I also tried changing the method of deletion to the following. This tries to delete entity Object that has a to-many relationship children: [Child]. guard let id = object.id else { return } do { try container.mainContext.delete(model: Object.self, where: #Predicate { object in object.id == id }) } catch { print(error) } This does not crash the app, but fails to delete the entity with the following console output: Error Domain=NSCocoaErrorDomain Code=134060 "A Core Data error occurred." UserInfo={Reason=Entity named:Object not found for relationship named:children, MissingEntity=Object. (<NSEntityDescription: 0x6000035100b0>) ... I'm not sure what this means, perhaps someone more clever will find it useful. @DTS Engineer

I'm having the same issue. Things I tried (none of them worked): Remove .cascade delete rule Remove all children-type entities before removing the parent-type entity .swipeActions as well as .onDelete

I'm having the same problem, specifically when attempting to delete a model instance. It seems to be an instance that existed prior to a change to the model properties. Instances created after the change to model properties are deleted ok, but this one has become "sticky".

Same issue here. Have you been able to resolve this?

I'm having the same problem

Building on zulfishah's solution, just executing the button closure in an async context fixes the issue for me. Button(role: .destructive) { Task { deleteObject() } } label: { Label("Delete", systemImage: "trash.fill") }

We also have this issue. Feedback submitted some time ago under FB13201571. Editing works, as long as NavigationStack is not used. This works. struct ListSelectionTest: View { @State var selection: Set<String> = [] let strings = ["One", "Two", "Three"] var body: some View { VStack { EditButton() List(selection: $selection) { ForEach(strings, id: \.self) { string in Text(string).tag(string) } } } } } The problem appears when the List is wrapped in NavigationStack. This only works when the EditButton is tapped TWICE. struct ListSelectionTest: View { @State var selection: Set<String> = [] let strings = ["One", "Two", "Three"] var body: some View { NavigationStack { VStack { EditButton() List(selection: $selection) { ForEach(strings, id: \.self) { string in Text(string).tag(string) } } } } } } Replacing EditButton with a custom Button produces a different visual error. Editing is set correctly, but the multi-selection indicators quickly appear and then disappear again. struct ListSelectionTest: View { @Environment(\.editMode) private var editMode @State var selection: Set<String> = [] let strings = ["One", "Two", "Three"] var body: some View { NavigationStack { VStack { Button((editMode?.wrappedValue.isEditing ?? false) ? "Done" : "Edit") { editMode?.wrappedValue = (editMode?.wrappedValue.isEditing ?? false) ? .inactive : .active } List(selection: $selection) { ForEach(strings, id: \.self) { string in Text(string).tag(string) } } } } } } In short, we suspect there is a SwiftUI bug related to triggering List editing when the list is in NavigationStack.

Same problem here. I'm struggling with extracting NavigationPath() into a separate class using @Observable. When this class is marked as @Observable, typing NavigationStack(path: viewModel.path) {...} results in error: Cannot convert value of type 'NavigationPath' to expected argument type 'Binding<NavigationPath>' Variations like $viewModel.path or viewModel.$path do not work either. The only "working" solution is: var body: some View { @Bindable var bindable = viewModel NavigationStack(path: $bindable.path) {...} } But this is very hacky.

I still have this issue. When working with Map() and MapAnnotation(), I get swamped by console prints and purple warnings. Apple please provide a fix or advice!

I struggled with this a year ago. In the end I restructured my model so it works without unique constraints. For example, you may have a many-to-many relationship between entities Color and Animal (an animal may have multiple colours, and vice-versa: a specific colour may be found on various animals). Without unique constraints, you can fetch animals by colour like this:     if colorFilter != .noValue {       // any animal where color in colors relationship contains value       predicates.append(NSPredicate(format: "ANY colors.color == %@", colorFilter.rawValue))     }

I tried to train the model programmatically in a Swift Playground. This process also failed and returned the following error (I have no idea what it means). Training on a smaller subset of the dataset succeeds. remoteProcessWasInterrupted Error: ["ThreadID": 1278902, "ThreadCrashed": 1, "StackFrameDictionaries": <__NSArrayM 0x600001fe0570>( {     StackFrameModule = vImage;     StackFramePC = 7223916652;     StackFrameSymbolName = "__ERROR_Buffer_Write__Too_Small_For_Arguments_To_vImage__CheckBacktrace"; }, {     StackFrameModule = vImage;     StackFramePC = 7223916524;     StackFrameSymbolName = "_vImageDebug_CheckDestBuffer"; }, {     StackFrameModule = vImage;     StackFramePC = 7223913756;     StackFrameSymbolName = "_vImageConvert_AnyToAny"; }, ... // more fields follow ) ]

This is now confirmed by Apple as a known bug with high priority. A detailed, up-to-date post is kept at SO: https://stackoverflow.com/questions/73888519/uicloudsharingcontroller-does-not-work-for-core-data-with-cloudkit
