Hello,
I'm having an issue with my single view app. The build is succeeded but the excution fails. Here is the main code -- ViewController.swift --:

import UIKit
class ViewController: UIViewController {
@IBOutlet weak var champMessageCodé: UITextField!
@IBOutlet weak var libelléMessageDécodé: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
mettreÀJourMessageDécodé()
champMessageCodé.becomeFirstResponder()
}
@IBAction func champTexteAChangé(_ sender: Any) {
mettreÀJourMessageDécodé()
}
private static func décoder(message messageCodé: String) -> String {
return String(messageCodé.reversed())
}
func mettreÀJourMessageDécodé() {
let texteEntré = champMessageCodé.text ?? ""
let messageDécodé = ViewController.décoder(message:texteEntré)
libelléMessageDécodé.text = messageDécodé
}
}And here is my stacktrace:
2019-09-29 22:05:36.999631+0100 Décodeur[32109:3024886] Unknown class _TtC9Décodeur14ViewController in Interface Builder file.
