Silly me... func fileWrapper(configuration: WriteConfiguration) throws -> FileWrapper { let fileContent = try JSONEncoder().encode(self.document) return FileWrapper(regularFileWithContents: fileContent) }

import SwiftUI struct ProviderCalendarView: View { @StateObject var viewModel = YearViewModel() @State private var selectedYear = 3 var body: some View { VStack { HStack { Picker(selection: $selectedYear) { ForEach(viewModel.years, id: \.self) { year in Text("\(year)") } } label: { } } } } } class YearViewModel: ObservableObject { @Published var years: [Int] = [] init() { createYears() } func createYears() { let now = Date() for i in 0..<4 { years.append(2023 + i) } } } I don't use Range to create an array in this case. Yet, I still get the same compiler guy.

The following works. Picker(selection: $selectedYear) { ForEach(viewModel.years.indices, id: \.self) { Text("\(viewModel.years[$0])") } } label: { }

I think another approach is use of an ObservableObject class with onReceive(_:perform:) .

You aren't really telling what you are trying to do. No screenshot? Why are you applying the height value you get from the gray rectangle to the other?

What is screenCoord? Where does it come from?

I am able to use the contextMenu guy to navigate to another View. Do I miss something? import SwiftUI struct ContentView: View { var body: some View { NavigationStack { FirstView() } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } struct FirstView: View { @State var goToSecond = false var body: some View { VStack { Text("FirstView") .contextMenu { Button("Go to Second View") { goToSecond.toggle() } } } .navigationDestination(isPresented: $goToSecond) { SecondView() } } } struct SecondView: View { var body: some View { VStack { Text("SecondView") } } }

You aren't using the selectedValue variable in ContentView. So nobody knows how the selectedValue variable in MyPicker is supposed to affect ContentView. If the selectedValue variable in MyPicker is supposed to affect ContentView, then make it Binding.

It's not working because parent.color in Coordinator is not returned to UIColorPickerViewController. Use a Binding variable in Coordinator to pass the selected color back to UIColorPickerViewController. Besides, why do you use UIColorPickerViewController to access UIColorPickerViewController? SwiftUI has a guy named ColorPicker.

I've changed class FrameModel: NSObject, NSCoding { } into class FrameModel: NSObject, NSSecureCoding { class var supportsSecureCoding: Bool { true } } Muchos thankos, eskimo.

I get a lot of hits by running a search for 'SwiftUI battery level.'

I don't have a definite answer, but I don't see why you cannnot. I have tried reading a SwiftUI file that comes with Swift Charts, using UIHostingController. That's been successful. So try that if you like.

You can simply use HStack to separate the name text and its corresponding image. import SwiftUI struct ContentView: View { var body: some View { TabView{ FirstView() .tabItem { HStack { Text("Save") .fixedSize() Image(systemName: "lock.fill") } } SecondView() .tabItem { HStack { Text("Things") .fixedSize() Image(systemName: "message.fill") } } } } } struct FirstView: View { var body: some View { Text("First") } } struct SecondView: View { var body: some View { Text("Second") } }

At which line do you write a file to the triggersDirectory folder? 'triggersDirectory' appears three times, but I don't see that. You do write a file to the reflectionsURL folder.

As long as your application already has a functional ability for those who use it with free of charge, I don't see a problem.
