Installation

brew install swiftlint

Usage

Integrate SwiftLint into an Xcode scheme to get warnings and errors displayed in the IDE. Just add a new “Run Script Phase” with:

if which swiftlint >/dev/null; then
  swiftlint
else
  echo "warning: SwiftLint not installed, download from https://github.com/realm/SwiftLint"
fi
