What's New in Swift
At WWDC 2024, several new features and improvements were introduced for Swift:
-
Swift Data Enhancements: Swift Data has been expanded with new capabilities, such as the addition of
indexanduniqueto make queries more efficient and ensure no duplicate entries in a set of properties. The newpreviewablemacro also enhances working with queries while iterating on views. Swift Data now supports custom data stores, allowing you to use alternative backends like SQLite or a remote web service. It also 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. Platforms State of the Union -
Swift 6 Language Mode: The new Swift 6 language mode introduces compile-time data race safety. SwiftUI has improved its APIs to make it easier to adopt this new language mode in your apps. Views in SwiftUI are now evaluated on the main actor, and the view protocol is marked with the main actor annotation, isolating all types conforming to view to the main actor by default.

Swift's 10th Anniversary: Swift celebrated its 10th birthday, highlighting its safety, speed, and approachability. The language's built-in C and C++ interoperability makes it a compelling choice for performance-sensitive and secure code. SwiftUI continues to evolve, allowing more code sharing across devices and improving the developer experience with previews, customizations, and interoperability.

These updates make Swift an even more powerful and flexible language for developers, enhancing productivity and enabling more efficient and expressive code.
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 SwiftUI
Learn how you can use SwiftUI to build great apps for any Apple platform. Explore a fresh new look and feel for tabs and documents on iPadOS. Improve your window management with new windowing APIs, and gain more control over immersive spaces and volumes in your visionOS apps. We’ll also take you through other exciting refinements that help you make expressive charts, customize and layout text, and so much more.
Enhance your UI animations and transitions
Explore how to adopt the zoom transition in navigation and presentations to increase the sense of continuity in your app, and learn how to animate UIKit views with SwiftUI animations to make it easier to build animations that feel continuous.
