Hey there, Create Live activity in my project, after executing the creation method, back to the background, real-time activity UI is not displayed, but click Smart Island is effective, now do not know where the problem appears? Has anyone experienced this problem？ Thanks

Greetings, i have been watched the video and looked for codes to apply live activity for watch. problem is in preview always show my widget as medium size even if apply supporting widget family and changing the content of preview to dynamicIsland .compact however preview still shows me the medium size everytime. what is wrong ?

Hi, I'm a bit stuck when it comes to implementing live activities. I'm trying to start one by sending a push. my activity attributes looks like: import Foundation import ActivityKit public struct NeoPrototypeActivity: ActivityAttributes { public let classId: String public let name: String public let room: String public let startTime: Date public init(classId: String, name: String, room: String, startTime: Date) { self.classId = classId self.name = name self.room = room self.startTime = startTime } public struct ContentState: Codable & Hashable { public let participationState: ParticipationState public init(participationState: ParticipationState) { self.participationState = participationState } } } public enum ParticipationState: String, Codable, Hashable, Equatable { case upcoming case upcomingOnWaitingList case checkedIn case waitingList case lostSpot case lostSpotFromWaitingList case classCompleted public var description: String { switch self { case .upcoming: return "Upcoming" case .upcomingOnWaitingList: return "Upcoming on Waiting List" case .checkedIn: return "Checked In" case .waitingList: return "Waiting List" case .lostSpot: return "Lost Spot" case .lostSpotFromWaitingList: return "Lost Spot from Waiting List" case .classCompleted: return "Class completed" } } } which I have in a SPM package that is imported by my widget and iOS targets. Then I am sending a push notification (to my simulator in this case) with the following payload { "aps": { "timestamp": 1728419211, "event": "start", "content-state": { "participationState": "upcoming" }, "attributes-type": "NeoPrototypeActivity", "attributes": { "classId": "1234", "name": "Indoor Running", "room": "room 2", "startTime": "2024-10-19T13:22:59+02:00" }, "alert": { "title": "Hola Mundo", "body": "Todo Bien" } } } I am using the right values for the deviceID when sending the push. I get a 200 ok from the CloudKit console. yet my live activity doesn't start. I'm trying to look at the errors in the Console app and the only relevant thing is see is: [NeoPrototypeActivity] Error creating activity: NSCocoaErrorDomain (4864) The data couldn’t be read because it isn’t in the correct format. It seems like a decoding error, but I don't know what exactly failed I wrote some test to try the decoding like: import Testing import Foundation @testable import PrototypeActivities @Test func decoding() async throws { struct StateContainer: Codable { let participationState: ParticipationState } let jsonString = """ { "participationState": "upcoming" } """ let json = try #require(jsonString.data(using: .utf8)) let result = try JSONDecoder().decode(StateContainer.self, from: json) #expect(result.participationState == .upcoming) } @Test func decodingActivity() throws { // let jsonString = """ // { // "classId": "1234", // "name": "Indoor Running", // "room": "room 2", // "startTime": "2024-10-19T11:22:59Z" // } // """ let jsonString = """ { "classId": "1234", "name": "Indoor Running", "room": "room 2", "startTime": 1729337784 } """ let json = try #require(jsonString.data(using: .utf8)) let jsonDecoder = JSONDecoder() // jsonDecoder.dateDecodingStrategy = .iso8601 let activity = try jsonDecoder.decode(NeoPrototypeActivity.self, from: json) #expect(activity.classId == "1234") #expect(activity.name == "Indoor Running") }``` but even with using the default JSON decoder date format, I still get the same error. Not sure how to fix this or to get more details.

