Nested Composite Attribute values are not saved in the database

According the WWDC23 presentation “What’s new in Core Data”, “Composite attributes may be nested within each other”.

However, in the current macOS and iOS beta builds, only single level composite attributes (without nested composite attributes) are persisted in the SQLite database.

Is this still work in progress?

See example project in FB12552092.

This seems to be fixed in the current release versions of iOS and macOS
