在SwiftUI `DatePicker`中点击日期时如何抓取？

import SwiftUI

struct ContentView: View {
    @State private var selectedDate = Date()
    
    var body: some View {
        VStack {
            Text("Selected Date: \(selectedDate)")
            
            DatePicker(
                selection: $selectedDate,
                displayedComponents: .date,
                label: { Text("Select a date") }
            )
            .onTapGesture {
                // 在这里处理日期点击事件
                print("Date tapped!")
            }
        }
    }
}

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