Core Data is a well-established framework for managing and persisting data in iOS applications. However, Apple has introduced Swift Data, which builds on the capabilities of Core Data while providing a more modern and flexible API.
Swift Data uses Core Data as its default storage backend, but it also allows for custom data stores, enabling developers to use alternative backends like SQLite, remote web services, or even JSON files. This flexibility makes Swift Data a powerful tool for data persistence in modern app development.
For more details on Swift Data and its capabilities, you can check out the following sessions from WWDC 2024:
These sessions cover the new features and improvements in Swift Data, including its integration with Core Data and the ability to create custom data stores.
Track model changes with SwiftData history
Reveal the history of your model’s changes with SwiftData! Use the history API to understand when data store changes occurred, and learn how to use this information to build features like remote server sync and out-of-process change handing in your app. We’ll also cover how you can build support for the history API into a custom data store.
Create a custom data store with SwiftData
Combine the power of SwiftData’s expressive, declarative modeling API with your own persistence backend. Learn how to build a custom data store and explore how to progressively add persistence features in your app. To get the most out of this session, watch “Meet SwiftData” and “Model your schema with SwiftData” from WWDC23.
What’s new in SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.
