로그인 화면 구현

• 뷰 컨트롤러 간 값 전달하기 FirstViewController.swift (값을 입력받을 뷰)

      @IBAction func LoginAction(_ sender: UIButton) {
          guard let loginViewController = self.storyboard?.instantiateViewController(identifier: "LoginViewController") as? LoginViewController else { return }
          
          loginViewController.idText = idTextField.text
          loginViewController.pwText = pwTextField.text
          
          loginViewController.modalPresentationStyle = .fullScreen
          
          self.present(loginViewController, animated: true, completion: nil)
      }

  LoginViewController.swift (값을 전의 뷰컨에서 받아올 뷰)

      var idText: String?
      var pwText: String?
  
      private func setTextField() {
          guard let idText = self.idText else { return }
          guard let pwText = self.pwText else { return }
          
          finalIdTextField.text = idText
          finalPwTextField.text = pwText
          
      }

• 마지막 뷰에서 처음 뷰로 한번에 dismiss LoginViewController.swift

      @IBAction func LogoutAction(_ sender: UIButton) {
          
          let navigationController = self.presentingViewController as? UINavigationController
  
          self.dismiss(animated: true) {
            let _ = navigationController?.popToRootViewController(animated: true)
          }
          
      }
