A Swift macro is a feature in the Swift programming language that acts as a compiler plugin. It takes the syntax tree of your code as input and returns transformed code as output. This allows developers to reduce repetitive boilerplate code and create more expressive APIs. Macros are part of Swift's efforts to enhance the language's flexibility and expressiveness, enabling developers to write more efficient and maintainable code.

A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
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.
