FAQPage Schema
How do I create a Live Activity and Dynamic Island UI in iOS?▼

Create a Live Activity by defining ActivityAttributes with static data and a nested ContentState, assembling ActivityContent payloads, and calling Activity.request with a pushType to enable Dynamic Island and Lock Screen UI updates.

How do I update Live Activities with push notifications on the Lock Screen?▼

Update Live Activities using push-to-update flows by configuring the request with a pushType, allowing remote push notifications to continuously refresh time-sensitive UI while the app is suspended or backgrounded.

What is the difference between ActivityAttributes and ContentState in ActivityKit?▼

ActivityAttributes define static data that remains constant for the activity's lifetime, while the nested ContentState holds dynamic data that continuously updates to refresh real-time UI across app lifecycles.

Can I use ActivityKit to update time-sensitive UI while my iOS app is suspended?▼

Yes, ActivityKit supports updating time-sensitive UI while the app is suspended by using push-type or scheduled start methods with proper lifecycle management to continuously refresh Live Activities.

What layout configurations does Dynamic Island support for Live Activities?▼

Dynamic Island supports compact, minimal, and expanded layouts, alongside Lock Screen and StandBy configurations, providing various glanceable UI presentation patterns for time-sensitive updates.

When should I use Live Activities instead of standard push notifications?▼

Use Live Activities for scenarios like delivery tracking, sports scores, and live event progress where the UI must continuously refresh time-sensitive information, rather than standard push notifications for transient alerts.
