To get started with Swift macros, you can watch the session titled "A Swift Tour: Explore Swift’s features and design" from WWDC 2024. This session provides an overview of Swift's features, including macros, which are a flexible tool in Swift that act as compiler plugins. They take the syntax tree as input and return transformed code as output. For more detailed information on Swift macros, you might want to look for sessions specifically focused on expanding Swift macros.
If you're interested in learning more about Swift's development workflow and improvements, the session "What’s new in Swift" from WWDC 2025 might also be helpful. It covers various aspects of Swift development, including macro-based APIs and improvements in build times.
For a more in-depth exploration of Swift macros, you can refer to the chapter on "Extensibility" in the session "A Swift Tour: Explore Swift’s features and design" here.
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.
Explore Swift and Java interoperability
Learn how you can mix Swift and Java in a single codebase. We’ll introduce the swift-java interoperability project, which allows you to use Swift in Java programs or vice versa. We’ll show you how to use the tools and libraries offered by swift-java to write safe and performant code that interoperates between these two runtimes.
What’s new in Swift
Join us for an update on Swift. We’ll talk about workflow improvements that make you more productive, and new and modernized library APIs for fundamental programming tasks. We’ll show examples of Swift adoption throughout more layers of the software stack. Finally, we’ll explore new language features for both improving approachability of concurrency, and achieving peak performance when you need it.
