first line of code: struct UserTip: Tip {

Missed the first line of code: static let hoverEvent: Event = Event(id: "hoverEvent") /// Parameters-Rules @Parameter static var isHovering: Bool = false static var tipCountKey = "UserTipCount" var title: Text var message: Text? var image: Image? var tipShownLimit: Int @ObservedObject var buttonState: ButtonState var rules: [Rule] { [ #Rule(Self.$isHovering) { $0 == true }, #Rule(Self.hoverEvent) { $0.donations.count < 10 } ] } }

I was able to fix this. Uninstalled Xcode. Rebooted. Reinstalled Xcode. This time the dialog came up for installing additional pieces. Xcode now runs fine

The error is Command RealityAssetsCompile failed with a nonzero exit code

I resolved this issue. I had to specify in the browser to encode as multipart/form-data and then on the server: case http.MethodPost: contentType := request.Header.Get("Content-Type") if strings.HasPrefix(contentType, "multipart/form-data") { p.DataBodyMap = make(url.Values, 0) request.ParseMultipartForm(1000) for key, value := range request.MultipartForm.Value { p.DataBodyMap[key] = value } photoFile, header, err := request.FormFile("photoBytesString") if err == nil { log.Println(header, err) photoContentType := header.Header["Content-Type"][0] log.Println(photoContentType) photoBytes, _ := ioutil.ReadAll(photoFile) log.Println("len(photoBytes): ", len(photoBytes)) encodedImage64 := base64.StdEncoding.EncodeToString(photoBytes) encodedImage64WithPrefix := "data:" + photoContentType + ";base64," + encodedImage64 p.DataBodyMap["photoBytesString"] = []string{encodedImage64WithPrefix} }
