AlarmKit

Framework for scheduling alarms and countdown timers with custom UI, Live Activities integration, and focus/silent mode override. Prevents the most common mistakes: using the wrong authorization property name, omitting the Info.plist key, and forgetting the widget extension for countdown presentations.

When This Skill Activates

Use this skill when the user:

Asks to add, fix, or review alarm or timer functionality
Mentions AlarmKit, AlarmManager, or AlarmPresentation
Wants to schedule one-time, repeating, or countdown alarms
Asks about snooze, stop, or repeat buttons on alarm alerts
Wants alarms to appear on Dynamic Island or Lock Screen (Live Activities)
Mentions overriding Focus or silent mode for alarms
Asks about AlarmAttributes or AlarmMetadata

Decision Tree

Choose the right reference file based on what the user needs:

What do you need?
|
+-- Schedule an alarm (one-time, repeating, or timer)
|   --> scheduling.md
|       +-- One-time alarm: Alarm.Schedule.relative + .repeats: .never
|       +-- Repeating alarm: Alarm.Schedule.relative + .repeats: .weekly(weekdays)
|       +-- Countdown timer: CountdownDuration (no schedule)
|       +-- Authorization & Info.plist setup
|       +-- Managing alarms: pause, resume, cancel
|
+-- Customize alarm UI (alert, countdown, paused screens)
|   --> presentation.md
|       +-- AlarmPresentation.Alert: title, stop, snooze/repeat buttons
|       +-- AlarmPresentation.Countdown: title, pause button
|       +-- AlarmPresentation.Paused: title, resume button
|       +-- Custom buttons with AlarmButton
|       +-- Tint color and metadata via AlarmAttributes
|
+-- Show alarm on Dynamic Island / Lock Screen
