BJ Miller is an iOS developer for a consultancy in the Cleveland, Ohio, area. BJ earned his B.S. in Computer Science from Baldwin-Wallace College (now called Baldwin-Wallace University) in Berea, Ohio, the town where he grew up. His latest career path encompasses large-scale enterprise network administration, SQL database administration, and Microsoft SharePoint Server and Microsoft Project Server administration and integration as a contractor for the United States Department of Defense, with all the Microsoft certifications that come along with that. Before that, he spent several years in LAN engineering, designing and implementing network infrastructure, as a Cisco Certified Network Associate.

BJ began iOS development in 2009 after not having programmed for a few years, and he developed a passion for the platform and the Objective-C language. Now, his love has expanded to include Swift, and there is still yet room in his heart for more. In 2013 he released his first app into the iOS App Store, called MyPrayerMap, as a simple tool for managing prayer requests.

When he is not writing in Objective-C or Swift for either work or this book, he enjoys spending time with his wife and two boys, reading, listening to music or podcasts, and playing The Legend of Zelda (any game on any system will do). He also co-organizes the Cleveland CocoaHeads Meetup with Daniel Steinberg, http://www.meetup.com/Cleveland-CocoaHeads/, and organizes a submeetup of that group called Paired Programming Fun, which is a casual meetup where the focus is on Test-Driven Development (TDD) in Swift and Objective-C in paired-programming style. BJ often presents iOS-related topics at CocoaHeads and also speaks at other conferences such as CocoaConf (Columbus, Ohio) and CodeMash v2.0.1.5. He also blogs from time to time at http://bjmiller.me and is on Twitter as @bjmillerltd.

This book is dedicated to my wonderful family and friends who have been incredibly supportive throughout this entire process. Thank you all for your love and encouragement.

I would like to thank my wife and two boys for putting up with me while I wrote this book. I am excited to spend more time with you. I would also like to thank whoever invented coffee; may the Lord bless your soul and keep you. Speaking of the Lord, it is pretty close to not humanly possible that this book would have been completed in time, with all the other obstacles going on in my life, without his loving arms around me and my family; thank you, Jesus.

I would also like to thank my friends, coworkers, and the rest of the Mac/iOS community for all their love and encouragement. If I had not been introduced to someone, who introduced me to someone, who introduced me to Daniel Steinberg, I might not have pursued iOS development further and I might not have written this book. If you ever get the chance to meet that man, your life will be enriched.

Also, I cannot go without thanking the fine people who helped this book come to be: Trina MacDonald (Acquisitions Editor), Chris Zahn (Senior Development Editor), Olivia Basegio (Editorial Assistant), Hank Turowski (Technical Editor), Geneil Breeze (Copy Editor), and Betsy Gratner (Project Editor).
