View Hierarchy does not show anything

Hi.

My ViewHierarchy does not show anything - just a blank screen. I have tried different devices as simulators - iphone 5,5s,6, all with iOS 9.2. My XCode is 7.2.

I don't know what to do at this point. Thanks

Did you make sure that you have a view controller set as the initial view controller?

Hello Paul, Thanks for helping out. The initial controller is the Navigation Controller. Anything else throws an error at the line in AppDelegate.swift: let navController = window!.rootViewController as! UINavigationController

Also, the same behavior happens with the FunFacts project from the 'build a simple iphone app with swift' course , where I have the ViewController set as my Initial ViewController. (I am following the steps here: https://developer.apple.com/library/ios/recipes/xcode_help-IB_storyboard/Chapters/SetInitialController.html)

Same issue for me but I figured this was because I'm running OS X in a virtual machine at the moment. (XCode 7.3.1)
