I think it's a shame to teach kids to program on a platform as closed as iOS. A 12 year old I know wrote an app as a birthday gift for his grandfather who lived overseas. The app was simple and displayed the grandfather's age with various different effects. Unfortunately, he wrote the app for iOS and so there was no easy way to deliver the app to grandfather (the family tried to submit it to the app store but it was rejected). At least Swift Playgrounds allows kids to share with one another. Just don't try to leave the playground.
