Playing safely in Swift PlaygroundsIf you can set aside the hype, there's an amazing amount of promise for Swift Playgrounds.
I almost missed it.
I was so put off by the app's WWDC Keynote introduction and "Learn to Code" content — the hype, the marketing, and the sample content that favored gameification over pedagogy — I almost missed how good Swift Playgrounds is today and how great it can and will be in the near future.

I loved Xcode Playgrounds from the moment they were introduced two years ago: They're a perfect way to learn and experiment with Swift code.
Before Xcode Playgrounds existed, if I wanted to teach you to program, we'd have to open Xcode and create a new Single View project. We would look in the App Delegate and look for the method that was called after the app loaded. If you're new to iOS, this is where the questions start: "What's an App Delegate?", "How and when does this method get called?", et cetera, et cetera. It's a lot of cognitive overhead, and we haven't even star...
