Swift started out by piggybacking on facilities provided by Foundation. Over time it’s becoming self-sufficient, but it’s a work in progress. Putting “design intent” in the past tense is inaccurate … I would say that this seems to be something to come in the future.

Are you asking how to use KVO with Swift arrays, or are you looking at pure Swift?
