如何使用UINavigationController的searchController属性将UISearchController合并到SwiftUI NavigationView中？

struct SearchControllerWrapper: UIViewControllerRepresentable {
    @Binding var searchText: String
    
    func makeUIViewController(context: Context) -> UIViewController {
        let searchController = UISearchController(searchResultsController: nil)
        searchController.searchBar.delegate = context.coordinator
        return UIViewController()
    }
    
    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        // 更新搜索文本
        if let controller = uiViewController.parent?.navigationController {
            controller.navigationItem.searchController?.searchBar.text = searchText
        }
    }
    
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
    
    class Coordinator: NSObject, UISearchBarDelegate {
        let parent: SearchControllerWrapper
        
        init(_ parent: SearchControllerWrapper) {
            self.parent = parent
        }
        
        func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
            parent.searchText = searchText
        }
    }
}

struct ContentView: View {
    @State private var searchText = ""
    
    var body: some View {
        NavigationView {
            List {
                // 列表内容
            }
            .navigationBarTitle("Search")
            .navigationBarSearch($searchText)
        }
    }
}

extension View {
    func navigationBarSearch(_ searchText: Binding<String>) -> some View {
        overlay(SearchControllerWrapper(searchText: searchText).frame(width: 0, height: 0))
    }
}
