I have a similar question like the guy in this thread How to get from SKScene to UIViewController?. First I should say I'm a totally beginner and it's all new for me.
My main menu (the first screen when my app did load) is here:
class MenuVC: UIViewController {
... }
The interactions of my app (game) could be made here:

class GameScene: SKScene {
//let storyboard = UIStoryboard(name: "Main", bundle: nil)
//let MenuVC = storyboard.instantiateViewController(withIdentifier: "MenuVC")
//MenuVC.view.frame = (self.view?.frame)!
//MenuVC.view.layoutIfNeeded()
//UIView.transition(with: self.view!, duration: 0.3, options: .transitionFlipFromRight, animations:
//{

@IBAction func backToMainMenu(_ sender: Any) {
//self.view?.window?.rootViewController
self.view?.window!.rootViewController?.dismiss(animated: false, completion: nil)
}
}
In my function "backToMainMenu" I try to go back to the MenuVC but I get a warning "Expression of type 'UIViewController?' is unused" and if I try it in the simulator the simulator will crash.
I'm thankful for every kind of help :).
