title: IOS app size doubled after updating frameworks that enable bitcode
body: <p>In the last month I uploaded two Builds for TestFlight. On ItunesConnect, one has a size of 63MB, while the other is 160MB! To make it worse: It shows 195MB on TestFlight, and regarding other posts, it will be double the size on the App Store!</p>
  
  <p><strong>Frameworks / libraries I use:</strong></p>
  
  <ul>
  <li>Facebook SDK: I Inlcude FBSDKCoreKit and FBSDKLoginKit. (Just drag and drop the <code>.framework</code> items into the project.</li>
  <li>Alamofire, both versions contained the swift 2.0 pre-release branch (Xcode 7 was still in beta). I Included this by drag and drop the <code>.xcodeproj</code> into my app. </li>
  <li>Google Cloud Messeging, downloaded via CocoaPods.</li>
  </ul>
  
  <p><code>regarding changes:</code> </p>
  
  <ul>
  <li>I updated the FacebookSDK to the latest SDK (v4.6.0). To check if this was the issue, I included the old SDK again, and check the file size, but that did not make any difference.</li>
  <li>I updated Alamofire, included the offcial release through cocoapods. Including via cocoapods increases the file size by 17MB so I switched back to including the <code>.xcodeproj</code> in my project.</li>
  </ul>
  
  <p><code>Regarding code:</code> Nothing big, just bug fixes.</p>
  
  <p>I have bitcode disabled for my app because GCM doesn't support this yet, it is supported for the Facebook SDK and Alamofire.</p>
  
  <p>I'm really wondering why the file size changed so dramatically. It is probably something around the release of Xcode 7, because the lower file size version was published while using Xcode 7 beta.</p>
  
  <p>On Itunes Connect, it says: <code>Supported Architectures: armv7, arm64</code> and <code>Required Capabilities armv7</code></p>
  
  <p>Is it a good thing to send a 32bit version of the app? Will this reduce file size? Will it reject my app?</p>
  
  <p>Any ideas?</p>
