SwiftUI -如何重新绑定绑定的可选参数？

struct ContentView: View {
    @State private var isShowingDetail = false
    
    var body: some View {
        VStack {
            Button("Show Detail") {
                isShowingDetail.toggle()
            }
            
            if isShowingDetail {
                DetailView(isShowingDetail: $isShowingDetail)
            }
        }
    }
}

struct DetailView: View {
    @Binding var isShowingDetail: Bool
    
    var body: some View {
        VStack {
            Text("Detail View")
            
            Button("Hide Detail") {
                isShowingDetail = false
            }
        }
    }
}
