au. Jon Manning is a world renown iOS development trainer and writer, game designer and mobile software engineering wizard. He has co-authored two books on mobile development and enjoys re-implementing such things as OpenGL and the Objective-C runtime (in his spare time). Jon is also a researcher in Human-Computer Interaction working towards a PhD. Tim Nugent pretends to be a mobile app developer, game designer, PhD student, and now he even pretends to be an author. When he isn't busy avoiding being found out as a fraud, he spends most of his time designing and creating little apps and games he won't let anyone see. Tim spent a disproportionately long time writing this tiny little bio, most of which was spent trying to stick a witty sci-fi reference in, before he simply gave up. Tim can be found as @The_McJones on Twitter.
