Pods install not installing all files in AFNetworking on existing project
<p>Cocoapods is not installing all the files in AFNetworking 2.6.0 on an existing project. See attached images. The other two pods, ECSlidingViewController and DateTools, installed just fine.</p>

<p>Any suggestions on how to resolve the missing files upon <code>pod install</code> of AFNetworking on new setups?</p>

<p>Podfile: </p>

<pre><code>platform :ios, '7.0'
pod 'AFNetworking'
pod 'ECSlidingViewController', '~&gt; 2.0'
pod 'DateTools'
</code></pre>

<p>Podfile.lock:  </p>

<ul>
<li>uses AFNetworking version 2.6.0</li>
<li>created using Cocoapods 0.38.2</li>
</ul>

<p>Pod install on new setup:<br>
These are the only AFNetworking files installed on a new system of the existing project. It's missing folders/files - NSURLSession, Reachability, Security, and Serialization.
