Error reflection with SwiftProtobuf

[KennethLaw]

struct UserLoginRes {
  // 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.

  var code: Int32 {
    get {return _storage._code}
    set {_uniqueStorage()._code = newValue}
  }

  var message: String {
    get {return _storage._message}
    set {_uniqueStorage()._message = newValue}
  }

  var data: UserInfo {
    get {return _storage._data ?? UserInfo()}
    set {_uniqueStorage()._data = newValue}
  }
  /// Returns true if `data` has been explicitly set.
  var hasData: Bool {return _storage._data != nil}
  /// Clears the value of `data`. Subsequent reads from it will return its default value.
  mutating func clearData() {_uniqueStorage()._data = nil}

  var unknownFields = SwiftProtobuf.UnknownStorage()

  init() {}

  fileprivate var _storage = _StorageClass.defaultInstance
}

extension UserLoginRes: SwiftProtobuf.Message, SwiftProtobuf._MessageImplementationBase, SwiftProtobuf._ProtoNameProviding {
  static let protoMessageName: String = _protobuf_package + ".UserLoginRes"
  static let _protobuf_nameMap: SwiftProtobuf._NameMap = [
    1: .same(proto: "code"),
    2: .same(proto: "message"),
    3: .same(proto: "data"),
  ]

  fileprivate class _StorageClass {
    var _code: Int32 = 0
    var _message: String = String()
    var _data: UserInfo? = nil

    static let defaultInstance = _StorageClass()

    private init() {}

    init(copying source: _StorageClass) {
      _code = source._code
      _message = source._message
      _data = source._data
    }
  }

  fileprivate mutating func _uniqueStorage() -> _StorageClass {
    if !isKnownUniquelyReferenced(&_storage) {
      _storage = _StorageClass(copying: _storage)
    }
    return _storage
  }
....

Usage: let realResp = try typeInfo(of: UserLoginRes.self)

Debug:

Q: Can not find property "code" and "message"? Only "unknownFields" and "_storage"?

This is actually the expected output. It can only get metadata for stored properties.
