title: App Crash with Exception Type: EXC_CRASH (SIGKILL - CODESIGNING)
body: <p>I have created a very simple app which runs fine in the iOS-Simulator.
  If I run the app with XCode on my iPad it also runs fine for a while.
  Without having the iPad connected to XCode my app is starting but if I get to a screen where is needs to load data into a UIWebview it crashes.
  If the iPad is connected to XCode or I run the app in the iOS-Simulator this won't happen.
  I have reviewed the log in the Crashreporter but I have no clue at the moment why the app crashed.
  To load the content into the webview I am using the latest AFNetworking version via Cocoapods.
  The app only crashed if you call a ViewController with a UIWebview. The Webview is trying to load the content but is grey in the background. After 10 seconds the app crashes.</p>
