找到一个最大值可以为我提供Optional()

当试图在数组中找到最高编号并将其显示在标签上时,我得到了带有Optional()的解决方案。我要怎么做也导致这种情况,如何在标签中没有Optional()的情况下显示我的解决方案。

class ViewController: UIViewController {
@IBOutlet weak var game1: UITextField!
@IBOutlet weak var game2: UITextField!
@IBOutlet weak var game3: UITextField!

@IBOutlet weak var series: UILabel!
@IBOutlet weak var average: UILabel!
@IBOutlet weak var high: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

}

@IBAction func calculate(_ sender: Any) {

   guard
            let text1 = game1.text,
            let text2 = game2.text,
            let text3 = game3.text
    else { return }

    guard
            let game1Results = Int(text1),
            let game2Results = Int(text2),
            let game3Results = Int(text3)
    else { return }

    let gameResultsArray = [game1Results, game2Results, game3Results]

    high.text = "\(String(describing: gameResultsArray.max()))"
}
