Some of the new developments for Swift Data presented at WWDC 2024 include:
-
Custom Data Stores: Swift Data now supports custom data stores, allowing you to use alternative backends like SQLite, remote web services, or even collections of JSON files. This flexibility enables the use of Swift Data's API with various storage solutions (Platforms State of the Union).
-
Schema Macros: A new schema macro helps avoid duplicate models, making it easier to define and manage your data models (What’s new in SwiftData).
-
Index and Unique Macros: The addition of the
indexanduniquemacros improves query efficiency and ensures data integrity by preventing duplicate entries (Platforms State of the Union). -
History API: Swift Data 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).
-
Model Containers: New ways to set up and configure model containers have been introduced, allowing for more tailored data management (What’s new in SwiftData).
-
Expression Macro: A new macro to improve performance by optimizing queries with complex filters (What’s new in SwiftData).
-
Previewable Macro: This macro works great with Swift Data, making it easier to work with your queries while iterating on views (Platforms State of the Union).
For a more detailed overview, you can check out the sessions:
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.
