This is the main "problem" with autolayout. It's an amazing experience that "just works" if you think in the way that autolayout asks you to (relativity, declarative, the idea that each dimension is fully defined by exactly two constraints, isolation of dimensions aside from aspect ratio, etc).

If you don't think that way, or you're debugging somebody else's layout, then yeah, it's a nightmare. But it's shockingly easy to just redo the whole layout in that case.
