Your widget extension’s life cycle is also separate. Live Activity life cycles aren’t tied to the host app’s process, so they’ll stay if the app is force quit. When an app is force quit, is the associated Live Activity dismissed? Alternatively, the activityStateUpdates async sequence will announce a new state if your app already has a reference to the Live Activity. The Activity.activityUpdates static var is an async sequence that will announce updates to all of your app’s Live Activities, including ones that get dismissed.

How can my app detect when someone dismisses a Live Activity? Alternatively, you can choose to dismiss the Live Activity immediately or after a certain time has passed. When ending a Live Activity, you can provide an ActivityUIDismissalPolicy to tell the system when to dismiss your UI. What are the guidelines for dismissing a Live Activity after it ends? You can read more below:ĭisplaying live data with Live Activities The 4-hour default to dismiss a Live Activity is too long for my use case. Keep in mind that these background tasks aren’t processed immediately by the system. You can also use BGProcessingTask and background pushes to provide less frequent updates to your Live Activity. Your app can use a pre-existing background runtime functionality, such as Location Services, to provide Live Activity updates as you see fit. How do I update a Live Activity without using Apple Push Notification service (APNs)? Here are a few highlights from those conversations, including guidance about sizing and styling, when to dismiss a Live Activity, and why widgets and Live Activities are different (except when they’re not). What’s more, thanks to lively features like the Dynamic Island on iPhone 14 Pro and iPhone 14 Pro Max, Live Activities can also be a lot of fun.Īpple evangelists, designers, and engineers came together at Ask Apple to answer your questions about Live Activities and the Dynamic Island. With Live Activities, your app can provide up-to-date, glanceable information - like weather updates, a plane’s departure time, or how long it’ll be until dinner is delivered - right on the Lock Screen.
