An experimental tool to enforce Swift style and conventions, loosely based on GitHub's Swift Style Guide.

SwiftLint hooks into Clang and SourceKit to use the AST representation of your source files for more accurate results.

Using Homebrew

brew install swiftlint 

You can also install SwiftLint by downloading SwiftLint.pkg from the latest GitHub release and running it.

You can also build from source by cloning this project and running make install.

Integrate SwiftLint into an Xcode scheme to get warnings and errors displayed in the IDE. Just add a new "Run Script Phase" with /usr/local/bin/swiftlint as its contents.

To integrate SwiftLint with Atom install the linter-swiftlint package from APM.

$ swiftlint help Available commands: help Display general or command-specific help lint Print lint warnings and errors for the Swift files in the current directory (default command) rules Display the list of rules and examples version Display the current version of SwiftLint 

Run swiftlint in the directory containing the Swift files to lint. Directories will be searched recursively.

There are only a small number of rules currently implemented, but we hope the Swift community (that's you!) will contribute more over time. Pull requests are encouraged.

The rules that are currently implemented are mostly there as a starting point and are subject to change.

See the Source/SwiftLintFramework/Rules directory to see the currently implemented rules.
