How do SQLite and Core Data compare for iOS development?

SQLite is a lightweight database engine, while Core Data is an object graph and persistence framework. Core Data can use SQLite as a storage option, but it also provides additional features like data modeling and change tracking.

What are the advantages of using Core Data over SQLite?

Core Data offers a higher level of abstraction, making it easier to manage complex data models. It also provides features like data validation, undo management, and automatic change tracking, which can simplify development.

Are there any performance differences between the two?

Performance can vary based on use cases. SQLite is generally faster for simple queries, while Core Data may introduce overhead due to its additional features. However, Core Data can optimize performance with batch processing and caching.

When should I choose SQLite instead of Core Data?

Choose SQLite if you need a lightweight, fast solution for simple data storage without the need for complex data relationships or features. It's ideal for smaller apps or when you want direct control over SQL queries.
