I've been using Interface Builder almost exclusively ever since Apple introduced autolayout for iOS.
I recently came across SnapKit but I don't see any immediate advantage this has over using constraints in IB. The only thing it's got going for it is resolving merge conflicts in a larger team (merge conflicts in IB are a pain to deal with).
Does anyone, who has used both SnapKit and IB, know why SnapKit would be preferable?
