TouchesBegan does not work - ios

Question

In the last label lblTryAgain I want to return to another class named GameScene but the tap action does not enter to the function touchesBegan.
I am just following a tutorial to learn how to create games with SpriteKit if someone want to follow the tutorial or see the entire code is available in https://www.raywenderlich.com/87231/make-game-like-mega-jump-sprite-kit-swift-part-1
import SpriteKit
class EndGameScene: SKScene {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(size: CGSize) {
super.init(size: size)
// Stars
let star = SKSpriteNode(imageNamed: "Star")
star.position = CGPoint(x: 25, y: self.size.height-30)
addChild(star)
let lblStars = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
lblStars.fontSize = 30
lblStars.fontColor = SKColor.white
lblStars.position = CGPoint(x: 50, y: self.size.height-40)
lblStars.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.left
lblStars.text = String(format: "X %d", GameState.sharedInstance.stars)
addChild(lblStars)
// Score
let lblScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
lblScore.fontSize = 60
lblScore.fontColor = SKColor.white
lblScore.position = CGPoint(x: self.size.width / 2, y: 300)
lblScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center
lblScore.text = String(format: "%d", GameState.sharedInstance.score)
addChild(lblScore)
// High Score
let lblHighScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
lblHighScore.fontSize = 30
lblHighScore.fontColor = SKColor.cyan
lblHighScore.position = CGPoint(x: self.size.width / 2, y: 150)
lblHighScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center
lblHighScore.text = String(format: "High Score: %d", GameState.sharedInstance.highScore)
addChild(lblHighScore)
// Try again
let lblTryAgain = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
lblTryAgain.fontSize = 30
lblTryAgain.fontColor = SKColor.white
lblTryAgain.position = CGPoint(x: self.size.width / 2, y: 50)
lblTryAgain.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.center
lblTryAgain.text = "Tap To Try Again"
lblTryAgain.isUserInteractionEnabled = true
addChild(lblTryAgain)
}
func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
// Transition back to the Game
let reveal = SKTransition.fade(withDuration: 0.5)
let gameScene = GameScene(size: self.size)
self.view!.presentScene(gameScene, transition: reveal)
}
}

Answer 1

touchesBegan is a override func which only works in self.viewand it will not work in other UIs
try this
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
print("working")
}

Answer 2

make sure isUserInteractionEnabled is checked and the print statement may not work. add or update sceneDidLoad and print isUserInteractionEnabled
