Fastlane with RVM on macOS

Why should you use RVM instead of using system’s Ruby?

It turns out that system’s Ruby doesn’t update fast enough, when you try to update Fastlane, it may be broken. :|

Installing RVM on macOS

1. Install Homebrew (I think most of you should have it installed)
2. Install gnupg with brew install gnupg
3. Following the steps in https://rvm.io/rvm/install to install RVM
4. If you are using fish shell, you may need to follow this guide to perform some extra steps: https://rvm.io/integration/fish
5. Select a version of Ruby to install by calling rvm list known
6. Install Ruby rvm install 2.5.1 (for example)
7. Use that version rvm use 2.5.1
8. Verify it ruby -v
