title: Run ruby script from OS X Application
body: <p>I'd like to write an OS X application that can execute some code that is really simple to write in ruby and that I prefer not to port in swift. 
  Is it possible to include somehow ruby scripts into an OS X app and then call and get data from this script exchanging info with my swift code? For example I can write the function "return_random" in Ruby and call it from swift getting the result that comes from that function? </p>
  
  <p>I know... it sounds really complex but it would be extremely useful! </p>
  
  <p>Thanks </p>
