How to make a function play different sounds in Swift - swift

Question

I have 10 different buttons and each button has a unique tag associated with it. All buttons are linked to the same IBAction. I have the function to play different different sounds according to the tag associated with the particular button that is clicked.
import AVFoundation
var myAudio: AVAudioPlayer!
let path = Bundle.main.path(forResource: "sound1", ofType: "wav")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
myAudio = sound
sound.play()
} catch {
//
}
}

Answer 1

do like
#objc func yourbtnActionName(_ sender : UIButton){
switch sender.tag {
case 1:
commonSoundCode(name: "sound1")
break
case 2:
commonSoundCode(name: "yoursecondSoundname")
break
default:
break
}
}
then common method as
func commonSoundCode(name: String){
let path = Bundle.main.path(forResource: name, ofType: "wav")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
myAudio = sound
sound.play()
} catch {
//
}
}
option 2
if your sound files are in the same sequence, for e.g (sound1.wav, sound2.wav......, sound10.wav) then call like
#objc func yourbtnActionName(_ sender : UIButton){
let path = Bundle.main.path(forResource: "sound\(sender.tag)", ofType: "wav")!
let url = URL(fileURLWithPath: path)
do {
let sound = try AVAudioPlayer(contentsOf: url)
myAudio = sound
sound.play()
} catch {
//
}
}

Answer 2

You need to simply play sounds according to the UIButton's tag.
#IBAction func playsound(_ sender: UIButton)
{
switch sender.tag
{
case 0:
//Sound for Button with tag=0
case 1:
//Sound for Button with tag=1
default:
//Default Sound
}
}
In the above code, add more cases according to your UIButton tags.
Please add some more code for a bit more clarity around your question.
