Picker selbst gegeben einen Thread 1 Fehler

Question

Ich bin neu in der Codierung und ich liebe es, ich versuche, einen Picker zu verwenden, aber ich bekomme diesen Fehler. Ich habe genau das gleiche gemacht, was ich in meinem anderen Projekt gemacht habe, aber jetzt funktioniert es nicht ... Kann das passieren, weil ich mehr als 1 View-Controller habe?

ihr mein Code ist, ist der Fehler im Bild habe ich

Fügen Sie einfach UINavigationControllerDelegate wie folgt aus:

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource,UINavigationControllerDelegate { 
}
