SwiftData has introduced several new features and improvements at WWDC 2024. Here are some of the highlights:
-
Custom Data Stores: SwiftData now allows you to use custom data stores, enabling you to store data using alternative backends like SQLite, a remote web service, or even a collection of JSON files. This flexibility is achieved through a new datastore protocol, which supports any persistence backend (Create a custom data store with SwiftData).
-
Schema Macros: A new schema macro helps avoid duplicate models, making it easier to set up and configure model containers (What’s new in SwiftData).
-
Index and Unique Constraints: The addition of index and unique constraints improves query efficiency and ensures data integrity by preventing duplicate entries (Platforms State of the Union).
-
History API: SwiftData now 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 web service (What’s new in SwiftData).
-
Xcode Previews: The new previewable macro works well with SwiftData, making it easier to work with queries while iterating on views (Platforms State of the Union).
These updates make SwiftData a more powerful and flexible framework for managing app data across Apple's platforms.
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.

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.
