使一个视图与在SwiftUI中具有动态大小的另一个视图大小相同

import SwiftUI

struct ContentView: View {
    var body: some View {
        GeometryReader { geometry in
            VStack {
                // 目标视图，它的大小是动态的
                DynamicSizeView()
                    .frame(width: geometry.size.width / 2, height: geometry.size.height / 2)
                
                // 要与目标视图大小相同的视图
                SameSizeView()
                    .frame(width: geometry.size.width / 2, height: geometry.size.height / 2)
            }
        }
    }
}

struct DynamicSizeView: View {
    var body: some View {
        Text("我是动态大小的视图")
            .padding()
            .background(Color.blue)
            .cornerRadius(10)
    }
}

struct SameSizeView: View {
    var body: some View {
        Text("我与上面的视图大小相同")
            .padding()
            .background(Color.red)
            .cornerRadius(10)
    }
}

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