To migrate from Core Data to SwiftData, you can follow the guidance provided in the WWDC sessions. Here are some key points and resources that might help you:

  1. SwiftData Introduction and Migration: SwiftData was introduced to provide a modern and efficient way to model and persist app data across Apple's platforms. It supports schema migration, which is crucial for transitioning from Core Data. You can learn more about this in the session SwiftData: Dive into inheritance and schema migration.

  2. History Tracking: If you are using Core Data's persistent history, you can migrate to SwiftData's history tracking. This feature allows you to track changes in your data models, which is useful for syncing and other operations. More details can be found in the session Track model changes with SwiftData history.

  3. Custom Data Stores: SwiftData allows you to create custom data stores, which can be useful if you need to maintain compatibility with existing Core Data setups or if you want to use a different backend. This is covered in the session Create a custom data store with SwiftData.

  4. Schema Migration: SwiftData supports schema migration, which is essential for evolving your data models over time. This includes handling changes in model structure and ensuring data integrity during updates. You can explore this topic further in the session SwiftData: Dive into inheritance and schema migration.

By leveraging these resources, you can effectively plan and execute a migration from Core Data to SwiftData, taking advantage of SwiftData's modern features and capabilities.
