  17. The comparison doesn’t work. What can I do?

    Don’t worry! The most popular reason for it is wrong Command Line Tool path in your Xcode. You should have the same Command Line Tool as your Xcode version. Go to Preferences window from the menu bar:
    Xcode > Preferences > Locations > Command Line Tools
    You need to set correct version of the command line tool. For example, if you have Xcode 8.3.3 you should select same Command Line Tool.
