Looks like SwiftUI + CoreData (+ FetchRequest) have a bug: if I pass NSManagedObjectContext into a child view and create a new CoreData object in such child view, with the context injected via constructor, I get an endless recursive rebuild of views.

Run the build as usual and see the debug area. If you comment out the ForEach() in the ContentView, the recursion will disappear.
