UICloudSharingContainer equivalent on macOS (i.e. SwiftUI)?

If UICloudSharingContainer means UICloudSharingController here, its counterpart on macOS is NSSharingServicePicker. If you are making a SwiftUI app, consider using ShareLink to create a new share (CKShare), and using UIActivityViewController / NSSharingServicePicker to manage a share.

The following sample should give you a starting point:

• Sharing Core Data objects between iCloud users

Oh thank you, @DTS Engineer, that's helpful. Yes, I meant UICloudSharingController. I had completely failed to remember ShareLink, not realizing it works for this case.

Ideally, I'd be able to use SwiftData for the bulk of my local objects, but afaik there’s no direct support for CKShare in SwiftData.

Can you tell me if I have to create the Core Data stack from scratch, or can I insert the necessary bits (e.g. all the descriptions and options for shared zones, etc.) into the stack created by the Swift Data APIs?

Regarding SwiftData + CloudKit share, I mentioned my opinion in the following post, which I think answers your question as well:

• Does SwiftData currently supports data sharing among multiple users through iCloud?

Thank you. It sounds like the best approach is to start with a standard/traditional Core Data stack and "migrate" to Swift Data from there.
