Creating a standard tab bar

Follow these steps to create a standard tab bar:

  1. We can start a new iOS project by using the usual iOS App template.
  2. Then, we can add a new view to the project and name it HomeView.
  3. To let ContentView use this HomeView view, we can substitute this view as the content of the default ContentView.
  4. Finally, we populate the HomeView.swift file with the following code.

    We start by creating five views, which will be individually switched as the content of TabView:

    import SwiftUI
    struct ViewA:
        View {
        var body: some View {
                Text("This is View 1")
                    .fontWeight(.bold)
                    .font(.title)
             ...
