Since "The "out-of-the-box" implementation of CoreData / CloudKit sync does not, and will not, store any records in the Public database" how does one go about storing records in the public database (when I look using the CloudKit dashboard, there are only private records, nothing in public)? I know about setting databaseScope = .public in NSPersistentCloudKitContainerOptions, & about assigning managed objects to the appropriate scope (needed because my app has more than one). What am I missing?
