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 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 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'm trying to follow the Date Planner tutorial and the symbol picker went really weird. I changed sth, and the whole app stoped working I changed it back, it still wont work. SymbolPicker code: struct PickerView: View {     @State var item: TodoItem     @State private var showingPopover: Bool = false     var columns = Array(repeating: GridItem(.flexible()), count: 6)     var body: some View {         LazyVGrid(columns: columns){             ForEach(SymbolOptions.symbolNames, id: \.self){ symbol in                 Button {                     item.symbol = symbol                 } label: {                     Image(systemName: symbol).foregroundColor(item.color)                 }             }         }     } }

How can i write an About page in swiftUI about my app? I cant find any documentation on it

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

I'm trying to add a quick look preview extension to my app. But I can't find any reference on this On a earlier thread (https://developer.apple.com/forums/thread/704155) everyone seems to misunderstand my question. I MEAN THE QUICK LOOK YOU CAN TOGGLE IN FINDER THAT WILL SHOW YOU A PREVIEW OF A DOCUEMNT I don't want to add the tag QuickLook because that's not I want to do.

How can I make it work? jsonString = """ ["foo", "bar"] """ let decoder = JSONDecoder var whatIWant = decoder.decode(Array<String>.self, jsonString) for i in whatIWant { print(i) } EDIT: Minor syntax mistake ignore this thread sorry everyone

2022-06-09 08:51:30.793789+0800 MyAppName[4651:447798] [aqme]        MEMixerChannel.cpp:1629  client <AudioQueueObject@0x7fc09a04f400; [0]; play> got error 2003332927 while sending format information I use .mp3

I know this is really easy I want to get the absolute path for the current app And I can achieve using String(reflecting: Bundle.main.bundleURL) But what outputs isn't like /User/xxx/..... but file:///User/xx/... so what can I do to get a absolute path in /xxx/xxx/xxx format? thanks

I know how to use Virtualization now But I don't know how to write interface in AppKit So I should find a way to embed a NSView(the VM's UI) in a SwiftUI View However I couldn't find any reference on how except NSViewRepresentable which, of course, will not work I know there must be a easy way to do this But I'm just can't find it... any help is appreciated

I'm trying out Swift Charts and I'm pretty messed up After I deleted all of my items, I couldn't add items anymore import SwiftUI extension Array where Element == ChartsData {     mutating func delete(_ item: ChartsData) {         self.removeAll {             $0 == item         }     } } struct ContentView: View {     var ofType: ChartsType     @State var data: [ChartsData] = []     var body: some View {         List {             VStack {                 HStack {                     Spacer() // MARK - add button                     Button {                         data.append(ChartsData(item: "item"))                     } label: {                         Image(systemName: "plus").imageScale(.large)                     }.buttonStyle(.plain).padding()                 }                                  List {                     ForEach(data) { datum in                         TableRow(data: datum).swipeActions {                             Button(role: .destructive) {                                 data.delete(datum)                             } label: {                                 Label("Delete", systemImage: "trash")                             }                         }                     }                 }                 NavigationLink{                     ChartsView(ofType: .BarChart, data: data)                 } label: {                     Text("Generate").font(.largeTitle).foregroundStyle(.linearGradient(colors: [.orange, .yellow, .blue, .purple], startPoint: .topTrailing, endPoint: .bottomLeading))                 }.padding()             }         }     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView(ofType: .BarChart, data: [             ChartsData(item: "testItem1", value: 10),             ChartsData(item: "testItem2", value: 20)         ])     } }

OK after I'm done with my last issue I came across some weird UI layout this is really a serious issue because afterward it looks like this😂 why? I've never met this kind of issue before in my same code before upgrading to Ventura code: List { ...                 Section {                     ForEach(data) { datum in                         TableRow(data: datum)                             .swipeActions {                             Button(role: .destructive) {                                 data.delete(datum)                             } label: {                                 Label("Delete", systemImage: "trash")                             }                         }                     }                 } ... }
