Using Swift

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 --:

 //

// ViewController.swift
// Décodeur
//

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.

Check your outlet connection for libelléMessageDécodé in Interface Builder. Also, check if the XIB's class is set to ViewController.

This is the problem. Interface builder references a class that does not exist in your source. Voici le problème. Interface Builder fait référence à une classe qui n’existe pas dans votre code source.
Presumably your module name is Décodeur? In that case, you probably have done nothing wrong. It is just that Xcode handles the “é” poorly. Je présume que votre module s’appelle Décodeur ? En ce cas, vous avez probablement fait aucune erreur. C’est juste que Xcode se laisse confondre par le « é ».
You can help Xcode along by making sure the “é” is always encoded the same. There are two ways to encode it: “e” (U+0065) + “◌́” (U+0301) or “é” (U+00E9). Vous pouvez aider Xcode un peu en faisant attention que le « é » soit toujours encodé le même. Il y a deux façons de l’encoder : « e » (U+0065) + « ◌́ » (U+0301) ou « é » (U+00E9).
Or you could choose a different name that does not contain any characters beyond ASCII (sadly). Ou vous pouvez choisir un autre nom, qui ne contient pas de caractère hors de ASCII (malheureusement).
