The major new feature of Swift 6 is the introduction of a new language mode that provides data race safety guarantees, which helps in writing correct concurrent programs. This new language mode is opt-in and allows developers to diagnose concurrent access to memory at compile time, making concurrent programming easier and safer. Additionally, Swift 6 includes improvements to concurrency, generics, and introduces a new embedded Swift subset for targeting highly constrained environments like operating system kernels and microcontrollers.

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.
