The current version of Swift is Swift 6. This version introduces several new features and improvements, including a new language mode that achieves data race safety, expanding Swift's safety guarantees to concurrent programs. Additionally, Swift 6 includes a new language subset called embedded Swift, which can run on highly constrained systems. Other notable updates include non-copyable types and enhancements to the concurrency model.
For more details, you can refer to the session What’s new in Swift from WWDC 2024.

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.
