Dismissing UIHostingController from SwiftUI.md

• Instantiate UIHosting Controller
• pass a reference to self which is of type UIDocumentBrowserViewController

//This is somewhere in the present method of my UIDBVC subclass
let documentViewController = UIHostingController(rootView: SomeView(rootVC: self))

* In the UIDBVC subclass I created this method
```swift
func dismissVC() {
  dismiss(animated: true, completion: nil)
}

• The SwiftUI View calls the dismissVC method of the UIDBVC subclass

struct SomeView: View {

  var rootVC: myDocumentBrowserViewControllerSubclass
  
  var body: some View{
    Button(
      action: { self.rootVC.dismissVC() },
      label: { Text("Dismiss this View") }
    )
  }
}
