I am looking for a good app that teaches my nine year old grandson to code---preferrably on the iPad which allows him to make simple iPad/iPhone apps. I came across an evaluation of Swift Playgrounds, which looks promising. The article claimed that Swift Playgrounds came preloaded on my iPad Pro, so I tried to do a search. That led to a problem and my second question. When I type in a search topic I get a lot of references to iTunes, the app store, and the web---absolutely none to files on my iPad. (I tried inputting apps I know to be on my iPad, but they didn't come up in search results either.) Can anyone help?
