Just to note, this also doesn't work in the sample app Synchronizing a Local Store to the Cloud. I can share a post and make changes to that post that the other user will see. But I can't share attachments to that post, because those NSManagedObjects aren't being shared.

Just to note: This also doesn't work in the sample app Synchronizing a Local Store to the Cloud. In the sample app, I can share a post and make changes to that post that will be synced. But if I add attatchements, those aren't synced. Presumably because those NSManagedObjects aren't part of the CKShare.

This is our workaround to get the old behavior back: GeometryReader { proxy in ZStack { Color.green ZStack { Color.yellow Text("Hi") } .aspectRatio(1, contentMode: .fill) .border(.red) } .frame(width: proxy.size.width, height: proxy.size.height) }
