You can build a lot of cool apps without using the material in this chapter. Before you slam this book closed, however, we recommend you keep reading. This chapter contains material that addresses some advanced Core Data topics that your particular applications may require, especially if securing user data is important to your application. You caught a glimpse of one of the topics, using NSFetchedResultsController, with the League Manager application in Chapter 3.
