AlarmKit

Schedule prominent alarms and countdown timers that surface on the Lock Screen, Dynamic Island, StandBy, and a paired Apple Watch when the alarm fires. AlarmKit requires iOS 26+ / iPadOS 26+. Alarms can break through Focus and Silent mode.

AlarmKit uses ActivityKit data models for its Live Activity, but the firing alert is system-managed alarm UI, not a general custom notification UI surface. Custom UI belongs only to countdown and paused Live Activity states rendered by a Widget Extension with the same AlarmAttributes<Metadata> and AlarmPresentationState used when scheduling.

See references/alarmkit-patterns.md for complete code patterns including authorization, scheduling, countdown timers, snooze handling, and widget setup.
