title: import module from cocoa pod has error but is still able to build the project
body: <p>I am new to creating cocoa pod, here is some questions which maybe easy for you, but these do give me a headache. here my story:</p>
  
  <p>I create a swift framework project(called project A), and then put it as a cocoa pod(it does is a complicated process). and then I create another single view swift project(called project B), and then use pod to integrate the project A into project B. In my project B, I have an error when I use a  class from project A, it says: <code>"No such module '**class name**'"</code>.</p>
  
  <p>So I have two questions here:</p>
  
  <ol>
  <li><p>when I create the swift framework project, how come it has an .h file in the project: the file looks like this:</p>
  
  <pre><code>import &lt;UIKit/UIKit.h&gt;
  
  //! Project version number for VLEBluetoothKit.
  FOUNDATION_EXPORT double projectnameVersionNumber;
  
  //! Project version string for VLEBluetoothKit.
  FOUNDATION_EXPORT const unsigned char projectnameVersionString[];
  
  // In this header, you should import all the public headers of your framework using statements like #import &lt;projectname/PublicHeader.h&gt;
  </code></pre>
  
  <ol start="2">
  <li><p>why I have the error in project B, I can still build it successfully?</p></li>
  <li><p>how can I solve this error.</p></li>
  </ol></li>
  </ol>
  
  <p>Thanks a lot guys. please give me a hand</p>
