Core Data is a very powerful framework for managing data, though it can be daunting to learn at first. It is hugely popular and well documented and has been around for years, both on iOS and OS X. The result is an easy-to-use framework for managing an object graph that is elegant to use and incredibly efficient in terms of memory usage.
In this course, Envato Tuts+ instructor Markus Mühlberger will show you how to use Core Data on iOS. You'll learn about the components of a Core Data stack, creating and manipulating data, relationships, filtering, and data migration. Along the way, you'll get to follow along as Markus builds a full-featured app for quiz masters, to create and edit quizzes.
