Swift macros are a powerful feature that allows you to write Swift code that acts as a compiler plugin. They take the syntax tree as input and return transformed code as output. This can be particularly useful for reducing repetitive boilerplate code and enabling more expressive APIs.
For a deeper understanding of Swift macros, you can watch the session titled "Expand on Swift macros" mentioned in the A Swift Tour: Explore Swift’s features and design session.
Here are some key points about Swift macros:
- Compiler Plugin: Macros act as a compiler plugin, transforming the syntax tree.
- Boilerplate Reduction: They help reduce repetitive boilerplate code.
- Expressive APIs: Enable the creation of more expressive APIs.
If you want to explore more about Swift's features and design, you can check out the session "A Swift Tour: Explore Swift’s features and design" which covers various aspects of Swift, including macros, result builders, and property wrappers.
