How to get `UIViewRepresentable` to update when `ObservableObject` changes

Could anyone provide an example to get a `UIViewRepresentable` to call `updateUIView(:context:)` when an `ObservableObject` changes?


Say I have `Foo: UIViewRepresentable` and `Observable: Object` I tried pretty much all combinations I can think of;


- Use `EnvironmentObject`, `ObservedObject`

- On `Foo.Coordinator`, `Foo`, `Foo`'s parent,

- Using Xcode 11.3.1 and 11.4 beta.