With iOS 18, Text has a new initializer that takes in a TimeDataSource and a DiscreteFormatStyle. Similar to this question, I'd like to make a compact timer but can't find a way to do that with any of the system formats. Since the new API takes in a DiscreteFormatStyle though I figure I could make my own. This works in an app but not in a Live Activity; in Previews it crashes and in the simulator the view looks like placeholder. Are custom format styles not supported in this case? Or might there something wrong with my implementation? Formatter Preview Crash Log

There seems to be a misalignment when using VoiceOver and selecting the leading/trailing regions in the expanded presentation for Live Activities. This is demonstrated with an extremely basic sample project, where the expanded region is defined by the following code: DynamicIsland { DynamicIslandExpandedRegion(.leading) { Text("Leading") } DynamicIslandExpandedRegion(.trailing) { Text("Trailing") } DynamicIslandExpandedRegion(.bottom) { Text("Bottom \(context.state.emoji)") } } Is this simply a bug or am I doing something incorrectly/is there a workaround?

When I reboot my iPhone 14 pro with Live Activity started, KeyChain information disappears. So there is a problem that I have to sign-in again when I enter the app. There is no problem rebooting the iPhone without Live Activity. iOS17 didn't have this problem.

Hello, we have an app that has a case where the user can turn on a feature that starts a timer for a thing when they arrive at a specific location. Our app also has a live activity to show the timer. Naturally, we're trying to make our live activity to start counting when the geofence triggers, but we get ActivityAuthorizationError.visibility. If an activity is already running, it's possible to turn it off. So, our question is basically if there's any way to make the geofence trigger start our live activity? Thanks

Hi, working on customising my live activity Smart Stack layout for ios18. A thing that is very frustrating is that I consistently looks different for me in the Xcode preview and on the actual watch. See attached screenshots below. The sizes are different, and italic doesn't work on the watch, for example. It makes it time-consuming and unpredictable, so I was wondering if this is a known issue or if I'm doing something wrong, and also can I do anything? thanks edit: this is the layout: var body: some View { VStack(alignment: .center, spacing:4) { HStack(alignment: .center) { IconView(resource: "n-compact-w", bgColor: Color.checkedIn, padding: 2, paddingRight: 6, paddingBottom: 6) .frame(maxWidth: 25, maxHeight: 25).aspectRatio(1, contentMode: .fit) Text("Checked Out") .font(.title3).bold() } Text(status.loc) .font(.headline) .multilineTextAlignment(.center) Text(FormatUtils.getFormattedDateTime(status.time)).font(.subheadline) .multilineTextAlignment(.center).italic() } }

When I request channel list for bundle id "com.apnspush.LiveActivityPushDemo", the request returns "TopicMismatch". Then when I request channel list for bundle id "com.apnspush.liveactivitypush", the request return is normal. I have tried all my bundle ids that include capital letters, they all failed with "TopicMismatch".

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.

I'm using Live Activity features in my app, but I want to customize the user experience across different Apple devices. Specifically, I'd like to: Keep Live Activity enabled and functioning on the iPhone Disable or prevent Live Activity from appearing on the connected Apple Watch Is this level of device-specific control possible with Live Activity? If so, what's the best approach to implement this functionality? What I've tried: I've looked through Apple's documentation on Live Activity, but couldn't find specific information about device-level control. I've experimented with ActivityKit, but haven't found a clear way to distinguish between iPhone and Apple Watch when pushing updates.

Hello, I am updating my live activity for the new ios18 Smart Stack functionality. I got it working through the WWDC session (Bring your live activities to Apple watch). I'm doing supplementalActivityFamilies([.small]) and then a custom layout in the .small ActivityFamily However, any images I try to use in the Smart Stack just show up as grey squares. (it works on the phone live activity) I suspect it's because my app images are not moved over to the watch? Because I don't have a watch app and such no watch target? If anyone can help me understand if there's anything I can do in order to have a custom image show up on the smart stack, I'd be very grateful.

