попробуйте
myView.layer.cornerRadius = 10
let shadowPath = UIBezierPath(roundedRect: myView.bounds, cornerRadius: 10)
myView.layer.masksToBounds = false
myView.layer.shadowColor = UIColor.gray.cgColor
myView.layer.shadowOffset = CGSize(width: 0, height: 2)
myView.layer.shadowOpacity = 0.5
Или вы можете использовать Sketch Shadow
extension CALayer {
func applySketchShadow(
color: UIColor = .black,
alpha: Float = 0.5,
x: CGFloat = 0,
y: CGFloat = 2,
blur: CGFloat = 4,
spread: CGFloat = 0)
{
shadowColor = color.cgColor
shadowOpacity = alpha
shadowOffset = CGSize(width: x, height: y)
shadowRadius = blur / 2.0
if spread == 0 {
shadowPath = nil
} else {
let dx = -spread
let rect = bounds.insetBy(dx: dx, dy: dx)
shadowPath = UIBezierPath(rect: rect).cgPath
}
}
}
применить Sketch Shadow
myView.layer.cornerRadius = 10
let shadowPath = UIBezierPath(roundedRect: myView.bounds, cornerRadius: 10)
myView.layer.applySketchShadow(
color: .black,
alpha: 0.5,
x: CGFloat(0),
y: CGFloat(10),
blur: 20,
spread: 0)
myView.layer.shadowPath = shadowPath.cgPath
