Build real-time, glanceable experiences on the Lock Screen, Dynamic Island, StandBy, CarPlay, and a paired Mac using ActivityKit. Patterns target iOS 26+ with Swift 6.3, backward-compatible to iOS 16.1 unless noted.
See references/activitykit-patterns.md for complete code patterns including push payload formats, concurrent activities, state observation, and testing.
