You can remove/delete user like this:

Note: Some security-sensitive actions—such as deleting an account, setting a primary email address, and changing a password—require that the user has recently signed in.

 let credential: AuthCredential

            user.reauthenticate(with:credential) { error in
                if let error = error {
                    // An error happened.
                    showAlertWithErrorMessage(message: error.localizedDescription)
                } else {
                    // User re-authenticated.
                    user.delete { error in
                        if let error = error {
                            // An error happened.
                            showAlertWithErrorMessage(message: error.localizedDescription)
                        } else {
                            // Account deleted.
                            Database.database().reference(fromURL: kFirebaseLink).child(kUser).child(userID).removeValue()

                            try!  Auth.auth().signOut()
                            self.navigationController?.popToRootViewController(animated: true)
                        }
                    }

                }
            }
        }else{
            showAlertWithErrorMessage(message: "Try again later")
        }

This way achieve delete user functionality in my ios app.(remove user from firebase authentication and database both side)

100% working and tested
