Answer 1

create reference of GameViewController in GameScene class like this way

class GameScene: SKScene, SKPhysicsContactDelegate {

    var referenceOfGameViewController : GameViewController!

}

in GameViewController pass the reference like this way

   class GameViewController: UIViewController {

       override func viewDidLoad() {
      super.viewDidLoad()

    if let view = self.view as! SKView? {
    // Load the SKScene from 'GameScene.sks'
     if let scene = GameScene(fileNamed: "GameScene") {
            // Set the scale mode to scale to fit the window
            scene.scaleMode = .aspectFill
            scene.referenceOfGameViewController = self
            // Present the scene
            view.presentScene(scene)
        }


    view.ignoresSiblingOrder = true

    view.showsFPS = true
    view.showsNodeCount = true
    }
  }
}

by using this line you can pass reference to GameScene class

        scene.referenceOfGameViewController = self

Now In GameScene class you can access all the variable of GameViewController like this way

referenceOfGameViewController.fbButton.hidden = false
referenceOfGameViewController.gameOverPopUP.hidden = false
