Steven F. Daniel - Xcode 4 cookbook

No book is the product of just the authorhe just happens to be the one with his name on the cover. A number of people contributed to the success of this book, and it would take more space if I have to thank each one individually.

A special shout-out goes to Mary Nadar, my acquisition editor, who is the reason that this book exists. Thank you Mary for believing in me and for being a wonderful guide throughout this whole process. I would like to thank Amey Sawant for ensuring that I stayed on track and got my chapters in on time, and to Dayan Hyames for his brilliant suggestive approach with the chapter rewrites.

I would also like to extend my thanks to each of my Technical Editors for their brilliant suggestions and improvements to each chapter, as well as ensuring that we met our timeframes, and delivery for this book. It has been a great privilege to work with each of you on this book.

Lastly, to my reviewers, thank you so much for your valued suggestions and improvements, making this book what it is. I am grateful to each and every one of you.

Thank you also to the entire Packt Publishing team for working so diligently to help bring out a high quality product. Finally, a big thank you to the engineers at Apple for creating the iPhone and the iPad, and providing developers with the tools to create fun and sophisticated applications. You guys rock.

Finally, I'd like to thank all of my friends for their support, understanding, and encouragement during the writing process. It is a privilege to know each and every one of you.

Robert Wohnoutka is an independent software developer with over 20 years of software development experience. He currently has 11 iPhone apps in the Apple app store.

Robert is a former Apple employee where he learned the importance of ease-of-use which is the first rule he applies in all the apps that he develops. He also has over 20 years of Product Marketing experience with high-tech products where the ease-of-use aspect was his guiding light as he helped companies develop and introduce new technologies into the hands of consumers.

My Walks is a good example of an app Robert developed where he applied the ease-of-use principal to a GPS-based walking application. This app only requires the user to tap a Start button to start the walk and the app will automatically detect the end of the user's walk should the user forget to tap the End button. My Walks was featured in the Best Mobile Apps 2013 book by Jeremy J. Warner and published by Portrait Health Publishing Inc. Robert has also developed a version for bicycling named My Bike Rides and a version for skiing named My Ski Runs.
