SpriteKit Pause Resume Error

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let touch = touches.first
let touchLocation = touch!.location(in: self)
if continueButton.contains(touchLocation) {
    scene?.view?.isPaused = false
    pauseMenu.removeFromParent()
    self.addChild(pauseButton)
    self.addChild(upButton)
    continueButton.removeFromParent()
}
}

I am having a Thread 1: Signal SIGABRT error when touches ended on the continue button. Something I have found is that if I declare the sprite (continue button) in touches ended the button does not get removed, however, when I declare the continue button sprite outside the function the continue button is removed.The problem is that sometimes the app will just crash showing the thread 1 error. Any ideas on how I can stop the crashing?

class GameScene: SKScene {
var mainturret = SKSpriteNode(imageNamed: "Main Turret")
var pauseButton = SKSpriteNode(imageNamed: "Pause Simbol")
var angleToShoot = 0
var touchIsOn = 0
var pointTwoSecondInterval = 0
let pauseMenu = SKSpriteNode(imageNamed: "Paused")
var zombieSpawningTimer = Timer()
var upButton = SKSpriteNode(imageNamed: "Up Button")
let downButton = SKSpriteNode(imageNamed: "Down Button")
let popUpMenu = SKSpriteNode(imageNamed: "TurretSpot")
var continueButton = SKSpriteNode(imageNamed: "Continue")
...}

This is where the buttons are declared (outside the functions) 

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

Error occurs on the third line of code. This is what the computer tells me.

The reason is because that you are adding upButton twice as a child to some node.

Most likely, the the line self.addChild(upButton) in your touchesEnded method is causing the issue. At that point, verify if upButton.parent in nil. If not, you have a logical error in your code.
