It's interesting you mention this since I just spent a bunch of time trying to get this toolbar thing working according to Apple HIG. For example, it used to say that on iPad you should put the bar button items in the Navigation Bar but on iPhone they should be at the bottom in a Toolbar. Now they say to use the Size classes to determine this. For example, regular width they put buttons in nav bar but in compact width use toolbar. This is because compact width generally corresponds to iPhone. But just to make things complicated multitasking windows on iPad are compact width. Further, landscape iPhone 6 plus (e.g. 5.5" display) is regular width. Gah! This is kind of weird because the toolbar hides and shows based on device rotation and multitasking modes, which seems a little jarring to me. But hey, go with the flow. That said, I'm looking at my code and I see that I implement this logic in traitCollectionDidChange. And I'm just using self.navigationController.toolbarHidden for toolbar hiding and it seems to work fine. See if this property works for you, and let us know. Otherwise, there might be some other code hiding the toolbar.
