In the context of Apple's WWDC, a "macro" in Swift is a flexible tool that acts as a compiler plugin. It takes the syntax tree as input and returns transformed code as output. Macros are used to extend the capabilities of Swift by allowing developers to write code that can be transformed at compile time, providing a way to automate repetitive tasks or introduce new language features.
For more detailed information on macros, you can refer to the session titled "A Swift Tour: Explore Swift’s features and design" where macros are discussed. If you're interested in learning more about how macros can be used in testing, the session "Meet Swift Testing" also covers the use of macros like expect and require for testing purposes.
