title: Support CocoaPod and Carthage
body: <p>I've created and published a Cocoapod using <code>pod lib create</code>. Now I also want to support Carthage, but after adding the path to the GitHub project to my <code>Cartfile</code> and running <code>carthage update --platform iOS</code> I'm getting the following error:</p>
  
  <p><code>Dependency "" has no shared framework schemes for any of the platforms: iOS</code></p>
  
  <p>Any idea how to fix this?</p>
