SWIFT - Setting layer.cornerRadius greater than the view height causes issues

I actually want to add a corner radius to a view on only one side. The radius is supposed to be of full height. This is my implementation.

someView.layer.cornerRadius = someView.frame.size.height
someView.layer.maskedCorners = [.layerMaxXMaxYCorner]

This does the job as required, but it adds extra shapes on other sides as shown below.

What might be the problem? enter image description here

This looks like an iOS bug, I was able to reproduce it

But usually you don't wanna set cornerRadius greater than half view minimum side, in your case:

someView.layer.cornerRadius = someView.frame.size.height / 2

I assume it'll produce result you're expecting:

Corner radius is radius of a circle inscribed in the corner of a rectangle, I think that's why there may be problems with radius bigger than side/2: circle doesn't fit a rectangle anymore
