Swift UI - HostingController添加了不需要的导航栏

import SwiftUI

// 创建一个Swift UI视图
struct ContentView: View {
    var body: some View {
        Text("Hello, World!")
    }
}

// 在UIKit或AppKit应用程序中使用HostingController
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建HostingController实例并设置导航栏隐藏
        let hostingController = UIHostingController(rootView: ContentView().navigationBarHidden(true))
        
        // 将HostingController添加到视图层次结构中
        addChild(hostingController)
        view.addSubview(hostingController.view)
        hostingController.view.translatesAutoresizingMaskIntoConstraints = false
        hostingController.view.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
        hostingController.view.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
        hostingController.view.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
        hostingController.view.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
        hostingController.didMove(toParent: self)
    }
}
