I am trying to add CloudKit sharing to my app using the new iOS 15 share method  https://developer.apple.com/documentation/coredata/nspersistentcloudkitcontainer/3746834-sharemanagedobjects In the app there are 3 core data entities (Folder, Item, Comment) with the following relationships: A Folder contains many Items An Item has many Comments I want to use CloudKit to share just the Item entity, not any of its relationships. Is this possible to do with the share(_:to:completion:) method? Currently, when I pass an Item to the share method it also includes the Folder and Comments in the CKShare. How do I prevent this?

I updated to beta 4 and started getting this error when I try to apply the .sidebar appearance to the primary view of a UISplitViewController. To replicate this issue I modified the 'Modern Collection Views' sample code to use a UISplitViewController and set the primary view to be the sample code. As soon as the primary view becomes visible, the app crashes with this error 2020-08-05 08:34:36.582560-0500 Modern Collection Views[38363:6217715] * Assertion failure in -[UIListContentConfiguration
