We added a button in the real-time activity that responds within the app upon clicking. Now we're encountering an issue where, if you immediately click this button after swiping down to enter the notification center, it only opens the app without any scheme response. You have to wait for about 1 second after swiping down before the button can respond normally. Could you please tell us why this is happening?

I'm not quite sure whether this post belongs in a Design forum or here, but with iOS 18 Developer Beta 1 and watchOS 11 Developer Beta 1, when a Live Activity is displayed on an Apple Watch, the system font used is SF Pro rather than SF Compact. I would expect that the design guidance would be to stick with SF Compact while on watchOS, and I would expect that the system font, when displayed on the Apple Watch using .supplementalActivityFamilies([.small]), would appear as SF Compact. To ensure that SF Compact appears on my Live Activity when viewed on Apple Watch, I can set a custom font for use with the small supplemental family, but this seems really clunky; is there any other guidance here?

I'm excited to bring my Live Activity to Apple Watch via the .supplementalActivityFamilies([.small]) modifier. However, I'm also wondering whether it is possible for my watchOS app, separately, to initiate a Live Activity and receive updates for it via push notification. From my testing it seems like no, but the function call itself can be made, since ActivityKit is available on watchOS. Are there any other recommendations for how to go about initiating a Live Activity from a watchOS app? Would I have to communicate with a companion iOS app to start the Live Activity on the phone instead?

I looked at all the apis that don't support animation, how does Top Widgets do it? Please ask Apple engineers to help, thank you

So I updated my phone to ios18 beta and ever since then my phone will always crash when I enter screen time but any other application nothing will happen, my phone has gotten so much slower and heats up faster. Lags so much! I dont know what else to do. I have 107gb and my max is 128gb so I don’t see that as the issue. Especially since I can’t enter into my screen time. I waited it out for almost two or one week. it hasn’t changed. restarted my phone and everything. please help asap!!!

When I start a workout in my app, the system shows a Live Activity in the Smart Stack like in the picture. My app opens if I tap on it, but the pause and resume buttons doesn't do anything. I have implemented the PauseWorkoutIntent and ResumeWorkoutIntent which works with the Action Button. I guessed that these would be used from this Live Activity as well, but it seems like not. Has anyone successfully integrated with this? I haven't seen it documented anywhere, although I think it was already included in watchOS 10. This is also shown when using the built in workout app and for that the buttons work as expected.

I have started to work on adding Live Activities to my app in watchOS 11. The app already has interactive Live Activities on the phone that works as expected. I have added a view for the activityFamily: small and it shows up as expected. My problem is that buttons doesn't work. I use the Intent based button, and on the iPhone Lock Screen they work. On the watch, nothing happens. Has anyone got this working? Not sure if I'm missing something or if it's a bug.

Hello there, I'm playing around with the new ControlWidget controls and I'd like to start a Live Activity from on of them like they did in the WWDC Session. Is this only possible using push notifications or is there another way around to do so locally? Thank you.

Hello there, I'm playing around with the new ControlWidget controls and I'd like to know the best approach to launch a Live Activity using these. It seems to be possible according to its WWDC session but my main question is: Is it only doable using push notifications? Thank you.

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?

I work on an App that uses Live Activities and shows a countdown. We want to use it without the seconds. We are currently using Text(getDate(), style: .relative). Is there a new method in Swift to show the countdown on a Live Activity without seconds being displayed.

The activityStyle documentation incorrectly lists tvOS - https://developer.apple.com/documentation/activitykit/activitystyle Spoke to someone at WWDC who asked I report this here. Thanks!

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?

I have a live activity and I can't get the colors to work correctly when the iPhone has the focus mode set to do not disturb. My activity uses the system background and foreground. The live activity goes completely black. I have tried setting activityBackgroundTint and activitySystemActionForegroundColor to nil but that still gives a black activity that looks like this.

Notifying the Live Activity When Countdown is Complete: Once the countdown timer reaches zero, how do I notify the live activity? What is the best approach to ensure the live activity updates accurately and promptly? Handling App Suspension in the Background: When my app is in the background, it gets suspended. Should I set up a job queue on the backend to send an update push notification when the timer ends? Is there a more efficient way to handle this? Ensuring Timer Accuracy: Since this feature deals with time, I am concerned about the accuracy of the timer. How can I ensure the countdown timer remains accurate even when the app is not in the foreground? Any answers, insights, or guidance on these issues would be greatly appreciated. Thank you in advance for your help!

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 ?

I have a question regarding the Live Activities feature introduced in iOS 16.1. According to the documentation, Live Activities can be updated via push notifications. However, I am curious to know if Live Activities can still receive updates via push notifications when push notification permissions are turned off for an app. Could you please clarify whether Live Activities updates are independent of the push notification permissions setting, and if so, how the update mechanism works in this scenario? Thank you for your assistance. Best regards,

Our app is a time reporting service with various functions around that. The user checks in at work, checks out when they go home. We thought it'd be useful to provide a live activity to show how long they have worked for. There is also a couple of other cool things we could do that users would love, but i couldn't find definitive answers to the questions below. 1. We have a geofence-based function that checks the user in when they for example arrive at work, and check them out when they go home, so that they don't have to open the app. However, this means that we will need to start and end the live activity from within a geofence trigger. Is this possible? 2. It seems that the maximum time for a live activity is 8 hours? Sometimes people work for longer... How would we solve this? i would be fine with 12 since it would solve most cases. Is it possible somehow to go beyond 8 hours up to 12? If not, is there a callback that "8 hours are up!" so that i could do a final update on the live activity from a counter to "you started working at 09:04" 3. I have seen that some live activities have buttons. It would be neat if the user can check out via a button on the live activity. However, since we take location and call our servers when checking out, we need to be able to use both the locationmanager and make a network call from the live activity. Is this possible? Thanks in advance, Cheers

I'm building a live activity with push token updates for my app as described in the documentation and implemented in the EmojiRangers example. The workflow is working fine for fairly new devices (iPhone > 13) - however, the asynchronous pushTokenUpdates sequence used to observe changes to the push token of a Live Activity is not getting triggered on some older devices (i.e. iPhone XR, iPad 8th Generation). Is there a minimum device version for this sequence? This is the code I'm using: "--------Task--------" gets printed, "--------PushTokenUpdate--------" does not (on older devices): do { let activity = try Activity.request( attributes: matchAttributes, content: .init(state: initialContentState, staleDate: nil), pushType: .token ) Task { print("--------Task--------") for await pushToken in activity.pushTokenUpdates { print("--------PushTokenUpdate--------") } } } catch { Logger().error("Error starting LiveActivity: \(String(describing: error))") }

i'm struct dynamic island detail content dynamicIsland: { context in DynamicIsland { expandedContent(context: context) } compactLeading: { .... } compactTrailing: { ... } i want show different content based on context. private func expandedContent(context: ActivityViewContext<xxxx>)->DynamicIslandExpandedContent<some View> { if (context.state.style == 0) { return expandedControlContent1(context: context) } else if (context.state.style == 1) { return expandedControlContent2(context: context) } else { return expandedControlContent3(context: context) } } compiles error Function declares an opaque return type 'some View', but the return statements in its body do not have matching underlying types
