Über die Autorin bzw. den Autor
BJ Miller is an iOS developer for DXY Solutions, a mobile, web, and design 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 encompassed 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 in paired-programming style. BJ often presents iOS-related topics at CocoaHeads and also speaks at other conferences such as MacTech, 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.
