You will need the following things for the book:

Children who are curious about the technology we use in our daily lives and who want to know how it works can use this book to learn about programming and build their first iOS app. No prior programming experience is necessary.

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: "The compiler will expect your variables to be of a certain type (int, string, and so on) and will throw a compile-time error if you try to assign a value of a different type."

A block of code is set as follows:

class Pokemon {
    let name: String
    init(name: String) {
        self.name = name
    }
}

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: "Launch Xcode and navigate to File | New | Project."
