It seems like you're interested in diffable data sources, but the provided context doesn't specifically mention them. However, I can provide information on related topics discussed at WWDC, such as SwiftData and custom data stores, which are relevant to data management in Swift applications.
For example, the session Create a custom data store with SwiftData covers how to use SwiftData with your own persistence backend, allowing you to use any document, file format, or persistence backend of your choice. This session might be useful if you're looking into advanced data handling techniques in Swift.
If you have more specific questions about data handling in Swift or other topics from WWDC, feel free to ask!
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.
