How to control shadow spread and blur?

Question

I have designed UI elements in sketch, and one of them has a shadow with blur 1 and spread 0. I looked at the doc for the views layer property and layer doesnt have anything

Answer 1

This code worked very well for me:

yourView.layer.shadowOpacity = 0.2 // opacity, 20%
yourView.layer.shadowColor = UIColor.black.cgColor
yourView.layer.shadowRadius = 2 // HALF of blur
yourView.layer.shadowOffset = CGSize(width: 0, height: 2) // Spread x, y
yourView.layer.masksToBounds = false
