Core Data by Tutorials teaches you everything you need to know about Core Data, starting with the basics like setting up your own Core Data Stack and moving all the way to advanced topics like syncing with iCloud, migration, performance, multithreading, and more.
Here are some of the changes in this update:
Swift 2. All code has now been updated to Swift 2. This includes using the new error handling model — moving away from the complexities of NSError.
New uniqueness model constraint. iOS 9 introduces the ability to specify that an attribute should be unique across all objects.
Bugfixes. All chapters have been fully re-tested and tech edited and are verified as 100% working.
This is a free update for existing PDF customers – you can download the update on your My Loot page.
