I am using uikit code in SwiftUI.This approach is not metioned anywhere in apple documentation.Is this right approach?

For my use case i need to access the same intance of MyViewController ,which i am using in UIViewRepresentable for adding it to SwiftUI herierchy .And to achive that i am creating a static intance of MyViewController and using it in objective c function to make changes in viewcontroller as well as adding it in SwiftUI view hireiachy . Is this a right apprach to use ? I dont find any documentation by apple which suggest this approach .

Just want to validate it here .

And also Is this method of using UIRepresentableController right method to use in my UIkit's view controller in SwiftUI and updating viewcontroller from objectiveC ? or is there any other approach to achieve this ?

Entry Point :

import SwiftUI

@main
struct MyApp: App {
    
    var body: some Scene {
        WindowGroup {
            SwiftUIView()
        }
    }
}

SwiftUIView:

import SwiftUI

struct SwiftUIView: View {
    
    var body: some View {
            UIKitToSwiftUIBridge ()
    }
}

UIKitToSwiftUIBridge:

import SwiftUI
import UIKit

struct UIKitToSwiftUIBridge: UIViewControllerRepresentable {

    func makeUIViewController(context: Context) -> MyViewController {
        let viewcontroller = SharedViewController.sViewController
        return viewcontroller
    }

    func updateUIViewController(_ uiViewController: MyViewController, context: Context) {
        
    }
}

SharedViewController :

{
    static let sViewController = MyViewController ()
    
    private override init () {

    }
    
    @objc static func GetViewController ()->MyViewController
    {
        return SharedViewController.sViewController
    }
}

MyViewController.swift :

import UIKit

class MyViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = .black
       
        let button = UIButton (frame : CGRect (x:50, y:100, width:100, height:50))
       button.setTitle("Button", for: .normal)
       button.addTarget(self, action: #selector(ButtonAction (_:)), for: .touchDown)

    }

    @objc
    func ButtonAction (_ sender :UIButton)
    {
          let view = UIView (frame: CGRect (x:0, y:0, width:300, height:400))
          view.backgroundColor = .red
        
        let label = UILabel (frame: CGRect(x: 60, y: 50, width: 150, height: 60))
        label.text = " Label"
        
        view.addSubview(label)
        
        self.view.addSubview(view)  
     }

    @objc
    func ChangeColor () {
        
        self.view.backgroundColor = .white
    }
}

Objective C code where i need to access MyViewController's intance :

void ObjectiveC::ChangeColorOfViewController ()
{
    dispatch_async( dispatch_get_main_queue (),^{

        MyViewController * sharedobj = [SharedObject sharedMethod];
        [sharedobj ChangeColor];
        });
}
