Swift macros are a recent addition to the Swift language, designed to simplify repetitive code patterns and reduce boilerplate in Swift codebases. With macros, developers can define reusable code snippets that are expanded at compile time, leading to more readable and maintainable code. This feature draws inspiration from metaprogramming techniques and helps streamline common tasks, such as code generation, logging, and more.
Unlike traditional functions or methods that are invoked at runtime, macros operate at the level of code generation, making them highly efficient for repetitive tasks. In Swift, macros are used to automate repetitive patterns by generating code for developers, keeping codebases cleaner and more concise.
Swift macros are part of the Swift compiler’s metaprogramming capabilities, which allow developers to define and reuse patterns without needing complex, error-prone manual coding. They can perform actions such as automatic property synthesis, error checking, and even custom logging.
