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.
- 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.
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
@AddCompletionHandlerand@AddAsync.
- 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.
- Exploring Swift Macros
- Sergey goes over creating a macro for a memberwise initaliser step by step with tests and convenience methods for SwiftSyntax
- Automating RawRepresentable Conformance with Swift Macros
- Nikita goes over creating a macro for automating the String RawRepresentable conformance.
- EnvironmentValues & EnvironmentValue: Bypass boilerplate code and swiftly support new SwiftUI Environment Keys and Values.
- SFSymbols Macro: A Swift Macro for "type-safe" SF Symbols.
- Coding Keys: Effortlessly generate CodingKeys for converting
snake_casetolowerCamelCase. - Builder pattern: Apply the Builder Pattern with ease by generating a
Builderhelper class, mimicking stored properties of the associated struct.
- Power Assert: Adds assertions that can automatically produce information about the values being evaluated, and present it in an easily digestible form.
- Spyable: A Swift macro that simplifies and automates the process of creating spies for testing. Using the
@Spyableannotation on a protocol, the macro generates a spy class that implements the same interface as the protocol and keeps track of interactions with its methods and properties.
- SwiftRequest: SwiftRequest is a lightweight, type-safe HTTP client for Swift, streamlining the construction and execution of HTTP request build on top of Macros.
