Storyboards are a powerful yet oft maligned tool for controlling the flow of your iOS app through configuration instead of code.

The storyboard approach in theory allows a clean separation of flow and presentation that provides greater flexibility to change. The reality though is that view controller code typically ends up becoming deeply entwined with the storyboard itself, leading to inflexible, oft duplicated code. 

This approach can leave many an experienced developer wondering "is it worth it?" and becoming wary of its use. In this session we take a fresh cut - we pick up the story where other 'architecture' approaches don't tread and learn about a powerful approach to maintaining the separation of storyboard from view controller that delivers on the promise of flexibility and less configuration in code.

    Trying to better understand the problems of the Internet of Things by actually listening to its detractors. There's a lot of valid criticism of the Internet of Things, generally under the catchy phase 'The Internet of Shit'.

    This talk is a light-hearted look at the problems of existing IoT devices, and how to be constructive by transforming criticisms into requirements for a better Internet of Things. And we'll look at some of the proposed solutions for better ways to do IoT.
