SwiftData has introduced several new features and improvements. Here are the highlights:
-
Schema Macro: A new schema macro helps avoid duplicate models, making it easier to manage your data models.
-
Model Containers: There are new ways to set up and configure model containers, enhancing how you manage your app's data.
-
Query Optimization: SwiftData now allows for more complex filters and includes a new macro to improve query performance.
-
Custom Data Stores: You can now use custom data stores, allowing SwiftData to work with various storage backends like SQLite, remote web services, or JSON files.
-
Data Store History: SwiftData provides access to the history of changes in a datastore, which is useful for tracking local changes that need to be synced to a remote service.
-
Index and Unique Constraints: New syntax additions like
indexanduniquehelp make queries more efficient and ensure data integrity by preventing duplicate entries.

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”.
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.
