Answer 1

Swift 4

Set delegate of UITextField in view controller, field.delegate = self, and then:

extension ViewController: UITextFieldDelegate {
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        // don't force `endEditing` if you want to be asked for resigning
        // also return real flow value, not strict, like: true / false
        return textField.endEditing(false)
    }
}
