macros

It seems like you're interested in macros, particularly in the context of Swift and Xcode. At WWDC 2024, several sessions discussed the use of macros in Swift and Xcode:

1. Meet Swift Testing: This session introduced the expect and require macros, which are used for testing in Swift. The expect macro allows you to pass any expression and provides detailed results if it fails. The require macro is used to end a test early if an expectation fails, throwing an error if the expression is false. You can learn more about these macros in the Meet Swift Testing session.

2. A Swift Tour: Explore Swift’s features and design: This session touched on macros as a flexible tool in Swift, acting as compiler plugins that transform code. It also mentioned result builders and property wrappers as part of Swift's feature set. For more on macros, you might want to check out the A Swift Tour session.

3. Xcode essentials: This session discussed the use of macros in debugging, suggesting alternatives like Oslog for more structured logging. It emphasized the benefits of using macros for debugging purposes in Xcode. You can explore this further in the Xcode essentials session.

These sessions provide a comprehensive overview of how macros can be utilized in Swift and Xcode to enhance testing, debugging, and code transformation.
