This book assumes no knowledge of the Swift programming language or any other language. All code examples have been tested using Xcode 12.01 on a Mac, however they should work using Swift on Linux or Windows as well.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example; "Once the grade is retrieved, we will use it to set the grade property of the MyValueType instance."

A block of code is set as follows:

protocol Occupation {
    var occupationName: String { get set } 
    var yearlySalary:Double { get set }
    var experienceYears: Double { get set }
}

Any command-line input or output is written as follows:

./swift/utils/build-script --preset=buildbot_swiftpm_linux_platform,tools=RA,stdlib=RA

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. For example: "Swift is a programming language that was introduced by Apple at the Worldwide Developers Conference (WWDC) in 2014."
