At WWDC 2024, Apple introduced Swift 6, which brings several new features and improvements to the Swift programming language. One of the key highlights of Swift 6 is the introduction of a new language mode that provides data race safety guarantees, helping developers write correct concurrent programs. This new language mode is opt-in, allowing developers to enable it when they are ready to tackle data races in their code.
Swift 6 also includes improvements to concurrency, generics, and introduces a new embedded Swift subset for targeting highly constrained environments like operating system kernels and microcontrollers. Additionally, a new testing framework called Swift Testing was introduced, which offers expressive APIs to simplify writing tests.
For more detailed information on Swift 6, you can refer to the following sessions from WWDC 2024:
- Platforms State of the Union (27:44) - This session provides an overview of Swift 6 and its new features, including data race safety.
- What’s new in Swift (26:07) - This session covers the new language mode and data race safety in Swift 6, along with other language updates.
- Migrate your app to Swift 6 (03:20) - This session provides practical guidance on enabling the Swift 6 language mode and migrating your app to take advantage of the new features.
These sessions will give you a comprehensive understanding of the advancements in Swift 6 and how to adopt them in your projects.
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.
Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.

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”.
Go small with Embedded Swift
Embedded Swift brings the safety and expressivity of Swift to constrained environments. Explore how Embedded Swift runs on a variety of microcontrollers through a demonstration using an off-the-shelf Matter device. Learn how the Embedded Swift subset packs the benefits of Swift into a tiny footprint with no runtime, and discover plenty of resources to start your own Embedded Swift adventure.
What’s new in Xcode 16
Discover the latest productivity and performance improvements in Xcode 16. Learn about enhancements to code completion, diagnostics, and Xcode Previews. Find out more about updates in builds and explore improvements in debugging and Instruments.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
