            return
        }

        print("Email: \(email)")

// MARK: TextFieldViewDelegate
extension ViewController: TextFieldViewDelegate {

    func textFieldView(_ textFieldView: TextFieldView, didValidated isValid: Bool) {

        self.setButton(isValid: isValid)
    }

    private func setButton(isValid: Bool) {
        self.buttonClick.backgroundColor = isValid ? #colorLiteral(red: 0.2196078449, green: 0.007843137719, blue: 0.8549019694, alpha: 1) : #colorLiteral(red: 0.855728209, green: 0.855728209, blue: 0.855728209, alpha: 1)
        self.buttonClick.isEnabled = isValid
    }

    func textFieldViewDidEndEditing(_ textFieldView: TextFieldView) {
        let alertVC = UIAlertController(title: "Finished", message: "is valid: \(textFieldView.isValid)", preferredStyle: .alert)

        alertVC.addAction(.init(title: "Ok", style: .cancel, handler: { _ in

            // TEST
//            if textFieldView.isValid {
//
//                textFieldView.textField.becomeFirstResponder()
//
//            } else {
//
//                textFieldView.textField.resignFirstResponder()
//            }

        }))
