    var body: some View {
        VStack {
            DatePicker("", selection: $selectedDate, in: currentDate..., displayedComponents: [.year, .month])
               .labelsHidden()
            Button("重置") {
                selectedDate = currentDate
            }
        }
       .padding()
    }
}

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