swift - 如何处理 Firebase Auth 错误？/Swift/Firebase

Question

嘿伙计们，有人能告诉我如何处理这个吗？我尝试了很多，但如果我纠正一个错误，另一个错误就会出现......提前致谢

Auth.auth().createUser(withEmail: eMailTextField.text!, password: passwordTextField.text!) { (data, error) in
            if error != nil {
                if let errCode = error as NSError? {
                    
                    guard let errorCode = AuthErrorCode(rawValue: error) else {
                                    print("there was an error logging in but it could not be matched with a firebase code")
                                    return

                                }
                    
                    switch errorCode {
                        case .FIRAuthErrorCodeNetworkError:
                            print("No Internet Connection")
                        case .ErrorCodeEmailAlreadyInUse:
                            print("in use")
                        default:
                            print("Create User Error: \(error!)")
                    }
                    
            }
                
            } else {
                print("all good... continue")
                        }

您可以连接到 NSError，然后根据 error.code 创建 AuthErrorCode:

Auth.auth().createUser(withEmail: "MyEmail", password: "MyPassword") { authResult, error in
            if error != nil, let error = error as NSError? {
                if let errorCode = AuthErrorCode(rawValue: error.code) {
                    switch errorCode {
                    case .invalidEmail:
                        break
                    case .emailAlreadyInUse:
                        break
                    default:
                        break
                    }
                }
            } else {
                //no error
            }
        }

请注意，我只列出了几个 errorCode 可能性 - 它们的列表非常广泛。
