Acknowledgments

I would like to thank all the developers and Apple engineers on the Apple Developer Forums who shared information and insights leading up to the release of iOS 5. When working with brand new technologies, we don’t have an established set of best practices to fall back on, so it was great to have such an active group with whom I could discuss the ins and outs of all the new features of iOS 5. By pooling our experiences, we pieced together a number of tips, tricks, hints, and clues—many of which found their way into this book.

Additionally, this book would not have been possible without a lot of hard work from many extremely talented people. Many thanks to Scout Festa for the copyediting and for otherwise bringing out the real meaning behind my words. To Shaun Austin for all the technical editing and advice. To the production team—Katerina Malone, Danielle Foster, and Rebecca Plunkett—and everyone else at Peachpit Press, who performed minor miracles of magic with the layout and design, as well as a hundred other tasks that I can barely imagine or even understand.

Finally, a big thanks to my editors, Dan Foster and Clifford Colby, for riding herd over all of us. It has been a long and often twisty road. I am glad we stuck with it and saw it to the end.
