title: Sharing classes between Xcode projects
body: <p>A while ago I developed an iOS application using Xcode that and created a bunch of classes that work together to communicate with a RESTful API. Now I'm creating a second app, totally separate but communicates with the same API. I want to reuse these classes, what is the best way to approach this? Should I be do the via some Version control system? Or should I use an Xcode workspace?</p>
  
  <p>Thanks in advance for any help.</p>
