I'd like to make the items in my sidebar rearrangeable, like Finder, but when I apply the SidebarListStyle it breaks and causes a crash (tested on Big Sur). By removing the style, reordering works as expected. Is there another modifier I should be using? Thanks!
@main
struct MyApp: App {
	var body: some Scene {
		WindowGroup {
			ContentView()
		}
		}
	}
struct ContentView: View {
	@State var strings: [String] = ["A", "B", "C"]
	@State var selection: String?
	var body: some View {
		NavigationView {
			List(selection: $selection) {
				ForEach(strings, id: \.self) { string in
					Text(string)
				}
				.onMove { (indexes, dest) in
					withAnimation {
						self.strings.move(fromOffsets: indexes, toOffset: dest)
					}
				}
			}
			.listStyle(SidebarListStyle())
			VStack {
				Spacer()
				Text(selection ?? "<none>")
					.frame(idealWidth: 100, maxWidth: .infinity, alignment: .center)
				Spacer()
			}
		}
	}
}
I opened Feedback FB7520923 to track the issue too.

Adopt the new look of macOS covered how to create a full screen sidebar in AppKit, but I'm not able to figure out how to accomplish this with SwiftUI. Any ideas as to what I'm missing?
@main
struct MyApp: App {
var body: some Scene {
		WindowGroup {
ContentView()
		}
}
}
struct ContentView: View {
@State var strings: [String] = ["A", "B", "C"]
@State var selection: String?
var body: some View {
	 HSplitView {
List(selection: $selection) {
ForEach(strings, id: \.self) { string in
Text(string)
	}
	 }
			.listStyle(SidebarListStyle())
	 VStack {
Spacer()
Text(selection ?? "<none>")
.frame(idealWidth: 100, maxWidth: .infinity, alignment: .center)
		 Spacer()
			}
}
}
}
I already filed FB7776520 in case it's not possible, but I'm assuming I'm missing something since it's a marquee feature. Thanks!
Update: If I replace HSplitView with NavigationView it works as expected. 🤦♂️
