How can I present Navigation and Tab bar using 3D Touch
The same way you do it during the normal run of your app. You should not be doing some special thing in response to the user pressing the shortcut item (i.e. your self.window?.rootViewController?.present, which in effect merely puts up a temporary facade); you should be navigating to the actual area of your real app that the shortcut item corresponds to.
