19.4 The ContentView.swift File

This is a SwiftUI View file that, by default, contains the content of the first screen to appear when the app starts. This file and others like it are where most of the work is performed when developing apps in SwiftUI. By default, it contains a single Text view displaying the words “Hello, world!”:

import SwiftUI

 

struct ContentView: View {

    var body: some View {

        Text("Hello, world!")

           .padding()

    }

}

 

struct ContentView_Previews: PreviewProvider {

    static var previews: some View {

        ContentView()

    }

}
