# AlarmManager.AlarmConfiguration An object that contains all the properties necessary to schedule an alarm. ``` struct AlarmConfiguration where Metadata : AlarmMetadata ``` ## Overview Pass the schedule or countdown and any attributes you define to the `AlarmConfiguration` for the system to schedule. You can pass in an optional secondary intent that the system executes when a person taps a secondary button. This is only available after first unlock. You can also include custom sounds for your alarm. The following example configures an alarm with a countdown duration. ```swift let configuration = AlarmManager.AlarmConfiguration( countdownDuration: Alarm.CountdownDuration(preAlert: 10, postAlert: 10), schedule: nil, attributes: attributes, secondaryIntent: repeatIntent, alertConfiguration: AlertConfiguration( title: "Eggs are ready!", body: "Time to eat!", sound: .default)) ``` ## Topics ### Configuring a scheduled alarm [`alarm(schedule:attributes:stopIntent:secondaryIntent:sound:)`](/documentation/AlarmKit/AlarmManager/AlarmConfiguration/alarm(schedule:attributes:stopIntent:secondaryIntent:sound:)) ### Configuring a countdown [`init(countdownDuration:schedule:attributes:stopIntent:secondaryIntent:sound:)`](/documentation/AlarmKit/AlarmManager/AlarmConfiguration/init(countdownDuration:schedule:attributes:stopIntent:secondaryIntent:sound:)) [`timer(duration:attributes:stopIntent:secondaryIntent:sound:)`](/documentation/AlarmKit/AlarmManager/AlarmConfiguration/timer(duration:attributes:stopIntent:secondaryIntent:sound:)) --- Copyright © 2026 Apple Inc.
