terminate called after throwing an instance of 'NSException'

Answer 1

Well I don't know what you want us to tell you more then your error is already telling you.
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: '-[UIViewController
_loadViewFromNibNamed:bundle:] loaded the "RootViewController" nib but
the view outlet was not set.'
That is that you forgot to connect your view outlet of your RootViewController so it does not know what to load. The RootViewController of your MainWindow is the first thing that's going to be loaded, if it does not know what view it should display it will give you the above error.
