I ended up writing my own object graph framework. Interestingly, many parts of
the implementation fell naturally into the same mechanisms Core Data uses (such
as having client-facing and primitive versions of the same property.)
Unfortunately, because it manipulates the class metadata at runtime, this
framework is also fatally stuck in the Obj-C world, and I haven’t found an
alternative approach for Swift.

I used Core Data for a major project — years ago, around the time Leopard came
out — and it was incredibly painful: 6 months of utter misery. It’s one of
those magical Apple technology solutions that’s clever as all get-out, but
totally inscrutable. Core Data doesn’t fulfill a design that’s documented
somewhere, its design is … whatever its implementation does. Sometimes that
makes sense, sometimes it doesn’t.
I think Core Data is great for Apple’s internal use (e.g. in older versions of
iTunes/iPhoto/Photos), and perhaps feasible for 3rd party developers if you’re
dealing with tens of thousands of objects (for performance reasons). It may
have become more usable over the years, but I promised myself I’d never go near
it again.
