Apple Developer

Apple introduces AlarmKit, a new iOS framework that enables developers to create custom alarms within their apps. The framework supports both countdown timers and scheduled alarms that break through silent mode and focus settings. Key features include custom Live Activities for countdown interfaces, integration with Lock Screen and Dynamic Island, custom alarm buttons with App Intents, and system-wide alarm management. Developers need user authorization and can customize alarm appearance, sounds, and actions while maintaining full lifecycle control over scheduled alarms.
