    # Runs SwiftInfo and prints the results to the pull request.
    # You must have [SwiftInfo](https://github.com/rockbruno/SwiftInfo) installed
    # somewhere in your project.
    # You can detect that SwiftInfo is running specifically for Danger
    # by adding a `if isInPullRequestMode` condition in your Infofile.
    # You can use this condition to extract different rules and prevent saving the new output.
    # @example Run SwiftInfo
    #
    #          swiftinfo.run './Pods/SwiftInfo/bin/swiftinfo'
    #
    # @see  rockbruno/danger-SwiftInfo
    # @tags swift, xcode, swiftinfo, ios
