> Just like with today's iPhone, you couldn't write programs on the device itself. Tell that to the developers of Swift Playgrounds, Codea, Pythonista, Continuous, Hopscotch, Scratch Jr, Pyonkee, and plenty of other apps. (Yes, I am aware that one can do a lot less with these than native development with Xcode, but that "less" is still non-zero. In the case of apps like Codea or Pythonista, a few now-native iOS games started life in those apps because they expose quite a lot of the native frameworks to the user.)
