Cesar and Clay chat about building games for iOS with Swift. In this episode we talk about Clay’s newly released book, while also discussing the game development ecosystem, predicting the apple marketplace, the process of game making, and the practicality of creating a game development company.

Swift game development is very exciting. If it isn’t already obvious with the content of our site, we love to talk about game development. Mobile gaming is a rapidly growing market, and iOS is by far the most rewarding and exciting to build games for. If you’ve ever wanted to learn how to build an iOS game as an indie developer, we have some resources and advice for you.

Matt Mathias of Big Nerd Ranch provides some insight:

In this post, I will show you how to peek inside the .playground file to gain a sense of how a Playground is put together. Glancing at these internals will help you to create your own interactive document.

Here’s a library that allows you to very easily show directions within many popular map apps called CMMapLauncher from Citymapper.

CMMapLauncher provides a simple syntax for detecting whether a directions app is installed, and setting up those directions.

Here’s an example from the readme showing how to launch directions within the Citymapper app:

CLLocationCoordinate2D bigBen = CLLocationCoordinate2DMake(51.500755, -0.124626);
[CMMapLauncher launchMapApp:CMMapAppCitymapper
            forDirectionsTo:[CMMapPoint mapPointWithName:@"Big Ben"
