ios – Worth of kind ‘AuthErrorCode’ has no member ‘debugDescription’

That is the code for Fb Login on my app. The app does not launch and throws Worth of kind ‘AuthErrorCode’ has no member ‘debugDescription’ error. Anybody is aware of how I can do away with this?

extension SignInViewController {
    func facebookLogin() {
        let loginManager = LoginManager()
        loginManager.logIn(permissions: [.publicProfile, .email], viewController: self) { (loginResult) in
            swap loginResult
            {
            case .cancelled:
                self.current(UIAlertController.errorAlert(with: "Cancelled"), animated: true, completion: nil)
                break
            case .failed(let error):
                print(error.localizedDescription)
                self.current(UIAlertController.errorAlert(with: error.localizedDescription), animated: true, completion: nil)
                break
            case .success(let grantedPermission, let declinedPermission, let token):
                print("the grandted permissions (grantedPermission)")
                print("the declined  permissions (declinedPermission)")
                print("the token is (token)")


                let credential = FacebookAuthProvider.credential(withAccessToken: token.tokenString)


                MBProgressHUD.showAdded(to: self.view, animated: true)
                // get Fb person info
                self.getFacebookInfo({ (appUser) in
                    if let appUser = appUser {
                        // login Firebase with Fb
                        OAuthProvider.credential(withProviderID: "fb.com", idToken: token.tokenString, rawNonce:self.randomNonceString())
                        Auth.auth().signIn(with: credential) { (consequence, error) in
                            if let error = error {
                                    MBProgressHUD.conceal(for: self.view, animated: true)
                                    let castedError = error as NSError
                                let firebaseError = AuthErrorCode(AuthErrorCode.Code(rawValue: castedError.code) ?? <#default worth#>)
                                if firebaseError != nil {
                                    print(firebaseError.debugDescription)
                                }
                                self.current(UIAlertController.errorAlert(with: "Signin was failed. n(error.localizedDescription)"), animated: true, completion: nil)
                                return
                            }
                            appUser.userId = consequence?.person.uid
                            self.signedInWithFacebook((consequence?.person)!, appUser: appUser)
                            MBProgressHUD.conceal(for: self.view, animated: true)
                        }
                    } else {
                        MBProgressHUD.conceal(for: self.view, animated: true)
                        self.current(UIAlertController.errorAlert(with: "Cancelled"), animated: true, completion: nil)
                    }
                })

            }
        }
    }

And the app does not construct due to the beneath error:

if firebaseError != nil {
print(firebaseError.debugDescription)
}

Any assist with this may be a lot appreciated.
