How stop SKAction background music - ios

Question

I'm trying to make a game and in the main menu, there is a label to start music, and another to stop music.
let backgroundMusic = SKAction.playSoundFileNamed("background.mp3", waitForCompletion: false)
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
let location = touch.location(in: self)
let touchedNode = atPoint(location)
if touchedNode.name == self.BEGIN_MUSIC {
// start music
self.run(backgroundMusic)
}
if touchedNode.name == self.STOP_MUSIC {
// stop music
SKAction.stop()
}
}
}
the music starts fine and works on all scenes which is what i wanted. But when I press the stop music, the music keeps playing. How do I stop the music.
I've tried SKAction.pause(), i've tried using withKey: "music" and then self.removeAction(forKey: "music").
I also tried making backgroundMusic: SKAudioNode and this worked but once i stopped the music i couldn't turn it back on, also it doesn't work on any other scene just the main menu.
How do I stop the sound?

I've had the same issue a while ago: This is how I got it working. This is specific for background music.
var backgroundMusic: AVAudioPlayer!
func playMusic() {
if let musicURL = Bundle.main.url(forResource: "musicSource", withExtension: "wav") {
if let audioPlayer = try? AVAudioPlayer(contentsOf: musicURL) {
backgroundMusic = audioPlayer
backgroundMusic.numberOfLoops = -1
backgroundMusic.play()
backgroundMusic.volume = 0.2
}
}
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
super.touchesBegan(touches, with: event)
if let touch = touches.first {
let pos = touch.location(in: self)
let node = self.atPoint(pos)
let musicOff = UserDefaults.standard.bool(forKey: "musicOff")
if node == musicButton && musicOff == false {
backgroundMusic.stop()
UserDefaults.standard.set(true, forKey: "musicOff")
}
if node == musicButton && musicOff == true {
backgroundMusic.play()
backgroundMusic.volume = 0.3
UserDefaults.standard.set(false, forKey: "musicOff")
}
}
}
