I do not know if what i write is exactly helpful, but here is what i know:

AFIncrementalStore has some serious issues and is apparently abandoned by it's creator as it is incompatible with AFNetworking v. 2

The issues arise from the fact that AFIS tries to be more than an incremental store. Incremental store operates only inside its overriden methods and AFIS does this to immediately return objects from the backing store. However, when request finally comes in it cannot add objects this way. It adds them to the backing store and then tries to refresh the objects in their contexts. This behaviour was not evisioned by Core Data creators and results in unstable behaviour - AFIS sometimes has very long response times and sometimes objects do not refresh properly. Furthermore, if you use NSFetchedResultsController to feed table views, some callbacks are called often ans some never.

I spent a lot of time trying to get this working but it probably is impossible - you have to cheat core data that you are adding objects to the context while never doing so.

And back to your question - if you really want to use it - you basically have to write all those methods for twitter. This is a hard job but twitter has to have some object model and some id's assigned to each object. I did this for my API's but it's like one or two days of hard work - and i do not have so much time to write it here.
