Firebase delete account along with Database and Storage on iOS

问题

I am trying to implement a function to delete current user's account on iOS. Account deletion works properly but the problem is that I cannot delete the account's data from Database and Storage when deleting an account.

"currentUser.delete" deletes the account but I think there is no authentication to delete its data from Database and Storage. Permission denied message shows up in the log. After running this function, I get to see the account is gone in Firebase Console Authentication page but data from Database and Storage persists.

Is this the correct way to delete an account?

I tried to delete data from Database and Storage before deleting the account. However, Firebase asks for re-authentication if session is more than 5 minutes old. Re-login shows empty data to the user before performing account deletion again so this is misleading and very confusing.

Please let me know how to remove data when deleting an account.

private func deleteAccount() {
  guard let currentUser = Auth.auth().currentUser else {
    return print("user not logged in")
  }

  currentUser.delete { error in
    if error == nil {
      // 1. Delete currentUser's data from Database. Permission denied
      // 2. Delete currentUser's data from Storage. Permission denied
      // present login screen (welcome page)
      self.presentLoginScreen()
    } else {
      guard let errorCode = AuthErrorCode(rawValue: error!._code) else { return }

      if errorCode == AuthErrorCode.requiresRecentLogin {
        self.showMessage("Please re-authenticate to delete your account.", type: .error)

        do {
          try Auth.auth().signOut()
          self.presentLoginScreen()
        } catch {
          print("There was a problem logging out")
        }
      }
    }
  }
}
