Hey Justin, you're something of an Mobile app expert nowadays, aren't you?

Well, I have built several significant iPhone apps for various clients over the past few years.

Do you want to do a video series on the topic?

Sure, Dad. That sounds like fun. Actually, I've been learning Swift. Do you want to do the videos using Swift?

Swift, eh? Sure, why not. I don't mind learning a new language. We can do TDD right?

Yes, the tools support TDD, no problem.

Great! OK, so let's write a simple Go-Moku app.

You mean that five-in-a-row game you play on a GO board? That sounds like fun. So what are we trying to teach in this series?

Well, I think our focus should be to use the series to teach the following principles:

  • TDD -- How to do Test Driven Development, for a mobile app, in Xcode and Swift.

  • Pairing -- You and I will pair program, and talk through our issues so that the viewers can follow along.

  • Pomodoro -- We'll use the Pomodoro time-management technique both to structure the videos, and to manage our time.

  • Model First -- We'll drive the development by building the business rules first, and then fit the GUI, network, and data access in later.

  • Clean Architecture -- We'll separate the GUI, Business rules, data access, etc. into separable components. Keeping the architecture clean.

  • Dependency Management -- Using OO, we'll create a plugin structure between those components that will allow the application to scale.

  • Swift -- And, we'll explore some of the interesting language quirks and features of Swift.

OK, so just normal, professional, mobile development. I'm on board. Sounds like a hoot. Let's go!
