I used ChatGPT recently to develop an iOS app (I'm an iOS dev, but I wasn't proficient with SwiftUI at the time). ChatGPT astounded me. When I copied something that didn't work, I could tell it "hey I get this error" and it would reply with the necessary changes. I was able to get an MVP together this way. I learn by doing and I learnt much more quickly using this method than reading guides/watching YouTube/reading docs. Until that point I didn't fully get the AI craze.
