Given a NSManagedObject like below:
public class Folder: NSManagedObject, Identifiable {
	@NSManaged public var name: String
	@NSManaged public var position: Int16
	@NSManaged public var parentFolder: Folder?
	@NSManaged public var folders: Set<Folder>
}
I'd like to use the new OutlineGroup to build an outline view of the folder structure using a FetchRequest.
struct FolderView {
@FetchRequest(entity: Folder.entity(),
							sortDescriptors: [NSSortDescriptor(keyPath: \Folder.position, ascending: true)]) var folders: FetchResults<Folder>
	var body: some View {
		OutlineGroup(folders, children: \.folders) { folder in
			Label(folder.name, systemImage: "folder.fill")
	}
But this doesn't compile, with the following error:
Key path value type 'Set<Folder>' cannot be converted to contextual type 'FetchedResults<Folder>?' Any idea?
As a bonus, the children should also be ordered by the position (because it's a Set, it's unordered)…
