Erica Sadun is an expert in all things related to iOS. She holds a Ph.D. in computer science from Georgia Tech's Graphics, Visualization and Usability Center, did early development work in Objective-C, has written many books about iOS development, and has recently embraced Apple's Swift language, culminating in her latest book: the "Swift Developer's Cookbook." I've had the pleasure of meeting Erica many times, back when she had time to manage the Denver Apple Geek lunches. Erica presented me with some intriguing ideas about the state of Apple, iOS, and Apple's product line imagination. Your Apple thinking will be challenged in this candid interview.
