MacRuby notes series: taking the pain out of Core Data

Continuing my “MacRuby notes series” aimed at Rails programmers adopting MacRuby…

In part 1 I discuss a direct comparison of Core Data and ActiveRecord to help you understand the differences between the two.

In part 2 I dig a little deeper, presenting terminology and sample code to help you understand how Core Data retrieval works. I also give you a tidy singleton class to include in your own MacRuby apps to DRY up Core Data and make using it a LOT simpler.
