in swift source Type of expression is ambiguous without more context

func touchesBegan(touches: NSSet, withEvents event:UIEvent) {  
    for touch: AnyObject in touches {
        let location = touch.locationInNode(self)
        player.position.x = location.x
    }
}

it gives me this following error

Type of expression is ambiguous without more context

>Solution :

This looks like Swift 2 code. The current signature is

func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
  for touch in touches {
        let location = touch.locationInNode(self)
        player.position.x = location.x
    }
}

And if we are talking about Swift 2 then cast NSSet to native Set and it’s certainly withEvent (singular)

func touchesBegan(touches: NSSet, withEvent event:UIEvent) {  
    for touch in touches as Set<UITouch> {
