Pythonista is really very good, and it is easy to pip install pure Python libraries. Too bad Python is not one of my favorite languages. The Raskell app used to provide a decent Haskell environment in iOS, but, file access stopped working. Really too bad since it was fun to hack Haskell on airplanes, etc. Swift Playgrounds on iOS are very interesting and makes me wonder if XCode might someday live in iOS, with appropriate code sandboxing. Apple has made iOS and macOS app development much simpler with SwiftUI, simple enough that I enjoy using it. I think Apple will jump through hoops in the coming years to make app development easier.
