title: Crash with "Symbol not found: _OBJC_CLASS_$_NSMutableURLRequest"
body: <p>I have installed my app from Xcode 5.1.1 in debug mode on iPad 3 with iOS 7.1.1, as show below in crash log. In day of installing app was working fine. I was not using my iPad for 2 days and today it just crashes on Splash screen, at first second. Restart of iOS does not helped.</p>
  
  <p>Any ideas why it could happening? I will re-add CFNetwork and Foundation frameworks to my project, just in case, but maybe it's something other? Could be it a bug in iOS? </p>
