Conventions used

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

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Let's start by creating a new SwiftUI app called StaticList."

A block of code is set as follows:

struct Todo: Identifiable {
    let id = UUID()
    let description: String
    var done: Bool
}

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

struct ContentView: View {
    @State private var tabSelected = 0
...
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Tap on the + button a few times and then on the Refresh button."
