Ok Thank you. Appreciate your help.

That’s awesome OOPer, thank you. So simple.I am trying studying different design patterns and trying to achieve the same thing using a protocol. I’m just stabbing in the dark this time. Below is my clumsy attempt and of course Xcode is yelling. How can I make this work? Thanks in advance again.import SpriteKitimport GameplayKitprotocol KeepScore { var score: Int {get set} var scoreLabel: String {get set}}extension KeepScore { mutating func updateScore(count: Int) { score += 1 let scoreLabel = SKLabelNode(fontNamed: "Arial") scoreLabel.text = "score: \(score)" } func currentScore() -> Int { return score } }class GameScene002: SKScene, KeepScore { var scoreLabel = "score: Score" var score = 0 override func didMove(to view: SKView) { self.anchorPoint = .zero self.backgroundColor = SKColor.green let scoreLabel = SKLabelNode(fontNamed: "Arial") scoreLabel.fontSize = 35 scoreLabel.text = "Score: Score" scoreLabel.fontColor = SKColor.black scoreLabel.position = CGPoint(x: scene!.size.width/2.0, y: scene!.size.height/2.0) scoreLabel.zPosition = 5 self.addChild(scoreLabel) } func updateScore() { score += 1 let scoreLabel = SKLabelNode(fontNamed: "Arial") scoreLabel.text = "score: \(score)" } override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { updateScore() if score == 5 { let transition = SKTransition.fade(withDuration: 2.0) let scene02 = Scene02(size: size) view?.presentScene(scene02, transition: transition) } } override func update(_ currentTime: TimeInterval) { updateScore() }}import SpriteKitimport GameplayKitclass Scene002: SKScene, KeepScore { var scoreLabel: String = "Score: Score" var score = 0 var currentScore = 0 override func didMove(to view: SKView) { self.anchorPoint = .zero self.backgroundColor = SKColor.red currentScore() } }
