Swift Macros 🚀

Swift Macros have brought in a new wave of possibilities. The aim of this project is to curate a list of community-created Macros and associated learning resources.

A lot of use-cases my Sourcery covered before can now be implemented by Swift Macros.

Learning Resources 📚

Tools

• Swift AST Explorer
  • This is extremely helpful when working with SwiftSyntax, I used this when writing Sourcery parser and you can leverage it to build your own Macros.

WWDC 2023:

Dive into Swift Macros with these WWDC sessions:

• Write Swift Macros: An introductory session on Macros, their roles, and workings with a basic example.
• Expand Swift Macros: A deeper exploration into crafting your Macros and testing their functionality.
• Example Swift Macros: Check out real-world examples from Apple, like @AddCompletionHandler and @AddAsync.

Community Blogs

• Swift Macros by SwiftLee
  • Antoine goes over the introduction of what Macros are and how you can build your own one with an example.
• How to Create Swift Macros in Xcode 15
  • Francesco goes over creating your first macro with testing and some interesting tidbits.

Macros 💻

SwiftUI

• EnvironmentValues & EnvironmentValue: Bypass boilerplate code and swiftly support new SwiftUI Environment Keys and Values.

Models

• Coding Keys: Effortlessly generate CodingKeys for converting snake_case to lowerCamelCase.
• Builder pattern: Apply the Builder Pattern with ease by generating a Builder helper class, mimicking stored properties of the associated struct.
