If you are confused about the NSAutoresizingMaskLayoutConstraints in that list, it might be because you haven't called setTranslatesAutoresizingMasksIntoContraints(false) on that view. (although, I was under the impression that SnapKit does that for you).

If you are confused about the NSIBPrototypingLayoutConstraint, that's an auto-generated constraint by Interface Builder. To get rid of it, add some Top, Bottom, Leading and Trailing constraints in Interface Builder and set them to be removed at build time.
