# timer(duration:attributes:stopIntent:secondaryIntent:sound:) Creates a configuration that behaves like a traditional timer. ``` static func timer(duration: TimeInterval, attributes: AlarmAttributes, stopIntent: (any LiveActivityIntent)? = nil, secondaryIntent: (any LiveActivityIntent)? = nil, sound: AlertConfiguration.AlertSound = .default) -> AlarmManager.AlarmConfiguration ``` ## Parameters `duration` The duration of the timer in seconds. `attributes` The attributes to use when presenting the alert. `stopIntent` The intent to execute when a person stops the timer. `secondaryIntent` The intent to execute when a person taps the secondary button. `sound` The sound to play when the alarm fires. ## Discussion The timer starts immediately, runs for `duration` seconds, and then alerts. If you provide a secondary button with a behavior that indicates that the timer can repeat, the alert has a repeat button. --- Copyright © 2026 Apple Inc.
