如何在SwiftUI中检测点击手势的位置？

import SwiftUI

struct ContentView: View {
    @State private var tapLocation: CGPoint?

    var body: some View {
        GeometryReader { geometry in
            VStack {
                Text("Tap anywhere")
                    .font(.largeTitle)
                    .foregroundColor(.blue)
                    .background(Color.white)
                    .cornerRadius(20)
                    .gesture(
                        TapGesture()
                            .onChanged { value in
                                tapLocation = value.location
                            }
                            .onEnded { _ in
                                tapLocation = nil
                            }
                    )
                if let location = tapLocation {
                    Text("Tapped at: \(Int(location.x)), \(Int(location.y))")
                        .foregroundColor(.red)
                        .padding()
                }
            }
            .frame(width: geometry.size.width, height: geometry.size.height)
        }
    }
}

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