%description
SwiftLint is a tool to enforce Swift style and conventions, loosely based on
the now archived GitHub Swift Style Guide. SwiftLint enforces the style guide
rules that are generally accepted by the Swift community. These rules are well
described in popular style guides like Kodeco's Swift Style Guide.

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