The code works perfectly fine until the countdown timer hits 0.10, in which the simulator will freeze, and Xcode will display this message:

Next to the message would be a line of code that says "@main"

I had expected the app to display a new screen that shows the number of clicks and the clicks per second of the user instead of freezing and displaying this message in AppDelegate.swift.
I can't seem to find the cause of the error, I have compared the section of the code with the variable clicksPerSecond in the NewViewController.swift file with the section of the code in the tutorial code, and they seem to be identical.
I have tried to redo the IBOutlet concerned with the variable clicksPerSecond, and the error still occurs.
Code for NewViewController:

import UIKit

class NewViewController: UIViewController {
    
    var clicks: Int?
    var allocatedTime: Double?

    @IBOutlet weak var clicksLabel: UILabel!
    @IBOutlet weak var clicksPerSecondLabel: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        clicksLabel.text = "You got \(clicks!) clicks"
        clicksPerSecondLabel.text = "Your clicks per second was \(String(format: "%.2f", Double(clicks!)/allocatedTime!))"
    }
