Get valuable hands-on experience with Swift 3, the latest version of Apple's programming language. With this practical guide, skilled programmers with little or no knowledge of Apple development will learn how to code with Swift 3 by developing three complete, tightly linked versions of the Notes application for the OS X, iOS, and watchOS platforms.
In the process, you'll learn Swift's fundamentals, including its syntax and features, along with the basics of the Cocoa, CocoaTouch, and WatchKit frameworks. This book teaches you how to use common design patterns for Swift, how to structure an application for Apple's platforms, and how to submit working apps to the App Store.
Divided into four distinct parts, this book includes:
Swift 2 basics: Learn Swift's basic building blocks and features for object-oriented development
OS X app development: Set up the document model, build out features, and sync data with iCloud
iOS app development: Use multimedia, contacts, location, notifications, and iCloud files to build a fully featured iOS Notes app
Advanced app extensions: Build an Apple Watch app, and learn how to debug, monitor, and test all three of your Swift apps
Actually, the book is not as much about Swift, as it is about development of applications for OS X, iOS and iWatch. If you're interested in application development, the different APIs and seeing all that integrated into a single example application, this might be a good book for you.
On the other hand, if you're interested in Swift as the language, look elsewhere. The language is covered very informally and by examples, without really explaining why things are the way they are, or going beyong the most basic use cases.
