With Swift, Apple has not only created a state-of-the-art programming language: it has attracted a new class of programmer that has long resisted Objective-C, its previous language. Now, with the announcement that Swift 2.0 will be open source, Swift development will expand beyond iOS to Linux, Windows, and Android. Moreover, Swift 2.0 includes many powerful new language features and refinements. While most early Swift books focused on helping the Objective-C coder moving to Swift,<b>Swift for Beginners: Develop and Design </b>took a different approach, writing for the coder who is not an Apple developer but with of Swift now could build OS X and iOS apps. Author Boisy Pitre found an eager audience: the first edition of his book became the year's #1 selling Swift programming book on BookScan, and regularly reaches #1 on Amazon's ranking of Swift best-sellers. Now, Pitre has thoroughly updated his book to reflect all of Swift 2.0's key improvements, helping new Swift programming become proficient more quickly than ever, no matter what devices or platforms they intend to target.
