I'm doing a app that needs a toolbar but it wont come out: ContentView() .toolbar {             ToolbarItem {                 Button {                     data.data.append(TodoItem())                 } label: {                     Image(systemName: "plus")                 }             }         }

I know there should be a easy solution to this mess but I JUST CAN'T FIND IT AHHHHHHHHHH     cd ...... error: Build input file cannot be found: '/Users/xxx/Library/Developer/Xcode/DerivedData/ColorLibrary-hakdntgphjogwuawcvuxomfrjzex/Build/Products/Debug-iphonesimulator/ColorKit iOS.app/ColorKit iOS' (in target 'ColorKit iOS' from project 'ColorLibrary')

I want to include a button that could export some data but I'm stuck: I want a NSSavePanel open up and when I choose the pass and click save the JSON file will appear but it didn't. code: Button {     let export = exportToJSON(toExported(data.data))     let openPanel = NSSavePanel()     openPanel.message = "Choose the exported path:"     openPanel.begin { response in         if response == .OK {             print("\(openPanel.url!)")             url = openPanel.url!             let fileManager = FileManager()             let success = fileManager.createFile(atPath: "\(url)", contents: export)             debugPrint(success)         }     } } label: {     Image(systemName: "square.and.arrow.down") }.padding().buttonStyle(.plain) console: file:///Users/xxx/Documents/Untitled false

Still about appstorage Can a store a @StateObject in @AppStorage? I can't do this: @AppStorage("Data") // No exact matches in call to initializer  @StateObject private var Data = TodoData()

I'm using SwiftUI on Mac Catalyst: @main struct TodoApp: App {     @StateObject private var eventData = TodoData()     var body: some Scene {         WindowGroup {             ContentView().environmentObject(eventData)         }         #if os(macOS)         Settings{             TodoSettings()         }         #endif     } }

I have a app that needs to have a "choose file" function and I used a button hooked up to a function using NSOpenPanel to do that. But after I tried to add a drag&drop action, it wont work anymore. I revert all my files to the version when the NSOpenPanel work, but it's still the same. I also tried to restart my computer, all the same. Here's my function: private func selectFile() {         let openPanel = NSOpenPanel()         openPanel.canChooseDirectories = false         openPanel.allowsMultipleSelection = false         openPanel.begin { response in             if response == .OK {                 self.url = openPanel.url             }         }     } should I file a bug? should I reinstall xcode?

I'm trying to make an app that'll suggest a color based on a keyword the user inputs. I store prediction from the model to a [String: Double] array and then compute the output color. However, I'm stuck on two strange errors. Here's my code: extension Array where Element == [String: Double]{ func average() -> RGBList{ var returnValue = (r: 0, g: 0, b: 0) var r = 0 var g = 0 var b = 0 for key in self{ r = Int(key[0].split(",")[0]) * key[1] ... } ... } }

I have a big problem with an AI app. It's supposed to give me a color according to the text entered into a TextField. But every time it gives me the same output. I'm new in developing, and I know it must be a tiny bug but I just couldn't find out why. Should I just ... paste all of my code here? I can't upload a .zip :(

Hi! I'm new to Apple developing. Could anyone please tell me how to configure a quick look for my document? Also, how to print my document? Thanks🙏

I'm tired of opening up safari to open developer.apple.com so I'm trying to embed the website into an app, but sth is definitely wrong. It's been loading for ten mins and is still white. here's the code import SwiftUI import WebKit import UIKit struct WebViewPage : UIViewRepresentable { func makeUIView(context: Context) -> WKWebView { return WKWebView() } func updateUIView(_ uiView: WKWebView, context: Context) { let req = URLRequest(url: URL(string:"developer.apple.com")!) uiView.load(req) } } #if DEBUG struct WebViewPage_Previews : PreviewProvider { static var previews: some View { WebViewPage() } } #endif app delegate: import SwiftUI @main struct Developer_WebpageApp: App { var body: some Scene { WindowGroup { WebViewPage() } } }
