未解決の識別子 "winnerLabel"の使用

Question

2つの異なる変数の未解決の識別子を取得しています。 viewControllerクラスの変数を定義しましたが、何らかの理由でviewDidLoad（）関数に変数を追加するとエラーが発生します。助言がありますか？前もって感謝します！私はあなたの中括弧をチェックし、新しいXcodeのV8ベータで6

class ViewController: UIViewController {  
    @IBOutlet weak var playAgainButton: UIButton! 
    @IBOutlet weak var winnerLabel: UILabel!
