The Scope of This Book

This book is actually one of a pair with my Programming iOS 12, which picks up exactly where this book leaves off. They complement and supplement one another. The two-book architecture should, I believe, render the size and scope of each book tractable for readers. Together, they provide a complete grounding in the knowledge needed to begin writing iOS apps; thus, when you do start writing iOS apps, you’ll have a solid and rigorous understanding of what you are doing and where you are heading. If writing an iOS program is like building a house of bricks, this book teaches you what a brick is and how to handle it, while Programming iOS 12 hands you some actual bricks and tells you how to assemble them.

When you have read this book, you’ll know about Swift, Xcode, and the underpin‐ nings of the Cocoa framework, and you will be ready to proceed directly to Program‐ ming iOS 12. Conversely, Programming iOS 12 assumes a knowledge of this book; it begins, like Homer’s Iliad, in the middle of the story, with the reader jumping with all four feet into views and view controllers, and with a knowledge of the language and the Xcode IDE already presupposed. If you started reading Programming iOS 12 and wondered about such unexplained matters as Swift language basics, the UIApplicationMain function, the nib-loading mechanism, Cocoa patterns of delega‐ tion and notification, and retain cycles, wonder no longer — I didn’t explain them there because I do explain them here.

The three parts of this book teach the underlying basis of all iOS programming:

Part I introduces the Swift language, from the ground up — I do not assume that you know any other programming languages. My way of teaching Swift is differ‐ ent from other treatments, such as Apple’s; it is systematic and Euclidean, with pedagogical building blocks piled on one another in what I regard as the most helpful order. At the same time, I have tried to confine myself to the essentials. Swift is not a big language, but it has some subtle and unusual corners. You don’t need to dive deep into all of these, and my discussion will leave many of them unexplored. You will probably never encounter them, and if you do, you will have entered an advanced Swift world outside the scope of this discussion. To give an obvious example, readers may be surprised to find that I never mention Swift playgrounds or the REPL. My focus here is real-life iOS programming, and my explanation of Swift therefore concentrates on those common, practical aspects of the language that, in my experience, actually come into play in the course of programming iOS.

Part II turns to Xcode, the world in which all iOS programming ultimately takes place. It explains what an Xcode project is and how it is transformed into an app, and how to work comfortably and nimbly with Xcode to consult the documenta‐ tion and to write, navigate, and debug code, as well as how to bring your app through the subsequent stages of running on a device and submission to the App Store. There is also a very important chapter on nibs and the nib editor (Interface Builder), including outlets and actions as well as the mechanics of nib loading; however, such specialized topics as autolayout constraints in the nib are post‐ poned to the other book.

Part III introduces the Cocoa Touch framework. When you program for iOS, you take advantage of a suite of frameworks provided by Apple. These frameworks, taken together, constitute Cocoa; the brand of Cocoa that provides the API for programming iOS is Cocoa Touch. Your code will ultimately be almost entirely about communicating with Cocoa. The Cocoa Touch frameworks provide the underlying functionality that any iOS app needs to have. But to use a framework, you have to think the way the framework thinks, put your code where the frame‐ work expects it, and fulfill many obligations imposed on you by the framework. To make things even more interesting, Cocoa uses Objective-C, while you’ll be using Swift: you need to know how your Swift code will interface with Cocoa’s features and behaviors. Cocoa provides important foundational classes and adds linguistic and architectural devices such as categories, protocols, delegation, and notifications, as well as the pervasive responsibilities of memory management. Key–value coding and key–value observing are also discussed here.

The reader of this book will thus get a thorough grounding in the fundamental knowledge and techniques that any good iOS programmer needs. The book itself doesn’t show how to write any particularly interesting iOS apps, but it does constantly use my own real apps and real programming situations to illustrate and motivate its explanations. And then you’ll be ready for Programming iOS 12, of course!
