Core Data

From simple persistency to multithreading and syncing: Core Data best practices by example.

This book strives to give you clear guidelines for how to get the most out of Core Data, while avoiding the pitfalls of this flexible and powerful framework. We start with a simple example app and extend it step by step, as we talk about relationships, advanced data types, concurrency, syncing, and many other topics.
Later on we go well beyond what’s needed for the basic example app: we’ll discuss in-depth how Core Data works behind the scenes, how to get great performance, the trade-offs between different Core Data setups, and how to debug and profile your Core Data code.