We are currently experiencing the following weird issue with our iPhone app. As the title says, NSUserDefaults is losing our custom keys and values when phone is rebooted but not unlocked, and this is happening on a very specific scenario with ActivityKit. Context: We are using the NSUserDefaults in the app to store user data (e.g. username). Issue: An error occurred with no permission to access cached messages after a restart. Scenario: When receiving a Dynamic Island notification, if the phone is restarted, after unlocking the phone and tapping on the Dynamic Island to open the App, all cached information results in an error. Reasons for the error: After restarting the APP, the files are in a locked state. The Dynamic Island proactively invokes the App method. When executing the startup method and retrieving cached messages, an error occurs due to lack of permission. All storage, including files, NSUserDefaults, Keychain, and Plist retrieval, results in errors. The error message is as follows: { "errorCode": "-25308", "errorDesc": "Error Domain=com.samsoffes.sskeychain Code=-25308 "(null)"", "serviceName": "com.qunar.qunarclient8", "account": "iid" } The data returned at this time is in a protected state, [UIApplication sharedApplication].isProtectedDataAvailable. Any help or idea will be truly appreciated :)

I want to add Live Activities to my e-commerce app to show the estimated delivery ETA when an order is out for delivery, with the Live Activity initiated from the server. Issue 1: How can I consistently obtain a pushToStart token when a user logs in to my e-commerce app? Currently, I’m considering starting and ending a dummy Live Activity to retrieve the token. Is there a better way to trigger pushToStartTokenUpdates and send the token to my server? Issue 2: How do I properly invalidate the pushToStart token when a user logs out, ensuring the next user doesn’t inherit the same token? Ideally, I don't want the user to wait until the token is automatically invalidated before logging out.

In the app's Live Activity, Text (timerInterval:) is well displayed on Dynamic Island, but there seems to be a bug in Live Activity (Smart Stack in watchOS) that automatically transfers from iOS 18 to watchOS 11. Does anyone know about this?

Hi, I'm updating our app to use Xcode 16 and Swift 6 language mode. I'm stuck on updating our live activity code. I looked at the Emoji Rangers sample project and after switching it to Swft 6 mode, it has the exact same errors as our project. The main problem seems to be that Activity is not Sendable, which prevents us from passing it to child tasks to await things like activityStateUpdates and contentUpdates (those are also not Sendable). Is there any guidance on this? Updated sample code? Another project?

I have an app that starts a Live Activity on a certain user action. This Live Activity contains a button that the user can tap, which updates a SwiftData model instance. However, when you return to the main app after tapping the button on the Live Activity, the views do not update to reflect the changes, even though the changes were written to the database. The underlying issue here is that the ModelContainer/ModelContext used by the AppIntent (performed from the LiveActivity when the button is tapped), are different from the instances in the main app. Meaning that while the changes are written to the underlying storage, the in-memory instances of ModelContext/ModelContainer in the main app don't get the changes from the extension, so SwiftUI doesn't update either. What is the recommended way to handle this scenario? Or is there one? :) Shared access to a SwiftData container is clearly supported through App Groups, so is there not a mechanism to ensure changes made by an extension are updated in real-time for the main app? Otherwise, it seems I would have to go through and manually rerun queries that views depend on to make sure they are showing the most recent data. This is cumbersome and error-prone. Perhaps I'm missing something? Any suggestions would be greatly appreciated.

I have defined a colour in the asset catalog of my widget extension. I am using this widget extension for my live activity. This colour has both an ‘Any’ and ‘Dark’ appearance. I am using this colour in the activityBackgroundTint modifier for my main live activity view (the ActivityPreviewViewKind is content, visible on the Lock Screen). In light mode, this works as expected, but in dark mode, the background colour is still the light mode variant. The content within the view changes according to whether the system is in light or dark mode, but the background does not. I want to avoid using just the background modifier instead of activityBackgroundTint, as this does not colour the ‘Allow Live Activities from …’ and ‘Clear’ sections, which is undesirable. I have also tried reading colorScheme from the environment and choosing the light or dark mode colour variant accordingly, but this workaround also doesn’t completely work. If you keep changing from light and dark mode (via the Settings app, not the control centre, for whatever reason), the background colour actually becomes the opposite of the expected value in this case. Is there a workaround that can help me achieve what I want, or am I simply doing something wrong? I have filed a bug report under FB15148099

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.
