Programming in Sw ift is a concise, carefully written tutorial on the Swift language and its use in developing iOS and OS X applications. The book makes no assumptions about prior experience with programming languages, or with Swift's precursor, Objective-C. Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Swift programming. Readers can also learn the concepts of contemporary object-oriented programming without having to first learn all of the intricacies of a procedural language like C. This approach, combined with many small program examples and exercises at the end of each chapter, makes it ideally suited for either classroom use or self-study.
