AudioServicesSystemSoundCompletionProc

Declaration

typealias AudioServicesSystemSoundCompletionProc = (SystemSoundID, UnsafeMutableRawPointer?) -> Void

Parameters

• ssID:

  The system sound that has finished playing.

• clientData:

  App data that you specified when registering the callback function.

Discussion

Because a system sound may play for up to 30 seconds, the AudioServicesPlaySystemSound(_:) function executes asynchronously (that is, it returns immediately), and calls this function when the sound finishes playing. You can use this callback, for example, to help you avoid playing a second sound while a first sound is still playing.
