Yes, several new features for SwiftData were announced at WWDC 2024. Here are some of the key updates:
- Schema Macro: A new schema macro helps avoid duplicate models.
- Model Containers: New ways to set up and configure model containers.
- Query Optimization: Complex filters and a new macro to improve performance.
- Custom Data Stores: SwiftData now supports custom data stores, allowing you to use alternative backends like SQLite, remote web services, or JSON files.
- History API: Access to the history of changes in a datastore, useful for tracking local changes that need to be synced to a remote web service.
- Index and Unique Constraints: The addition of
indexanduniqueconstraints to make queries more efficient and ensure no duplicate entries. - Previewable Macro: A new macro that makes it easier to work with queries while iterating on views.

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”.

What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
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.
