A command-line tool and Xcode extension for formatting Swift code with extensive rule customization.
SwiftFormat is a command-line tool and Xcode extension that automatically reformats Swift code to enforce consistent style. It goes beyond basic whitespace adjustments by applying idiomatic Swift corrections, such as handling implicit self and redundant syntax, making it a comprehensive formatting solution for Swift projects.
Swift developers and teams working on collaborative projects who want to maintain a consistent code style without manual effort, especially those using Xcode or integrating formatting into CI/CD pipelines.
Developers choose SwiftFormat for its extensive rule customization, multiple integration options, and ability to handle complex Swift idioms automatically, reducing style conflicts and ensuring code consistency across teams.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Over 50 configurable rules allow fine-grained control, from whitespace to Swift idioms like implicit self, as detailed in the Rules.md file and command-line options.
Supports command-line, Xcode extensions, build phases, Git hooks, SPM plugins, and CI/CD, with step-by-step installation guides for each method in the README.
Runs on macOS, Linux, and Windows, and supports multiple Swift versions and language modes, making it suitable for diverse development environments.
Includes a lint mode with error codes and GitHub Actions reporter, ideal for automated style checks in continuous integration pipelines, as described in the linting section.
The known issues section lists rules like redundantType and enumNamespaces that can introduce compilation errors in edge cases, requiring manual overrides or rule disabling.
Managing .swiftformat files, per-directory overrides, and inline directives can be cumbersome, especially in large teams or projects with varying style requirements.
The README notes the Xcode extension menu sometimes disappears, requiring troubleshooting steps that can disrupt developer workflow and reliability.
