Chapter 12. Troubleshooting Core Data
IN THIS CHAPTER
When things go amiss with Core Data, the symptoms and error messages can seem obscure, even if you’ve been using it for a while. You can’t very well fix your code if you don’t understand what’s wrong. This chapter will help you diagnose and fix some of the most common Core Data problems.
