Hello, complete noob here..... is there an easy way to include SwiftUI code into a Storyboard (View Controller) Window for MacOS?

I tried subclassing the NSHostingController like so:

class HostingViewController: NSHostingController<MyView> {

     required init?(coder: NSCoder) {
         super.init(coder: coder,rootView: MyView());
     }

     override func viewDidLoad() {
         super.viewDidLoad()
     }
 }

with 'MyView' being the SwiftUI file that I want to appear in the window.

I'm unable to call this window from my AppDelegate ( i.e. when the user clicks on the 'Set Shortcut' menu item):


let menu = NSMenu()

menu.addItem(NSMenuItem(title: "Set Shortcut", action: #selector(AppDelegate.Shortcut(sender:)), keyEquivalent: "" ))
statusItem.menu = menu
}
    @objc func Shortcut(sender: NSMenuItem){

        //call the HostingViewController here

        }

Have tried various bits of code unsuccessfullly to call the window at the point where the code is commented.

Much obliged for any assistance.

Use UIHostingController:

https://developer.apple.com/documentation/swiftui/uihostingcontroller

let swiftUIView = SomeSwiftUIView() // swiftUIView is View
let viewCtrl = UIHostingController(rootView: swiftUIView)

See implementation details here:
