Last month I was given the opportunity to write an article for The Pragmatic Programmers great magazine called “PragPub”. I am happy to say that the article I wrote for them was published in this month’s edition. The article, titled “Touching the Core”, is a walk through Apple’s great addition to the Core Data API for the iPhone.

Specifically this article walks through using the NSFetchedResultsController and some best practices in its use. The magazine is available for free on their website, [The Pragmatic Bookshelf](http://pragprog.com/magazines).
