Question

使用Google protobufs + iOS和Swift。使用官方插件将protobuf文件编译为Swift，我得到了很好的结果，但是type_id从Swift代码中省略了，这对于我的代码正常工作是必不可少的。我相信它叫做“消息描述符”。例如-protobuf文件包含：

message AuthRequest {
  option (type_id) = 1001;
  // Commissioning credential
  string password = 1;
}

Swift中的结果代码：

struct AuthRequest {
  // SwiftProtobuf.Message conformance is added in an extension below. See the
  // `Message` and `Message+*Additions` files in the SwiftProtobuf library for
  // methods supported on all messages.

  /// Commissioning credential
  var password: String = String()

  var unknownFields = SwiftProtobuf.UnknownStorage()

  init() {}
}

...

extension AuthRequest: SwiftProtobuf.Message, SwiftProtobuf._MessageImplementationBase, SwiftProtobuf._ProtoNameProviding {
  static let protoMessageName: String = _protobuf_package + ".AuthRequest"
  static let _protobuf_nameMap: SwiftProtobuf._NameMap = [
    1: .same(proto: "password"),
  ]

  mutating func decodeMessage<D: SwiftProtobuf.Decoder>(decoder: inout D) throws {
    while let fieldNumber = try decoder.nextFieldNumber() {
      switch fieldNumber {
      case 1: try decoder.decodeSingularStringField(value: &self.password)
      default: break
      }
    }
  }

  func traverse<V: SwiftProtobuf.Visitor>(visitor: inout V) throws {
    if !self.password.isEmpty {
      try visitor.visitSingularStringField(value: self.password, fieldNumber: 1)
    }
    try unknownFields.traverse(visitor: &visitor)
  }

  func _protobuf_generated_isEqualTo(other: AuthRequest) -> Bool {
    if self.password != other.password {return false}
    if unknownFields != other.unknownFields {return false}
    return true
  }
}

是否需要某种命令行开关/参数/其他操作才能访问Swift代码中的type_id值？

谢谢！
