title: ExtJS 6 app is crashing Cordova/iOS
body: <p>I'm testing an ExtJS 6 app on the latest version of iOS. I've tried three different versions of Cordova iOS platform (3.6, 3.8, and 3.9), along with two different versions of Cordova CLI (4.3, 5.1). For some reason, including certain stores or controllers in the requires section of app.js causes the app to completely crash, or to display a white screen. All of these components work just fine in the Android and web ports of our app. These problems are just happening on iOS.</p>
  
  <p>Has anyone had something like this happen? It's really odd and we're unable to debug it as the Cordova webview won't allow output to the javascript console or use of the debugger when this happens.</p>
