Inspired by using Playground-Driven Development, we’ll share our experience of applying this methodology to commercial development on iOS platform. One year ago, we in Mamba team gathered every duct tape we knew and ran away with them through the field full of pitfalls, towards a better tomorrow, where you could debug mobile apps while coding it. After making sure PDD is able to live, we decided to take a risk and to start developing our company’s key service according to this methodology. This talk aims to tell you how it was done, what results we got, how to repeat it without leaving your home. The talk will be useful for iOS developers of all levels.
