# scheduledTimer(withTimeInterval:repeats:block:) Creates a timer and schedules it on the current run loop in the default mode. ``` class func scheduledTimer(withTimeInterval interval: TimeInterval, repeats: Bool, block: @escaping @Sendable (Timer) -> Void) -> Timer ``` ## Parameters `interval` The number of seconds between firings of the timer. If `interval` is less than or equal to `0.0`, this method chooses the nonnegative value of `0.0001` seconds instead. `repeats` If `true`, the timer will repeatedly reschedule itself until invalidated. If `false`, the timer will be invalidated after it fires. `block` A block to be executed when the timer fires. The block takes a single `NSTimer` parameter and has no return value. ## Return Value A new `NSTimer` object, configured according to the specified parameters. ## Discussion After `interval` seconds have elapsed, the timer fires, executing `block`. --- Copyright © 2026 Apple Inc.
