Swift 2 + Xcode 7: Sound playing when wrong button is pressed - ios

Question

I have a problem with a little App I am programming & learning with. I finally added a sound that it's supposed to play when you press a Stepper, and it does, the problem is that it's also playing when you press a different button.
I honestly have no idea why it happens and how to fix it.
Any help?
here's my code:
ViewONE (here the button that shouldn't be playing the audio file is "BotonLetsBegin"

Answer 1

Your issue is in init(...) method of ViewTwo. You create a player and call the play() method :
required init? (coder aDecoder: NSCoder){
super.init(coder: aDecoder)
do {
try audioPlayer = AVAudioPlayer(contentsOfURL: sound, fileTypeHint: nil)
audioPlayer.prepareToPlay()
audioPlayer.delegate = self
audioPlayer.play() // this is your problem ;)
} catch {
// Errors here
}
}
