Populate textfield.text after segue

Question

I have a show-type segue. I want destinationViewController nameTextField to contain some text in it when segue is performed. I tried doing:

override func prepare (for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "ToEditScreen" {
     
        let svc = segue.destination as! EditViewController
        svc.nameTextField.text = cars[selectedIndex!].name //crashes
        svc.nameString = cars[selectedIndex!].name
        }
    }

The error I get is: Unexpectedly found nil while implicitly unwrapping an Optional value.
I know that cars[selectedIndex!].name is not nil.
If I delete the textfield line everything is fine and nameString does get its value which is equal to cars[selectedIndex!].name. I know I can do:

nameTextField.text = randomString

but it seems like an extra step. Can I populate textfield.text from original ViewController?

Answer 1

You can add a string variable to the destination vc and set it there or

let svc = segue.destination as! EditViewController
svc.loadViewIfNeeded() // add this line
svc.nameTextField.text = cars[selectedIndex!].name
