This sounds like a job for the delegate pattern. Add a protocol for LevelScene;

// LevelScene.swift
protocol LevelScene : class {
    var gameDelegate: GameDelegate? { get set }
}

Add a protocol for GameDelegate;

// GameDelegate.swift
protocol GameDelegate : class {
    func gameOver()
}

In your mainScene add the protocol reference and create a property called gameDelegate;

class MainScene: SKScene, LevelScene {
    weak var gameDelegate: GameDelegate?
}

In your GameViewController add the protocol reference and implement the required protocol function - in this case it's called gameOver and seque to your UIKit View as usual;

class GameViewController: UIViewController, GameDelegate {
    func gameOver() {
        self.performSegue(withIdentifier: ExitGameSegueKey, sender: self)
    }
}

Set the delegate to gameViewController when presenting the scene;

scene.gameDelegate = self

Then in mainScene call the delegate function when required;

self.gameDelegate?.gameOver()
