How do I structure a SwiftUI app with App protocol?

In SwiftUI, structuring an app using the App protocol is essential for defining the main entry point of your application. This allows for a declarative approach to building your app’s user interface. Here’s a simple example of how to set up a SwiftUI app with the App protocol:


        import SwiftUI
        
        @main
        struct MyApp: App {
            var body: some Scene {
                WindowGroup {
                    ContentView()
                }
            }
        }
        
        struct ContentView: View {
            var body: some View {
                Text("Hello, World!")
            }
        }
