Core Data migration

To migrate from Core Data to SwiftData, you can utilize the SwiftData history feature, which allows you to track changes in your data models. This is particularly useful if you're using Core Data's persistent history and want to transition to SwiftData's history tracking. SwiftData provides a robust framework for managing your app's model layer, including persistence, schema migration, and synchronization with CloudKit.
For more detailed information on how to track model changes and manage data history, you can refer to the session Track model changes with SwiftData history (16:20).
Additionally, if you're interested in creating custom data stores with SwiftData, you can explore the session Create a custom data store with SwiftData (05:40), which discusses the DataStore protocol and how it supports features like migration, history tracking, and CloudKit sync.

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”.
