How do I create a page in Swift?

To create a page in Swift using SwiftUI, you can start by defining a view. Views are the basic building blocks of user interfaces in SwiftUI. Here’s a simple example to get you started:

Define a View: In SwiftUI, you describe what view you want in your user interface, and SwiftUI produces the result. Views are expressed declaratively.
Use a Scene: An app in SwiftUI is a declarative structure defined by scenes. A WindowGroup is one kind of scene that is created with a content view to show on screen.

Here’s a basic example of creating a page in SwiftUI:

import SwiftUI

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, World!")
                .font(.largeTitle)
                .padding()
            Spacer()
        }
    }
}

In this example:

MyApp is the main entry point of the app.
WindowGroup is used to create a window with ContentView as its content.
ContentView is a simple view that contains a vertical stack (VStack) with a text element.

For more advanced usage, you can explore additional capabilities such as navigation, split views, and customizable layouts. SwiftUI also allows for low-level control to create unique custom experiences, including custom control styles, high-performance drawing with canvas, and even custom metal shaders.

For a more detailed explanation, you can refer to the SwiftUI essentials session from WWDC 2024, which covers the fundamentals of views and how to build user interfaces in SwiftUI.
