Swift 6 introduces several new features and improvements aimed at enhancing portability, performance, and the overall developer experience. Here are some of the 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, allowing developers to adopt it module by module and interoperate with dependencies that may not have migrated yet. Platforms State of the Union
-
Non-Copyable Types: Swift 6 introduces non-copyable types, which suppress the default copyability of Swift types. This feature is useful for scenarios where unique ownership is required, such as managing system resources like files. What’s new in Swift
-
Embedded Swift: A new language subset called Embedded Swift is introduced, which can run on highly constrained systems like operating system kernels and microcontrollers. What’s new in Swift
-
Swift Testing: An all-new testing framework named Swift Testing is introduced, offering expressive APIs that simplify writing tests. Platforms State of the Union
-
Concurrency Improvements: Enhancements to concurrency, including improvements to generics and a new embedded Swift subset, are part of Swift 6's offerings. Platforms State of the Union
-
Swift's New Space: The Swift project is moving to a new organization on GitHub, which will include the Swift Compiler foundation and other 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.
