Hi I am experiencing the same problem. Can someone help me I tryed all the thing that you made but it doestn seem to fix anything. Help!

I managed to help my self! This was the code of the picker view did select row: func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) { optionsField.text = options[row] optionsField.resignFirstResponder() let vcName = identities[row] let viewController = storyboard?.instantiateViewController(identifier: vcName!) viewController?.navigationItem.largeTitleDisplayMode = .never self.navigationController?.pushViewController(viewController!, animated: true)} And this is the code now: if row == 0 { color = UIColor.red let alert = UIAlertController(title: "Error", message: "Please Choose Something", preferredStyle: UIAlertController.Style.alert) } And I removed the identities var from the above code. Hope this helps someone!

O and this is still there too: optionsField.text = options[row] optionsField.resignFirstResponder() for the textfield.

Hi friend, I managed to fix the problem for my self. Have you tried to change the preview device? If that doesn't work try restarting xcode and then changing the preview device. It worked for me. Hope it worked for you too.
