SwiftUI:在VStack中查看阴影？

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            Text("Hello, SwiftUI!")
                .font(.largeTitle)
                .padding()
                .background(Color.blue)
                .foregroundColor(.white)
                .cornerRadius(10)
                .shadow(color: .gray, radius: 5, x: 0, y: 2)
        }
    }
}

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