title: XCode 7: AWS S3 Header file not found using Cocoa Pods
body: <p>I'm trying to get an existing Objective-C project to build in XCode 7 on OS X 10.11 (El Capitan).  I grabbed the source from a repository, ran <code>pod install</code>, and then opened up the <code>.xcworkspace</code> file and tried to build. It fails to find 'S3.h' which should be getting installed by Pods.  </p>
  
  <p>Here is the Pod file:</p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  platform :ios, '8.0'
  
  target 'App' do
  
  pod "AWSiOSSDKv2"
  pod "AWSCognitoSync"
  
  end
  
  target 'AppTests' do
  end
  </code></pre>
  
  <p>Which generates the following <code>Pods-App.release.xcconfig</code>:</p>
  
  <pre><code>GCC_PREPROCESSOR_DEFINITIONS = $(inherited) COCOAPODS=1

  </code></pre>
  
  <p>When I then go to build, it fails to find <code>S3.h</code> even though it seems to find other files such as <code>AWSCore.h</code>.  </p>
  
  <p>This project was building successfully on XCode 6.3 about 6 months ago.  Has something changed with the AWS SDK in the last 6 months? Is there some other configuration change that I need to make now that I'm using XCode 7.0.1? </p>
