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.

When mentioning pieces of code in text we will use the style as follows: "You can see that "Hello, playground" was indeed stored in the variable.

If the code is longer it will presented as a block as follows:

if invitees.count > 20 {
   println("Too many people invited")
}
else if invitees.count <= 3 {
    println("Not really a party")
}
else {
    println("Just right")
}

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: "Now, click on Connect on the Remote Desktop Viewer". Keyboard shortcuts will be displayed using the key style.
