Tinker … Learn

This is really cool. Given that I have been thinking about developing an iOS app for field researchers, the timing on this could not have been better: [TinkerLearn](https://www.tinkerlearn.com/xray) aims to teach you iOS development by showing you a real app and walking you through its source code. What you get is an Xcode project with lots and lots of comments. You can run it yourself and then see what works and what doesn’t work.

If we taught writing the way programming is often taught, we would never have students read any kind of writing before asking them to write themselves, which is somewhat nonsensical. The way we learn so much of what we learn is through mimicry, mimicry leads competency, and, with desire and discipline, competency can lead to mastery.

And I love the logo:
