Output:

Protocol/Delegate to call a game ViewController method from the game scene

GameScene code example:

import SpriteKit
protocol GameViewControllerDelegate: class {
    func callMethod(inputProperty:String)
}
class GameScene: SKScene {
    weak var gameViewControllerDelegate:GameViewControllerDelegate?
    override func didMove(to view: SKView) {
        gameViewControllerDelegate?.callMethod(inputProperty: "call game view controller method")
    }
}

GameViewController code example:

class GameViewController: UIViewController, GameViewControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            // Load the SKScene from 'GameScene.sks'
            if let scene = SKScene(fileNamed: "GameScene") {
                let gameScene = scene as! GameScene
                gameScene.gameViewControllerDelegate = self
                gameScene.scaleMode = .aspectFill
                view.presentScene(gameScene)

Multiple UIViewController in a game: how to jump from the scene to a viewController

Storyboard:

Initial viewController: an empty viewController with a button to present the GameViewController

GameViewController: the typical GameViewController of the “Hello World” Sprite-kit template.

Goal: I want to present the first viewController from my SKScene game with the correct deallocation of my scene.

Description: To obtain the result I’ve extended the SKSceneDelegate class to build a custom protocol/delegate that make the transition from the GameViewController to the first initial controller (main menu). This method could be extended to other viewControllers of your game.

GameViewController:

import UIKit
import SpriteKit
class GameViewController: UIViewController,TransitionDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        if let view = self.view as! SKView? {
            if let scene = SKScene(fileNamed: "GameScene") {
                scene.scaleMode = .aspectFill
                scene.delegate = self as TransitionDelegate
                view.presentScene(scene)
            }
            view.ignoresSiblingOrder = true
            view.showsFPS = true
            view.showsNodeCount = true
        }
    }
    func returnToMainMenu(){
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        guard  let storyboard = appDelegate.window?.rootViewController?.storyboard else { return }
        if let vc = storyboard.instantiateInitialViewController() {
            print("go to main menu")
            self.present(vc, animated: true, completion: nil)
        }
    }
}

GameScene:

import SpriteKit
protocol TransitionDelegate: SKSceneDelegate {
    func returnToMainMenu()
}
class GameScene: SKScene {
    override func didMove(to view: SKView) {
        self.run(SKAction.wait(forDuration: 2),completion:{[unowned self] in
            guard let delegate = self.delegate else { return }
            self.view?.presentScene(nil)
            (delegate as! TransitionDelegate).returnToMainMenu()
        })
    }
    deinit {
        print("\n THE SCENE \((type(of: self))) WAS REMOVED FROM MEMORY (DEINIT) \n")
    }
}
