title: Include ".framework" file to cocoapods
body: <p>I'm trying to add "Custom.framework" to my pod (cocoapods).
  And I'm a bit stuck with pod spec setup. I've done following:</p>
  
  <pre><code>
  s.resources = ['Resources/Custom.framework']
  s.preserve_paths = "Resources/Custom.framework"
  s.frameworks  = "UIKit", "Custom"
  </code></pre>
  
  <p>But in project where I'm using this pod, I'm getting error</p>
  
  <pre><code>&lt;Custom/Custom.h&gt; not found
  </code></pre>
  
  <p>or something similar.</p>
  
  <p>I'm stuck already for a few hours and I can't find answer to my question in google.</p>
  
  <p>BR, Pavlo.</p>
