title: How do I get the current version of my iOS project in code?
body: <p>I would like to be able to get the current version of my iOS project/app as an <code>NSString</code> object without having to define a constant in a file somewhere. I don't want to change my version value in 2 places.</p>
  
  <p>The value needs to be updated when I bump my version in the Project target summary.</p>
