Swift Macros are a powerful feature in the Swift programming language that act as compiler plugins. They take the syntax tree of Swift code as input and return transformed code as output. This allows developers to reduce repetitive boilerplate code and create more expressive APIs. Macros are part of Swift's toolset that includes other features like property wrappers and result builders, which help in writing elegant and powerful code. If you're interested in learning more about Swift Macros, you might want to watch the session "Expand on Swift Macros" mentioned in the context.

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.
