Summary:?` instance to React Native. The layout system suppressed the values for `frame` and `backgroundColor` on my simple view and it wasn't clear why. After some debugging and hacking it became apparent that React Native needed to adjust those properties during layout. The workaround I found was to wrap my custom `UIView` in another `UIView` instance.
**Motivation**
When attempting to bridge a simple 100x100 red background `UIView` to ReactNative I could not get the view to show up as a `RCTView`. The view was there, but it was not 100x100 and it didn't have a red background. After a couple hours of poking around and debugging the call stacks on `setBackgroundColor` and `setFrame` it became apparent that React Native calls those messages on your `UIView` and sends new values. This is likely because of the layout system React Native uses.
I was encouraged to provide a small comment in the documentation if I thought others might find it useful. This PR is an attempt to provide a note in the documentation
