Presenting new views using sheets

SwiftUI's sheets are used to present new views over existing ones while allowing the user to dismiss the new view by dragging it down.

In this recipe, we will learn how to present a sheet to the user and add navigation items to the sheet.

Getting ready

Create a new SwiftUI project named PresentingSheets.

How to do it

We shall create two SwiftUI views named SheetView and SheetWithNavView that will be displayed modally when a button is clicked. The steps are as follows:

1. In ContentView.swift, between the struct declaration and the body variable, add two state variables, showSheet and sheetWithNav. The state variables will be used to trigger the sheet presentation:

   @State private var showSheet = false
   @State private var sheetWithNav = false;

2. Add a VStack and a Button that changes the value of our showSheet variable to true when clicked. Add a .sheet() modifier to the button that gets displayed when showSheet is set to true...
