HighlightOverlay
Puts a darker background over your SwiftUI Views with a mask that cuts out a hole for your currently selected view.
Selected view can be chosen by specifying an identifier for your view via modifier. It is then passed to withHighlightOverlay as a binding.
The view coordinates are then tracked using PreferenceKey to maintain correct position for the cutout.
Example:
Black circle has an empty identifier which is used to remove the overlay. This example contains an animation for the highlight which can be easily removed if needed.
