If you’ve used services like Parse to prototype applications backed by
a database in the cloud, then you might want to check out Heroku’s new article
on building a web service based on a Core Data Model. It walks you
through spinning up a Heroku instance that takes the managed object model file
you would build in Xcode and turns it into an REST-like endpoint. Using the
NSIncrementalStore, you can access this web service as if it was
just a local Core Data database. Use an
NSFetchedResultsController like you
normally would, and boom, your table view is fed from the internet.
There’s a short video demonstrating how it all works currently living at
mobile.heroku.com. I see a lot of potential for prototyping. It’s
possible to use this as a synchronization strategy since you can add both local
and remote Core Data persistent stores and move or copy your managed objects
back and forth between them. The best part is that you don’t write the server.
It gets generated from your model file. Remarkable work.
