如何将SwiftUI视图添加到现有的选项卡栏控制器

import SwiftUI

struct MySwiftUIView: View {
    var body: some View {
        Text("Hello, SwiftUI!")
    }
}

import UIKit
import SwiftUI

class FirstViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let mySwiftUIView = MySwiftUIView()
        let hostingController = UIHostingController(rootView: mySwiftUIView)
        
        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)
    }
}
