如何将内容视图缩放到多个屏幕大小？SwiftUI

import SwiftUI

struct ContentView: View {
    @Environment(\.horizontalSizeClass) var horizontalSizeClass
    @Environment(\.verticalSizeClass) var verticalSizeClass
    
    var body: some View {
        GeometryReader { geometry in
            VStack {
                if horizontalSizeClass == .compact && verticalSizeClass == .regular {
                    Text("手机竖屏布局")
                        .font(.largeTitle)
                } else {
                    Text("平板或横屏布局")
                        .font(.largeTitle)
                }
                
                Spacer()
                
                Text("屏幕宽度: \(geometry.size.width)")
                Text("屏幕高度: \(geometry.size.height)")
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
