live-activities
Real-time Lock Screen and Dynamic Island widgets for iOS using ActivityKit.
- Define
ActivityAttributeswith static data and dynamicContentState; start activities withActivity.request(), update withactivity.update(), and end withactivity.end() - Design three Dynamic Island presentations: compact (icon + one value), minimal (single glyph), and expanded (multi-region layout with leading, trailing, center, bottom)
- Push-to-update via APNs with
pushType: .token, forwarding tokens throughactivity.pushTokenUpdatesand sending JSON payloads matching yourContentStatestructure - Handle stale dates with
context.isStaleto show fallback UI; always end activities to prevent Lock Screen clutter - iOS 26 adds scheduled activities, transient style, Mac menu bar support, and channel-based push for broadcast updates
Live Activities and Dynamic Island
Build real-time, glanceable experiences on the Lock Screen, Dynamic Island, StandBy, CarPlay, and Mac menu bar using ActivityKit. Patterns target iOS 26+ with Swift 6.2, backward-compatible to iOS 16.1 unless noted.
See references/live-activity-patterns.md for complete code patterns including push payload formats, concurrent activities, state observation, and testing.
