Why can't I call my function with gestureTapRecogniser

Question

I have this simple function that when someone taps the screen, the code inside the function executes, I know the code in the function works and I get no error when it is typed.<

Answer 1

Just change

reload()

to

reload(gestureRecognizer: nil)

and reload method parameter should be UITapGestureRecognizer? optional.

func reload(gestureRecognizer: UITapGestureRecognizer?) {
        let skView = self.view!
        skView.presentScene(scene)
}

Another short way is

change action method that declared with UITapGestureRecognizer

...action: #selector(self.reload())...

means remove (_:) no need to do anythings more just call reload() function.
