HostingView

This repo is to demonstrate when a parent UIViewRepresentable is dismissed, its child view still get re-rendered.

Steps

1. Run app, console should print 1 appear
2. Tap To Normal
3. 1 appear is printed on console, although we expect not to print anything as the parent view has been replaced by another view
4. If we comment out super.viewDidAppear (line 18 of UIHostingView.swift) or super.viewWillDisappear (line 24 of UIHostingView.swift), the message 1 appear will not be printed. However not calling super may cause other unwanted issues.
