Readme This is a book about building apps with good design, parsimonious code and aesthetic appeal on the Apple iPhone and iPod Touch. At times, this book references code and give sample projects; other times, it delves into interaction and visual design. It doesn?t take a CS doctorate to appreciate or even understand, but some familiarity with programming is assumed. Who is this book for? Lots of people. Mac developers looking to do a killer iPhone app might want to know the hard-won lessons or philosophies of others; iPhone hackers looking to step up their game might be trying to figure out how much to emulate Apple. Anyone who appreciates a success story will hopefully enjoy this book, but it?s also inspirational. How technical is it? Parts of this book assumes basic knowledge of C or other object-oriented programming languages. In some cases, we reference specific Apple frameworks and interface guidelines. It will also help to be familiar with the Apple environment, from the quirks of the App Store to technologies inside OS X. How were these interviewees chosen?
