissions to create file; code = 1] After some trouble shooting, we managed to reproduce the issue by doing a hard reboot while we're running a live activity. It appears that when the device starts back up, the Live Activity starts which triggers the app to hit didFinishLaunchingWithOptions which is where we get our Core Data store initialized. The problem is that our app uses Data Protection using NSFileProtectionCompleteUntilFirstUserAuthentication and we'd prefer to keep it that way. The Core Data db is present in the app sandbox and we're also seeing logs to suggest a failure trying to access NSUserDefaults as well. Is there an accepted solution for this? Is it expected that a Live Activity would cause an application to launch prior to the device being unlocked for the first time? Is there a way to change that?

In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called. In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18. Has anyone got this working? Any comments from an Apple engineer on this?

Is there a trick to getting the new Live Activities on Apple Watch working via the simulator? I have an iPhone paired to a watch simulator, but live activities created on the phone aren't appearing on the watch Smart Stack. It looks like maybe the Smart Stack isn't functional on the watch simulator, as there are a bunch of blank tiles where the Smart Stack should be.

The Human Interface Guidelines for Live Activities provide several examples of compact presentations that have a timer counting down formatted like "3min" or "3m", similar to the timers in the Clock app. Such examples can be found in this Stack Overflow question: https://stackoverflow.com/questions/77551496/is-it-possible-to-make-an-only-minutes-1m-countdown-in-a-live-activity A Timer initialized with init(timerInterval:pauseTime:countsDown:showsHours:) has provided a live countdown timer in widgets and live activities, but the formatting is limited. And since live activities come with limitations that prevent us from using Timers, there's no real way to implement this kind of thing ourselves. What is Apple's official guidance for implementing this kind of timer for the compact presentation?

Hi, I'm developing a Live Activity Widget that shows a count down timer. In the current solution I have a stop watch that is responsible for handling the start, stop, resume, reset function. When the stop watch starts I have timer that calls on an updateTime function every 0.2 seconds. This works well. The problems comes when I try to use my stop watch in the Live Activity Widget. I have a timer that updates the live activity attributes with content every 0.5 second. // Start the activity let activity = try? Activity.request(... DispatchQueue.main.async { self.logger.log("Start internal timer") self.timer = Timer.scheduledTimer(withTimeInterval:0.5, repeats: true) { _ in self.logger.log("Update activity widget.") self.updateActivity() } } Is this a correct approach? If not what should I use to implement a stop watch with a count down timer and a corresponding progress bar/view?

Hey there, i implemented live activity in my app and iam trying to start the live activity from push notification, updates works fine even when the app is in background but starting the activity creating issue mostly on background and kill mode when i check the delivery of live activity on cloudkit console it says stored for device power considerations. anyone having the same issue ?

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.

Is there a way to implement controls for background audio using ActivityKit like in the Apple Music application? I didn't found anything in your documentation about handling actions like this except deep links, but they're not suitable for this use case
