title: Why can't CocoaPods access RealmSwift
body: <p>I'm trying to use Realm with Swift 2.0
  My Podfile is pretty simple:</p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  
  pod 'AWSS3', '~&gt; 2.2.0'
  
  # Realm Frameworks
  use_frameworks!
  pod 'RealmSwift', :git =&gt; 'https://github.com/realm/realm-cocoa.git', :branch =&gt; 'swift-2.0'
  </code></pre>
  
  <p>But I'm getting</p>
  
  <pre><code>[!] Unable to satisfy the following requirements:
  
  - `RealmSwift (from `https://github.com/realm/realm-cocoa.git`, branch `swift-2.0`)` required by `Podfile`
  </code></pre>
  
  <p>The Podfile looks well formed to me. I'd appreciate any help.</p>
