I think we can use modelContainer.mainContext.autosaveEnabled = ... for autosave. However it is not tested if this actually has an effect, only if it complies, as Previews currently crash for me.

Hello, im still having this issue at Xcode beta 5, and none of the above workarounds does work either.
My #Preview Code:
#Preview {
MainActor.assumeIsolated {
let modelContainer: ModelContainer = ModelContainer.preview()
return TaskListView()
.modelContainer(modelContainer)
}
}
My ModelContainer.preview() Code:
#if DEBUG
@MainActor
extension ModelContainer {
static func preview() -> ModelContainer {
do {
let modelContainer = try ModelContainer(for: [TaskListModel.self], ModelConfiguration(inMemory: true))
for element in [TaskListModel].preview() {
modelContainer.mainContext.insert(element)
}
return modelContainer
} catch let error {
fatalError("[ModelContainer] static preview(taskLists:): \(error.localizedDescription)")
}
}
}
#endif
