I have a CoreData File that contains two entities. I'm experiencing an issue when trying to fetch items from these entities. Fetching items from the first entity works fine, but I'm encountering problems with the second entity.
In one of my views, I fetch and display the first entity in a list successfully. However, when I try to show the second entity in a different view using a @FetchRequest, the view doesn't refresh and display the data. I have to restart the app for all the data and items to appear.
Interestingly, when I have two or more items from the second entity fetched and I delete one of them, the view refreshes properly. But if I try to delete the last item, the view doesn't refresh.
Does anyone know how I can resolve this issue?
First Fetch-Request: @FetchRequest(sortDescriptors: [ NSSortDescriptor(keyPath: \FirstEntity.name, ascending: true)], predicate: NSPredicate(format: "finished == %d AND consumed == %d", true, false) ) var firstResult: FetchedResults<FirstEntity>
Second Fetch-Request: @FetchRequest(sortDescriptors: [ NSSortDescriptor(keyPath: \SecondEntity.created, ascending: true)]) var secondResult: FetchedResults<SecondEntity>
My View-Code:
@Environment(\.managedObjectContext) var managedObjectConetext
@ObservedObject var item: SecondEntity
var body: some View {
ZStack (alignment: Alignment(horizontal: .leading, vertical: .top)) {
HStack {
if let data = item.image {
