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: “He is very thorough as well, and you can find his work at jdgauchat.com.”

A block of code is set as follows:

struct ContentView: View {
    var body: some View {
        HStack {
            Text(“Hello”)
            Spacer()

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 {
   var body: some View {
       VStack(alignment: .leading)  {
      Text(“Hi, I’m child one in this vertical stack”)
      Text(“Hi, I’m child two in this vertical stack”)

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: “We will be using the first option, which is Create a new Xcode project, for all of our projects, so select that.”
