Hi Ben,

I have both in my app, both presenting from rootVC and just plain controller. I fish out the rootVC to get rid of warning like this "Presenting view controllers on detached view controllers is discouraged".

I am seeing crash logs from both instance of presenting view controllers (both from rootVC and not), so that's probably not the issue here.

Is there a particular reason why you are fishing out the root view controller via the delegate singleton? Does it work properly if your LeftMenuViewController instance (the class which according to your trace is making the call) simply calls presentViewController on itself instead?
