[UIView setText:]: unrecognized selector sent to instance

When I run the application and click the Yes button, The application will crash. But the No button working fine. Did anyone know what is the error?

Here is the error:

2019-03-12 23:05:53.139631+0000 surveyPF[81734:12033947] -[UIView setText:]: unrecognized selector sent to instance 0x7fe1c4416eb0
2019-03-12 23:05:53.148796+0000 surveyPF[81734:12033947] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setText:]: unrecognized selector sent to instance 0x7fe1c4416eb0'

And here is my code:

import UIKit

class FirstQViewController: UIViewController {
    var IDtext: String?
    var DateText: String?
    var answer: String?

    @IBAction func viewBtn(_ sender: UIButton) {

        switch sender.tag {
        case 0: answer = "Yes"
            self.performSegue(withIdentifier: "firstSegue", sender: self)
        case 1: answer = "No"
            self.performSegue(withIdentifier: "secondSegue", sender: self)
        default:
            print("Nothing")
        }
    }

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "firstSegue", let dest = segue.destination as? SecondQViewController {
            dest.IDtext = self.IDtext
            dest.DateText = self.DateText
            dest.answer = self.answer
        } else if segue.identifier == "secondSegue", let dest = segue.destination as? ThirdQViewController {
            dest.IDtext = self.IDtext
            dest.DateText = self.DateText
            dest.answer = self.answer
        }
    }
}

In my case the problem was like this (may be helpful for others as well)

  1. We had an old Objective-C class, which subclassed the UITextField:

    @interface CustomTextField: UITextField

  2. On the storyboard, someone set Custom Class CustomTextField on UIView. Somehow this was working fine for years.

  3. But when we migrated CustomTextField to Swift (pretty much one-to-one, no major changes were done), the UIView, which had Custom Class set to CustomTextField started crashing with the same exception:

    [UIView setText:]: unrecognized selector sent to instance ...

So the solution was to replace UIView on the storyboard with the actual UITextField

When you click Yes, you segue to an instance of SecondQViewController. It seems that somewhere in that view controller you are setting the text property of some view that you expect to have a text property (such as a UILabel, UITextField, or UITextView) but your storyboard for that view controller has that view set as a UIView and not the more specific class type.

You need to check the views in the storyboard for the view controller and see which view is set as a plain old UIView instead of a more specific type of view that actually has a text property.
