title: Product version number in swift code
body: <p>Is there's a way to get the product version number inside swift code, like</p>
  
  <pre><code>println("Running version \($PRODUCT_VERSION)")
  </code></pre>
  
  <p>I have to define some standartUserDefaults, that are bound to the Version and build number and i don't like to put them into my code when it's there at build time. </p>
  
  <p>NSProcessInfo don't have the build number. 
  Any suggestions for me? </p>
