How to use Bundler with RubyMotion
If you don't have a RubyMotion app yet, generate one.
$ motion create myapp
$ cd myapp
You'll need to create a Gemfile. Here we're using bubblewrap.
gem 'bubble-wrap'
Then, set up your Rakefile to require your bundled gems at compile time.
Add this to the top of the file, right beneath the line `require 'motion/project'`
require 'bundler'
Bundler.require
Next, install your dependencies:
$ bundle install
Now you can just compile your app as normal.
$ bundle exec rake
