如何在SwiftUI中把图片按钮放在圆形图片的边角下？

struct ContentView: View {
    var body: some View {
        ZStack {
            Image("circleImage")
                .resizable()
                .aspectRatio(contentMode: .fit)
                .clipShape(Circle())
            
            Button(action: {
                // 按钮点击事件
            }) {
                Image(systemName: "heart.fill")
                    .foregroundColor(.red)
                    .padding()
            }
            .background(Color.white)
            .clipShape(Circle())
            .alignmentGuide(HorizontalAlignment.trailing, computeValue: { dimension in
                dimension.width / 2
            })
            .alignmentGuide(VerticalAlignment.top, computeValue: { dimension in
                -dimension.height / 2
            })
        }
    }
}
