I agree with the poster you're replying to - the naming is not intuitive or approachable without that previous body of knowledge. It's enough that I would call it bad - I would flag the crap out of it in a code review. I'm glad you linked to the style guide - i've often wondered where certain names come from. It's not all bad. K for key, V for value, i for index... no disagreement. But the seeming aversion to any variable name longer than 2-3 characters might be great in mathematics, but makes for a nightmare of code which is focused more on writing. It doesn't need to go the extreme of UIMutableUserNotificationAction; but at least use words. AI is already clever enough; it doesn't need to be made more cryptic with poor naming conventions. I get that for people in the industry it may be fine - but for it to break out into general use it'll need to be more social; which means simpler & clearer verbage.
