Hiding UIButton in GameScene

Did you create an IBOutlet for the button ?

if so, just call myButton.isHidden = true

Yes, I did. But what I want is to hide the button in the GameScene.swift, but the UIButton is created in the GameViewController.swift.

You could use notification :

- post notification from GameViewController

- subscribe to notification in GameScene and hide the button in the function called on notification.

Or you can use delegation.
