is there any way to throw an error from firebase login to error handling?

I have created a helper class with the following method:

func setupAlert(with title: String, with message: String?, viewController: UIViewController) {
            let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
            let cancel = UIAlertAction(title: "OK", style: .cancel, handler: nil)
            viewController.present(alert, animated: true, completion: nil)

you must pass the viewcontroller in the parameter where you want to display the alert. Then you can also pass the error, which can be found in Auth.auth()
