Load, save high score on second view controller

I am trying to load and save my high score on only the gameOverViewController. I have successfully transferred the score from the secondViewController to the gameOverViewController. The gameOverViewController is like a normal game over screen that shows your score, high score and has retry and main menu button. I tried to set the highScoreLabel equal to the scoreGameOverLabel, it runs, but the highScore int stays at 0 and doesn't equal the gameOverScore. I am trying to:

  1. if score > high score , high score = score

  2. if score < high score, high score remains same 

    var addOne = 0
class SecondViewController: UIViewController
{

@IBOutlet weak var score: UITextField!

score.text = "\(addOne)"

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

let gameOver = segue.destination as! GameOverViewController

gameOver.gameOverText = score.text!
gameOver.lastScore = addOne
}

gameOverViewController 

class GameOverViewController: UIViewController {


@IBAction func retryButton(_ sender: Any) {   
addOne = 0
  highScoreLabel.text = NSString(format: "%i", highScore) as String
} 

@IBAction func mainMenuButton(_ sender: Any) { 
addOne = 0
  highScoreLabel.text = NSString(format: "%i", highScore) as String
}        

var lastScore = 0
var highScore = UserDefaults.standard.integer(forKey: "high_score")  

@IBOutlet weak var highScoreLabel: UILabel!

@IBOutlet weak var scoreGameOverLabel: UILabel!

var gameOver = ""

override func viewDidLoad() {
    super.viewDidLoad()

    if lastScore > highScore {
        highScore = lastScore
       highScoreLabel.text = NSString(format: "%i", highScore) as String
        UserDefaults.standard.set(highScore, forKey: "high_score")
    }                 
    scoreGameOverLabel.text = gameOver       
}

In SecondViewController, try setting your last score.

gameOver.lastScore = addOne

In GameOverViewController add the lastScore variable and keep track of your high score.

var lastScore = 0
var highScore = UserDefaults.standard.integer(forKey: "high_score")

if lastScore > highScore {
    highScore = lastScore
    UserDefaults.standard.set(highScore, forKey: "high_score")
}

Firstly,

highScoreLabel = scoreGameOverLabel

Should probably be

 highScoreLabel.text = scoreGameOverLabel.text

Secondly, as per your snippet, in GameOverViewController there is no addOne, how are you setting it and using it to compare in If condition ?
