Could not cast in func prepare for segue

[bonyadmitr]

Steps to reproduce

1. start project
2. make injection with saving file
3. make any push VC with implemented func prepare(for segue: , sender: ) and force cast in it. (see code and screenshots)
4. error

Code:

import UIKit

class QController: UIViewController {
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "QQQ" {
            let vc = segue.destination as! ViewController
            vc.view.backgroundColor = UIColor.black
        }
    }
    
}

class ViewController: UITableViewController {
    
    @IBOutlet weak var someView: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
//        someView.backgroundColor = UIColor.green
//        someView.layer.cornerRadius = 30
//        someView.layer.borderWidth = 10
//        someView.layer.borderColor = UIColor.red.cgColor
    }
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 50
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        cell.textLabel?.text = "Row \(indexPath.row + 1)"
//        cell.textLabel?.font = UIFont.systemFont(ofSize: 30)
//        cell.layer.borderWidth = 3
//        cell.layer.borderColor = UIColor.magenta.cgColor
        return cell
    }
}

Error:

Could not cast value of type 'InjectionTest.ViewController' (0xb0de8) to 'InjectionTest.ViewController' (0xdb07314).

This is a known problem I’m afraid with casting a class that has been injected.

Do you have any plans to fix it? I think it is very important.

Run into this situation too. Steps to reproduce:

1. start xcode
2. modify swift code of a view controller create from storyboard
3. inject source file
4. Recreate this controller from storyboard and force cast to its type.

You have to keep the definition of classes you are instantiating separate from classes you are injecting.
