What is Core Data?

Core Data is Apple's framework for persisting complex object graphs and relational data on iOS. It provides an abstraction layer over SQLite with tools for defining data models, fetching, filtering, and observing changes. Core Data supports undo/redo, background data operations, and CloudKit integration for syncing data across a user's devices.
