What did you do?

I was trying to present the picker view controller modally (custom view container).

What did you expect to happen?

The view gets properly displayed without any warnings.

What happened instead?

I got warnings about breaking layout constraints. It seems like the preview color view has a fixed height, therefore I need to provide the exact height for the color picker

We should set the popoverPresentationController's sourceView and sourceRect to prevent it form crashing on larger devices.
