    return (value(forKey: "ForgotPasswordEmailCheck") as? String)!
  }

LoginViewController: 

   @IBAction func forgotPassword(_ sender: Any) {
     
    let mainStoryboard = UIStoryboard(name: "Main", bundle: Bundle.main)
     
    guard let forgotPasswordEmailCheck = mainStoryboard.instantiateViewController(identifier: "ForgotPasswordEmailCheck") as?
    ForgotPasswordEmailCheckController else {
      print("Not correct password")
      return
    }
     
    navigationController?.pushViewController(ForgotPasswordEmailCheckController, animated: true)
  }
