    126 shares
    Core Data has been around for many years on OS X and it didn't take Apple long to bring it to iOS. Even though the framework doesn't get as much attention as extensions or handoff, it continues to evolve year over year, and this year, with the release of iOS 8 and OS X Yosemite, is no different. Apple introduced a few new features to the Core Data framework, but the most notable are batch updates and asynchronous fetching. Developers have been asking for these features for many years and Apple finally found a way to integrate them into Core Data. In this tutorial, I will show you how batch updates work and what they mean for the Core Data framework.Read More…

    If you're developing a small or simple application, then you probably don't see the benefit of running Core Data operations in the background. However, what would happen if you imported hundreds or thousands of records on the main thread during the first launch of your application? The consequences could be dramatic. For example, your application could be killed by Apple's watchdog for taking too long to launch. In this article, we take a look at the dangers when using Core Data on multiple threads and we explore several solutions to tackle the problem.Read More…

    Core Data from Scratch: Subclassing NSManagedObjectPreview image@2x
    131 shares
    Earlier in this series, we created Done, a simple application to learn more about the NSFetchedResultsController class. In that project, we used key value coding (KVC) and key value observing (KVO) to create and update records. This works fine, but from the moment your project has any kind of complexity, you'll quickly run into issues. Subclassing NSManagedObject makes this much easier.Read More…
