Core Data is a great option for managing your iOS app's data. As Black Pixel Developer Michael Gachet explains in his article "Some Lessons Learned on Core Data," this Apple framework allows you to:

  • Define entities with properties (called attributes) and relationships with other entities (one-to-one, one-to-many, or many-to-many). This is what you do when you create your Core Data model in Xcode.
  • Create, delete, retrieve, and, more generally, manage instances of those entities (called managed objects) at runtime.
  • Persist those managed objects to memory or disk.

Using Core Data saves you time by optimizing the development cycle. It also provides a consistent and robust way to manage persistent data. To help you get started, take a look at our graphic that simplifies some of Core Data's key components, and check out Black Pixel Developer Jared Sinclair's tutorial on how to add Core Data to a project.
