Core Data

Overview

Core principle: Core Data is a mature object graph and persistence framework. Use it when needing features SwiftData doesn't support, or when targeting older iOS versions.

When to use Core Data vs SwiftData:

• SwiftData (iOS 17+) — New apps, simpler API, Swift-native
• Core Data — iOS 16 and earlier, advanced features, existing codebases
