UIView shadow, cornerradius not working

Question

@IBOutlet weak var selectorSemiView: UIView!
@IBOutlet weak var blurEffect: UIVisualEffectView!
@IBOutlet var outerAreaRecognizer: UITapGestureRecognizer!
override func viewDidLoad() {
    super.viewDidLoad()
    selectorSemiView.layer.cornerRadius = 15
    selectorSemiView.layer.shadowColor = UIColor.gray.cgColor
    selectorSemiView.layer.shadowOffset = CGSize.zero
    selectorSemiView.layer.shadowRadius = 7

}

selectorSemiView is a container view

When I run this app, there is no shadow and no rounded corner.

What's wrong in my code?

your code is fine but you forget to set the opacity, if you need the more information you can get the another answer in SO, for e.g

 selectorSemiView.layer.cornerRadius = 15
    selectorSemiView.layer.shadowColor = UIColor.gray.cgColor
    selectorSemiView.layer.shadowOffset = CGSize.zero  
    selectorSemiView.layer.shadowOpacity = 1.0
    selectorSemiView.layer.shadowRadius = 7.0
    selectorSemiView.layer.masksToBounds =  false

output

When I include selectorSemiView.clipsToBounds = true, There is rounded corner but no shadow, but when I don't include selectorSemiView.clipsToBounds = true , there is shadow but now rounded corner – Junwoo Lee Apr 23 '17 at 04:40

Thats because shadow is applied **outside** the bounds and `clipsToBounds` well clips out. You need to fake this behaviour by adding another view of the same size and adding shadow on to it. – Rikh Apr 23 '17 at 08:54
why clip to bounds is not working when apply shadow by using this solution ? With my height constant when i am setting it to 0, inner content still displays. – Mitesh Dobareeya May 23 '20 at 07:28

While a possible answer, you haven't explained why this would work. – Apr 23 '17 at 16:45
When I set this property to true, nothing is shown at all. – inexcitus Jan 09 '22 at 07:30
