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:
-
Meet Swift Testing: This session introduced the
expectandrequiremacros, which are used for testing in Swift. Theexpectmacro allows you to pass any expression and provides detailed results if it fails. Therequiremacro 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. -
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.

Xcode essentials: This session discussed the use of macros in debugging, suggesting alternatives like
Oslogfor 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.
Explore Swift performance
Discover how Swift balances abstraction and performance. Learn what elements of performance to consider and how the Swift optimizer affects them. Explore the different features of Swift and how they’re implemented to further understand the tradeoffs available that can impact performance.
Meet Swift Testing
Introducing Swift Testing: a new package for testing your code using Swift. Explore the building blocks of its powerful new API, discover how it can be applied in common testing workflows, and learn how it relates to XCTest and open source Swift.
Go further with Swift Testing
Learn how to write a sweet set of (test) suites using Swift Testing’s baked-in features. Discover how to take the building blocks further and use them to help expand tests to cover more scenarios, organize your tests across different suites, and optimize your tests to run in parallel.
What’s new in Xcode 16
Discover the latest productivity and performance improvements in Xcode 16. Learn about enhancements to code completion, diagnostics, and Xcode Previews. Find out more about updates in builds and explore improvements in debugging and Instruments.
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.
Xcode essentials
Edit, debug, commit, repeat. Explore the suite of tools in Xcode that help you iterate quickly when developing apps. Discover tips and tricks to help optimize and boost your development workflow.
