UINavigationController pushViewController not working - ios

Question

I have a double-tap gesture on a view controller iRpImageViewerViewController (topmost on the navigation stack), and each time a view on iRpImageViewerViewController is double-tapped, it pushes a image editor view controller iRpImageEditorViewController onto the stack, that's why there are several of them, none of which appeared. Each time I double-tap, it's added, but never appears. self is simply the class that houses this double-tap gesture iRpImageViewerViewController, and does in fact have a navigationController per the LLDB output
po self.navigationController returns a navigation controller as expected.
po self.navigationController viewControllers shows a new view controller being added to the list with each pushViewController statement encountered, yet the pushed item won't show up on screen.
I shouldn't have to push and then move to front, right?? Doesn't the push automatically make it the frontmost view controller?
Note that my navigation controller is NOT the root controller in my hierarchy, starting from the window. I have a full screen map view controller, then a half-screen 'dashboard' view controller, then within that I have a window on the dashboard that has a picture, and that picture is itself a view controller. So starting with the picture view controller, shown here, you can walk through everything that happens
