How to round the corners of a UIView

Swift version: 5.10

Paul Hudson    @twostraws   

All UIView subclasses have the ability to round their corners thanks to their underlying CALayer – that's the bit that handles the actual drawing of your views. To round the corners of a view, use this code:

yourView.layer.cornerRadius = 10

The number you specify is how far the rounding should go, measured in points. So if you have a view that's 100x100 points and give it a cornerRadius property of 50, it will look like a circle.

Note that some types of view don't have clipsToBounds enabled by default, which means their corners will not round until you enable this property.
