Swift AVAudioPlayer Restart from Beginning

Question

I have an AVAudioPlayer stored in a property called "player". When the user clicks a button, it triggers this code:

@IBAction func restartPressed(sender: AnyObject) {
    player.play()
}

The problem is happening when the user clicks the button twice in a row very quickly.

If the sound from the first click is still playing, it seems like the second call is ignored.

Instead, I'd like to either:

a) restart the player from the beginning when the button is clicked a second time; or

b) have two "instances" of the sound playing at the same time.

How would I go about achieving either or both of these options?

Answer 1

Answering to "either" part (rather than "both") of these options: (a) how to stop and play the sound from beginning:

@IBAction func restartPressed(sender: AnyObject) {
    if player.playing {
        player.pause()
    }
    player.currentTime = 0
    player.play()
}

Regarding (b): from the Language Ref for AVAudioPlayer:

Using an audio player you can:

...

• Play multiple sounds simultaneously, one sound per audio player, with precise synchronization.

So you'd need two separate players to simultaneously (off-sync) play two separate sounds, even if both players use the same sound. I'd stick with (a).
