Hi, I am using a NSOutlineView with a simple @FetchRequest containing content: and detail: sections. e.g. NavigationSplitView { List(tags, selection: $selectedTag) { tag in NavigationLink(value: tag) { Text(tag.name ?? "") } } } content: { if let selectedTag { let fetchRequest = FetchRequest(fetchRequest: Location.sortedFetchRequest(tag: selectedTag)) AGLocationListView(locations: fetchRequest) } else { Text("Select a Tag") } } detail: { if let selectedTag { AGMapView(viewModel: AGMapViewModel(tag: selectedTag)) } } } I am inserting a new record using the viewContext on the main thread. in the case when there are no records in the Tag entity I sometimes see the following error: 2023-05-11 22:49:36.388105+1200 Taggy[24576:1000186] [General] NSOutlineView error inserting child indexes <_NSConstantIndexSet: 0x7ff857d84860>[number of indexes: 1 (in 1 ranges), indexes: (1)] in parent 0x0 (which has 0 children). Then a large stack trace topmost line being: 2 AppKit 0x00007ff818343b6b -[NSOutlineView _validateParentRowEntry:reason:indexes:] + 0 then see: NSHostingView is being laid out reentrantly while rendering its SwiftUI content. This is not supported and the current layout pass will be skipped. 2023-05-11 22:49:38.376608+1200 Taggy[24576:1000186] [SwiftUI] Publishing changes from within view updates is not allowed, this will cause undefined behavior. Not sure what I am doing wrong here or if this is an issue with SwiftUI on the Mac with the Split View? Thanks Ants

Hi, I am trying to generate an image of a specific size (from a map in this case using MKMapSnapshotter). The image generation code is fine. my view is like this @ObservedObject public var viewModel: ViewModel var body: some View { GeometryReader { geometry in Image(uiImage: viewModel.mapImage) .frame(width: geometry.size.width, height: 50) .cornerRadius(5) .task(priority: .userInitiated) { await viewModel.loadImage(size: CGSize(width: geometry.size.width, height: 50) } } } } This is used from another view that uses a @SectionedFetchRequest inside a nav stack list and foreach. the mapImage property of the view model is @Published. This sort of works and the first few rows show an image. However, as you scroll some views do not get the image update. I added some logging and I can see that the view model is getting released so the loadImage() method does not get called. The weird thing is if I drag a row that has no image, it is immediately generated. Any ideas as to how I could get this to work for all rows? Thants
