Jake on CloudKit and Groups

Jake Savin: Square Pegs and Round Holes:

It’s possible separately via a web portal (not programmatically as far as I know), to configure a subset of data to be editable only by specific people, but the idea is more about providing a way for the maintainers of some data resources to update that data, than it is about providing a mechanism for users to create ad-hoc groups among themselves. (i.e. dynamic configuration data that’s loaded by the app at launch.)

While this is a super useful feature, the value of which hasn’t really been called out much by the iOS dev community, it is not what Marco Tabini described. (I can see how the misunderstanding arose though.)
