Swift 6 introduces several notable features and improvements that enhance portability, performance, and the overall developer experience. Here are some key highlights:
-
Data Race Safety: Swift 6 introduces a new language mode that provides data race safety guarantees, helping developers write correct concurrent programs. This mode is opt-in and can be adopted module by module. It ensures that data races, which are typically runtime issues, are caught at compile time (Platforms State of the Union).
-
Non-Copyable Types: Swift 6 introduces non-copyable types, which are types that cannot be copied. This feature is useful for managing resources more efficiently and ensuring that certain types of data are not inadvertently duplicated (What’s new in Swift).
-
Embedded Swift: A new subset of the Swift language called Embedded Swift is introduced, which is designed for highly constrained environments like operating system kernels and microcontrollers (Platforms State of the Union).
-
Swift Testing: An all-new testing framework named Swift Testing is introduced, which provides expressive APIs to simplify writing tests. This framework is built from the ground up for Swift (Platforms State of the Union).
-
Concurrency Improvements: Swift 6 includes enhancements to concurrency, such as improved data race checking and complete concurrency checking. This ensures that non-sendable values are safely passed across isolation boundaries (What’s new in Swift).
-
C++ Interoperability: Swift 6 continues to improve interoperability with C++, making it easier to integrate Swift with existing C++ codebases (What’s new in Swift).
-
Swift's New Space on GitHub: The Swift project is moving to a new organization on GitHub, which will include the Swift Compiler foundation and many more ecosystem packages (What’s new in Swift).

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.
