What is Core Data on iPhone?

Core Data is an object graph and persistence framework provided by Apple in the macOS and iOS operating systems. It was introduced in Mac OS X 10.4 Tiger and iOS with iPhone SDK 3.0.

Should I use Core Data iOS?

The next time you need to store data, you should have a better idea of your options.
