I guess I shouldn't do it after reading https://developer.apple.com/forums/thread/78244 .

I've made some change the App View as follows. import SwiftUI @main struct LocaleSwitchCrazyMamaApp: App { @StateObject var lanSetting = LanguageSetting() var body: some Scene { WindowGroup { ContentView() .environmentObject(lanSetting) .environment(\.locale, lanSetting.locale) } } } The outcome doesn't change, though.

The deployment target is iOS 16.

Personally, I think it's a SwiftUI bug. I have a similar problem with the ImageRenderer class and get the same symbol. I've filed a feedback report. It's been 5 or 6 weeks. When I filed a bug report 9 or 10 years ago regarding Core Graphics, I had to wait for 3 months. If possible, you may write code in Cocoa and use it as NSViewControllerRepresentable or NSViewRepresentable.

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.

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.

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") } }

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.

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

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

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.

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.

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") } } }

What is screenCoord? Where does it come from?

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?
