In order to get the most out of this book, there are a few essentials you will need:

This book is ideal for those who want to learn how to develop apps in Swift, starting the right way. Whether you are an expert Objective-C programmer or are new to this platform, you'll quickly grasp the code for real-world apps and discover how to use Swift effectively. Prior experience in the development of Apple devices would be helpful, but it is not mandatory.

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

let mainWindow = UIWindow(frame: UIScreen.mainScreen().bounds)
mainWindow.backgroundColor = UIColor.whiteColor()
mainWindow.rootViewController = navigatorViewController
mainWindow.makeKeyAndVisible()
window = mainWindow
return true

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

let mainWindow = UIWindow(frame: UIScreen.mainScreen().bounds)
mainWindow.backgroundColor = UIColor.whiteColor()
mainWindow.rootViewController = navigatorViewController
mainWindow.makeKeyAndVisible()
window = mainWindow
return true

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Clicking the Next button moves you to the next screen."
