You can, in fact, write an app and publish it to Apple's App Store with it, all from an iPad. I have no idea how much actual uptake this has seen, since I think the capability only came out at the start of the year?
This is probably fixed now, but around the days of Swift versions 1-3, Playgrounds were straight up broken. Very basic programs would segfault the compiler. I feel bad for any kids who may have been introduced to programming that way.
Very simple programs would segfault the compiler in 1-3 as well. You'd most often notice this as your syntax highlighting went away for a period of time.
Playgrounds is mostly a local running environment if I am right ?
If you teach a class, having a CI build and run the programs, potentially taking screenshots for you to review later could be a pretty good use case, especially for remote home work.
