title: Library? Static? Dynamic? Or Framework? Project inside another project
body: <p>I have an existing iOS app and want to add a large chunk of code that I've been developing as another project just for ease of testing. The new chunk basically deals with saving an image to various sharing services, etc.. Because that sharing code needs a lot of testing and future updating, I was wondering what the best way to incorporate that code chunk into my existing app.</p>
  
  <p>I don't know if it should be a static library, dynamic library or a framework, and honestly, I'm not really sure what the difference is, or how I should go about it and get it set up in Xcode.</p>
  
  <p>All I know is that I need/want to keep a separate testing and updating app for the sharing code and have the main app use it.</p>
