Sprite Kit Scene won't present

I am currently working on a game that consists of three scenes, the GameScene, ArcheryScene, and GameOverScene. When I start the game the GameScene presents just fine, then I tap on the screen to start the game and the ArcheryScene presents just fine. The GameOverScene gets triggered when a contact is made in the game, and it works as well. However, once the GameOverScene is presented I would like to be able to tap on the screen to go back to the ArcheryScene and restart the game. However when I tap on the screen, nothing happens, at all. Any advice or suggestions would be great appreciated, thank you.

GameScene Code that presents the ArcheryScene when tapped: (works)

import UIKit
import SpriteKit

class GameScene: SKScene {

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */

    }

    override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        /* Called when a touch begins */

    let welcomeNode = childNodeWithName("welcomeNode")

        if (welcomeNode != nil) {
            let fadeAway = SKAction.fadeOutWithDuration(1.0)

            welcomeNode?.runAction(fadeAway, completion: {
                let doors = SKTransition.pushWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let archeryScene = ArcheryScene(fileNamed: "ArcheryScene")
                archeryScene.scaleMode = .AspectFill
                self.view?.presentScene(archeryScene, transition: doors)
            })
        }

    }

    override func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
    }
}

ArcheryScene code that presents the GameOverScene when a contact is made: (works)

let fadeOut = SKAction.sequence([SKAction.waitForDuration(3.0)])
            let welcomeReturn = SKAction.runBlock({
                let Transition = SKTransition.revealWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let gameOverScene = GameScene(fileNamed: "GameOverScene")
                gameOverScene.scaleMode = .AspectFill
                self.scene!.view?.presentScene(gameOverScene, transition: Transition)
            })
            let sequence = SKAction.sequence([fadeOut, welcomeReturn])
            self.runAction(sequence)

GameOverSceneCode that presents the ArcheryScene when tapped: (doesn't work)

import UIKit
import SpriteKit

class GameOverScene: SKScene {

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */

    }

   override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        /* Called when a touch begins */

        let gameOverNode = childNodeWithName("gameOverNode")

        if (gameOverNode != nil) {

            let fadeAway2 = SKAction.fadeOutWithDuration(1.0)

            gameOverNode?.runAction(fadeAway2, completion: {
                let doors2 = SKTransition.pushWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let archeryScene = ArcheryScene(fileNamed: "ArcheryScene")
                archeryScene.scaleMode = .AspectFill
                self.view?.presentScene(archeryScene, transition: doors2)
            })
        }

    }

    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame is rendered */
    }
}

gameOverNode doesnt exist. Youre saying let gameOverNode = childNodeWithName("gameOverNode").. gameOverNode is nil! It's nothing, and so that block of code in the conditional statement isnt doing anything.

you need to add a node named "gameOverNode" in order to reference it. childNodeWithName references a node that already exists in your scene.. its not creating a new one.
