Core Data
Apple's object graph and persistence framework for iOS and macOS. Core Data provides data modeling, persistence, caching, and undo functionality. It enables offline-first architectures where applications can function without network connectivity and synchronize data when available.
Implemented offline-first architecture for CatchPay marketplace
Core persistence layer for CatchSmart applications
Advanced CoreData usage in hybrid storage system for Airmee offline-first architecture
✨ Combined CoreData with SQLite and caching layers for sophisticated offline data management
Core Concepts
- • Managed Object Context - The working area for creating, editing, and fetching managed objects
- • Persistent Store Coordinator - The bridge between managed objects and the underlying data store
- • Entity modeling - Defining data models using the visual editor or code
- • Fetch requests and predicates - Querying data efficiently with filtering and sorting
Advanced Topics
- • Background context management for thread-safe operations
- • Migration strategies for schema evolution
- • Performance optimization with batch operations
- • Combining CoreData with other storage mechanisms
