I could throw up Dates and Dictionaries over the weekend. There's a Playground switch so you can copy-paste the text as a working Playground:

I'm very pleased that these resources are coming into being for people wanting to get started in programming and for Swift specifically. The Stanford course is great but too high-level for a lot of people. I have put up projects myself with pre-built modules to hopefully make it easier for people to get started - https://github.com/timburgess/ScienceKit
2. How the hell is this an iOS app?
2) Not actually running any (of your) code, or coding really. Tap this to fill in a string, or to select an operator from a few approved.
That being said, I'm kind of impressed someone managed to get an app on the App Store that can do this. I know that Apple loosened its restrictions on code execution on iOS a while back, but as far as I am aware there's no way to compile Swift on ARM… did they write their own compiler/runtime or something?
