ChatGPT has been a godsend for helping me figure out how to use quite a few Mac and iOS APIs in the last year. There are APIs that would’ve taken me an hour or more to work out how to use by searching online, experimenting, digging up old WWDC videos (often the only place to really learn how to use a given API properly), but now it takes seconds of ChatGPT. It’s been a game-changer.
