Overview
Apple's framework for managing object graphs and data persistence in iOS and macOS applications. CoreData provides an abstraction layer over SQLite, offering features like object-relational mapping, change tracking, undo/redo support, and memory-efficient data handling. It is essential for iOS apps that need to store structured data locally.
