如何让SwiftUI响应不同的设备？(Swift)

import SwiftUI

struct ContentView: View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
                Text("Hello, SwiftUI!")
                    .font(.largeTitle)
                    .frame(width: geometry.size.width / 2)
                    .background(Color.green)
                    .cornerRadius(20)
            }
        }
    }
}

import SwiftUI

struct ContentView: View {
    @Environment(\.horizontalSizeClass) var sizeClass
    
    var body: some View {
        VStack {
            if sizeClass == .compact {
                CompactView()
            } else {
                RegularView()
            }
        }
    }
}

struct CompactView: View {
    var body: some View {
        Text("Compact View")
    }
}

struct RegularView: View {
    var body: some View {
        Text("Regular View")
    }
}

import SwiftUI

extension View {
    func deviceSpecificModifier() -> some View {
        if UIDevice.current.userInterfaceIdiom == .phone {
            return self.padding(.all, 10)
        } else {
            return self.padding(.all, 20)
        }
    }
}

struct ContentView: View {
    var body: some View {
        Text("Hello, SwiftUI!")
            .deviceSpecificModifier()
    }
}
