<p><b>ROB NAPIER</b> has been developing iPhone applications for as long as there has been an iPhone platform. Before coming to Cocoa development, he made his living sneaking into Chinese facilities in broad daylight. He now is a Mac developer for Dell. It’s not clear which was the stranger choice of career. He has passion for the fiddly bits below the surface, like networking, performance, security, and correct use of the MVC pattern. He muses on technical topics at Cocoaphony (cocoaphony.net).</p> <p><b>MUGUNTH KUMAR</b> is an independent iOS developer based in Singapore. He holds a master’s degree from Nanyang Technological University. His core areas of interest include human-computer interaction and usability engineering. He writes in-depth articles covering iOS programming and the user experienced at blog.mugunthkumar.com</p>

<p><b>WHY SETTLE FOR GOOD MOBILE APPS WHEN YOU CAN BUILD EXTRAORDINARY ONES?</b></p> <p>iOS is the hottest development platform around, and now iOS 6 adds a new, deeper dimension to explore.
