如何将文本放置在ZStack SwiftUI中图像的精确点

import SwiftUI

struct ContentView: View {
    var body: some View {
        ZStack {
            Image("exampleImage")
                .resizable()
                .aspectRatio(contentMode: .fit)
                .overlay(
                    Text("Hello, World!")
                        .font(.title)
                        .foregroundColor(.white)
                        .alignmentGuide(.horizontalAlignmentGuide) { d in d[.leading] }
                        .alignmentGuide(.verticalAlignmentGuide) { d in d[.top] }
                )
        }
    }
}

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