title: Cannot find module FBSDKCoreKit Cocoapods
body: <p>I'm trying to integrate facebook into my app using CocoaPods, using the use_frameworks! tag, and according to facebook's <a href="https://developers.facebook.com/docs/ios/getting-started/advanced" rel="noreferrer">instructions here</a>, also included the pod bolts.  When I try use <code>import FBSDKCoreKit</code> in my appdelegate, I get a no such module 'FBSDKCoreKit error.  I've included my podfile below:</p>
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  platform :ios, '9.2'
  use_frameworks!
  pod 'Bolts'
  pod 'Alamofire', '~&gt; 3.0'
  pod 'FBSDKCoreKit'
  pod 'FBSDKShareKit'
  pod 'FBSDKLoginKit'
  </code></pre>
  <p>Additionally, in my Pods folder, there is a question mark next to Bolts, FBSDKCoreKit, and FBSDKSharekit, but not one next to alamofire, which I had been using previously.  In the Frameworks folder in my Pods project, FBSDKCoreKit and Bolts are listed there, but are both red.
  Any ideas?  I've tried cleaning my project, and reinstalling and updating the pods.</p>
