#How to use Bundler with iOS projects

You probably stuck with situation when after finishing for example bundle install && bundle exec pod install Bundler couldn't access gems which he just download. Some of you may think "RVM is the answer!" and yes it is, but what if it is not?

##Don't use macOS's gems. Just DON'T.

1. Establish that you will don't use macOS's gems and RVM.
2. Go to your_app_dir
3. Make sure you have Gemfile if not create one
