在SwiftUI中实现长方体阴影

import SwiftUI

struct ContentView: View {
    var body: some View {
        Rectangle()
            .frame(width: 200, height: 100)
            .foregroundColor(.blue)
            .cornerRadius(10)
            .shadow(color: .gray, radius: 5, x: 0, y: 0)
    }
}

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