To implement animated updates with a diffable data source, you can leverage the capabilities of SwiftData, particularly its history tracking features. SwiftData provides a way to track changes in your data store over time, which can be useful for updating your UI efficiently.

In the session Track model changes with SwiftData history, it is explained how SwiftData records transactions and changes, allowing you to query and process these changes in the order they occurred. This can be particularly useful for updating UI components like a diffable data source, as you can efficiently determine which models have been inserted, updated, or deleted.

By using SwiftData's history API, you can fetch changes and update your UI accordingly. This involves fetching transactions, processing the changes, and then updating your user interface. This approach ensures that your UI reflects the most recent state of your data store, and can be animated to show changes smoothly.

For more detailed information, you can refer to the session Track model changes with SwiftData history which covers the fundamentals of using SwiftData history to track and process changes.
