How This Book Approaches Core Data
This book shows how to use Core Data with working examples — it’s not an extended API manual. We deliberately focus on best practices within the context of complete examples. We do so because, in our experience, stringing all the parts of Core Data together correctly is where most challenges occur.
In addition, this book provides an in-depth explanation of Core Data’s inner workings. Understanding this flexible framework helps you make the right decisions and, at the
same time, keep your code simple and approachable. This is particularly true when it comes to concurrency and performance.
