Does a navigation bar ever require constraints?

So far, I have two distinct uses of a navigation bar in my app: one produced by a Navigation Controller with a View Controller embedded in it and one added manually from the Object Library into a different View Controller presented modally (since a modally presented view apparently doesn't inherit the navigation controller of the view under it).

My question: do either of these navigation bars require constraints?

Yes, the one added by you, as it is managed by you. The other one is managed by UINavigationController. Also it wouldn't make sense for a modal controller to have the navigation bar of its presenter - you are showing an "extra" screen, not navigating the hierarchy. It is also worth mentioning that nothing stops you from presenting another UINavigationController modally with a separate navigation flow.
