ios – loginaction says “please re-type password

That is my viecontroller –

 import UIKit
 import FirebaseFirestore
 import FirebaseAuth
 import Stripe
 import FirebaseFunctions

class SignUpViewController: UIViewController {
var paymentContext = STPPaymentContext()

@IBOutlet weak var e mail: UITextField!
@IBOutlet weak var password: UITextField!
@IBOutlet weak var passwordConfirm: UITextField!
@IBOutlet weak var login: UITextField!

@IBOutlet weak var loginpassword: UITextField!
@IBAction func signUpAction(_ sender: Any) {
    if password.textual content != passwordConfirm.textual content {
        let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
        let defaultAction = UIAlertAction(title: "OK", model: .cancel, handler: nil)
        alertController.addAction(defaultAction)
        self.current(alertController, animated: true, completion: nil)
    }
    else{
        Auth.auth().createUser(withEmail: e mail.textual content!, password: password.textual content!){ [self]
            (person, error) in if error == nil {
                // 👇
                Capabilities.features().httpsCallable("createStripeUser").name(["email": email.text ?? ""]) {
                    (outcome, error) in
                    if let error = error {
                        debugPrint(error.localizedDescription)
                        return
                    }
                    self.dismiss(animated: true)
                }
            }
            else{
                let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
                let defaultAction = UIAlertAction(title: "OK", model: .cancel, handler: nil)
                alertController.addAction(defaultAction)
                self.current(alertController, animated: true, completion: nil)
            }
        }
    }
}
@IBAction func loginAction(_ sender: Any) {
      
Auth.auth().signIn(withEmail: e mail.textual content!, password: password.textual content!) { (person, error) in
   if error == nil{
     self.performSegue(withIdentifier: "loginToHome", sender: self)
                  }
    else{
     let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
     let defaultAction = UIAlertAction(title: "OK", model: .cancel, handler: nil)
                    
      alertController.addAction(defaultAction)
      self.current(alertController, animated: true, completion: nil)
         }
     }
        
    }
  }

The “signUpAction” motion works wonderful however the “loginAction” doesn’t. It says “re-type password whether or not the person is registered or not as proven beneath:-

The firebase and stripe buyer is authenticated as proven within the figures beneath:-

What am a I doing incorrect ?
