I have a little question that I do not dare to ask because it is so trivial. can SwiftData actually handle compound keys? like other databases have been doing for over 30 years? i would be very disappointed if this was still not possible....

Hello Guys, I have a simple code in SwiftUI     Menu { Text("Item") } label: { Text("Menu") } But it's produce an Error like this: "[UILog] Called -[UIContextMenuInteraction updateVisibleMenuWithBlock:] while no context menu is visible. This won't do anything." But this is no warning, in fact, there happens nothing. Has anybody an idea, how to get rid this error message? Thanks in Advance DWD

Hello,there it's easy to convert a UIImage to an Image. But how I can convert an Image? to an Binding of UIImage?Thank youDWD

Hello Everyone,A short note first, unfortunately the following code is working, I am posting in anyway to show how the whole thing is built up. To make it executable, it still needs a CoreData table named "Person" with three columns (Id = UID, firstname = string, lastname = string).The problem would be here, in the structure "PersonView", not when calling but when changing the detail view.Here the changed record is simply removed from the view instead of displaying it. As long as there is no update, there is no problem.I suppose that the problem in the original is that the @FetchRequest in PersonView is not refreshed. It could also be that the @FetchRequest uses a different managedObjectContext than the one saved.Here are three questions:a) How can you specify an @FetchRequest (see PersonView) which managedObjectContext it should use?b) how could you restart the @FetchRequest when returning a detail view in PersonViewc) how could the functions load() and save() in Object DPerson be made nicer so that it doesn't look so bumpy.As I said, the example unfortunately works, so please see it only as an illustration.Many thanks in advance.import SwiftUI import CoreData class DPerson: ObservableObject { @Published var vorname: String = "" @Published var nachname: String = "" var id: UUID? var ctx: NSManagedObjectContext? func setContext(ctx: NSManagedObjectContext){ self.ctx = ctx } func load(id: UUID){ let request: NSFetchRequest<Person> = Person.fetchRequest() request.predicate = NSPredicate(format: "id = %@", id.description) if let m = try? ctx?.fetch(request), m.count == 1 { self.id = m[0].id self.vorname = m[0].vorname ??
