When deciding between Core Data and Swift Data, it's important to consider the specific needs of your app. Swift Data is a newer framework introduced by Apple that simplifies building your app's model layer and persisting it across launches. It provides a lightweight API that integrates well with Swift, allowing you to define your schema with minimal additions to your Swift classes. Swift Data also supports custom data stores, enabling you to use different storage backends like SQLite, remote web services, or JSON files.
Core Data, on the other hand, is a mature and robust framework that has been around for a long time. It offers powerful features for data management, including object graph management, data persistence, and complex query capabilities.
If you are looking for a modern, flexible, and Swift-friendly approach, Swift Data might be the better choice, especially if you want to leverage its custom data store capabilities. However, if you need the advanced features and proven stability of Core Data, it remains a strong option.
For more details on Swift Data, you can refer to the session Create a custom data store with SwiftData (04:50) which discusses the new Datastore protocol and its capabilities.
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.
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”.
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.
