Firebase: When Sign In failed, how to get the error code?

I have coded a service use to sign-in users: 

func login(email: String, password: String) -> Bool {

    var userIsConnected = false

    Auth.auth().signIn(withEmail: email, password: password) { (user, error) in

        if error != nil {

            print(type(of: error)) // Print 'NSError'
            print(error!)
        }

        else {

            userIsConnected = true
        }
    }
    return userIsConnected
}

When I print the error I get:

Error Domain=FIRAuthErrorDomain Code=17008 "The email address is badly formatted." UserInfo={NSLocalizedDescription=The email address is badly formatted., error_name=ERROR_INVALID_EMAIL}

How can I get the Code value (17008) to be able to do some custom behaviour ?

Note: In a previous version of FirebaseAuth we can simply do error.code but in the last version we can't.

The type of error is Error and Error can be casted to NSError.

if let error = error, (error as NSError).code == 17008 {
    // do something
}

TRY error?.localizedDescription 

    // to show error through alert controller
    let alertController = UIAlertController(title: "your title", message: error?.localizedDescription, preferredStyle: .alert)

    let defaultAction = UIAlertAction(title: AlertActionTitle, style: .cancel, handler: nil)
    alertController.addAction(defaultAction)
    self.present(alertController, animated: true, completion: nil)
