What is persistent store in core data?

A persistent store is the interface between the coordinator and the permanent state of the object graph for both reading and writing. When a change is pushed onto the store, the change becomes a permanent part of the object state, meaning the position of the storage in memory or on disk is not relevant.

How much data can I store in core data?

1 Answer. Core Data has no hard storage capacity, so you're pretty much just limited by the available disk space on the system. On iOS (and most of the time on OS X) Core Data is backed by SQLite, so if there's any restriction, it's in the size of the backing SQLite database.
