via “annotation-driven code generation with documentation comments”
Meta-programming for Swift, stop writing boilerplate code.
Unique: Extracts code generation directives from documentation comments (/// sourcery: annotations) parsed by SwiftSyntax, allowing developers to declare generation intent inline with type definitions rather than in separate configuration files — the parsed annotations are available to templates as queryable metadata on Type objects
vs others: More discoverable than external configuration files (annotations live next to the code they affect) and more flexible than attribute-based approaches (e.g., @Codable) which require language-level support, though less type-safe than compile-time annotations
