Can You help me with this Error?

Question

Hey, I just started making an App with XCode, that should be an Extension for a Game, that I play with my Friends. I started programming it (I watched many tutorials), but now I get this Error. After trying two hours to fix it, I found this Forum.

Here is my code from the NamenEintragenViewController.swift-File:

import UIKit

class NamenEintragenViewController: UIViewController {

    @IBOutlet weak var TextFieldPlayer1: UITextField!
    @IBOutlet weak var TextFieldPlayer2: UITextField!
    @IBOutlet weak var TextFieldPlayer3: UITextField!
    @IBOutlet weak var TextFieldPlayer4: UITextField!
    @IBOutlet weak var TextFieldPlayer5: UITextField!
    @IBOutlet weak var TextFieldPlayer6: UITextField!
    @IBOutlet weak var NextButton: UIButton!
    
    var namen: Namen?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.namen = Namen()
    }
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        self.namen?.player1 = TextFieldPlayer1.text
        
        let windVC = segue.destination as! WindstossViewController
        windVC.namen = self.namen
    }

And here the one from the WindstossViewController-File:

import UIKit

class WindstossViewController: UIViewController {

    @IBOutlet weak var WindstossLabel: UILabel!
    @IBOutlet weak var WindstossPerson: UILabel!
    
    var namen: Namen?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.WindstossPerson.text = "\(namen!.player1 ?? "Fehler")"
    }
}

This is the Error I get:

Answer 2

You have an error when trying to cast a type:

SchlamperichErwachtViewController' (0x109aaf208) to 'Schlamperich.WindstossViewController' (0x109aaf008).

That could be line 23

        let windVC = segue.destination as! WindstossViewController

Where do you segue ? I mean, what is the type of controller you try to segue to ? Probably, it is not a WindstossViewController. So check your segue carefully.

A general comment: in Swify, the names of instances, var,, constant… should use caleCase, so start with lowercase. Uppercase is reserved for classes, struct…

So, change the names of your IBOutlets (in fact use Refactor > Rename to do this, by cmd-click on the name you want to change)

    @IBOutlet weak var textFieldPlayer1: UITextField! 
    @IBOutlet weak var textFieldPlayer2: UITextField! 
    @IBOutlet weak var textFieldPlayer3: UITextField! 
    @IBOutlet weak var textFieldPlayer4: UITextField! 
    @IBOutlet weak var textFieldPlayer5: UITextField! 
    @IBOutlet weak var textFieldPlayer6: UITextField! 
    @IBOutlet weak var nextButton: UIButton!
