In SwiftUI, how to use UIHostingController inside an UIView or as an UIView?

Question

An alternative question title could be \"How to add an UIHostingController\'s view as subview for an UIView?\".

I am creating a new piece of UI comp

Answer 1

I have some idea in mind.

1. Wrap the SwiftUI with a UIHostingController
2. Initialize the controller
3. Add the new controller as a child view controller
4. Add the controller view as a subview to where it should go

Thus:

addChild(hostingViewController)
hostingViewController.view.frame = ...
view.addSubview(hostingViewController.view)
hostingViewController.didMove(toParent: self)

A view controller always uses other view controllers as views.
