when we creating snapshot of UIView, why do we check if it is a imageview or not, is it neccassary? I did not understand, and can it make performance slower, I suspect that. Thanks for your effort.

Its so they resize better. A normal snapshot just copies the rendered bitmap into a new UIView and is not a clone of the view. So if an image is upsized/scaled the image resolution can get weird and not look great
