Along the lines of this question—if you take a screenshot on an iPhone X, how is the camera cutout at the top of the screen handled? Is there just a black region of the appropriate shape and size at the top of the image?
The simulator behaves differently to an actual device. Screenshots from a real device do not have a cutout, nor rounded corners.
Screenshots taken on iPhone X ignore the existence of the notch
