How to make the UIImage edges softer?

Question

I have a UIImage with a UIVisualEffectView on top of it. I want to make the edges softer to give it a shadow effect.

I tried playing around with maskToBounds but it doesn't make a difference.

let weekndImage = UIImage(named: "weeknd.jpg")
let weekndIV = UIImageView(image: weekndImage)
weekndIV.frame.size = CGSize(width: 200, height: 200)

let blur = UIBlurEffect(style: .light)
let blurView = UIVisualEffectView(effect: blur)


blurView.frame = weekndIV.bounds

weekndIV.addSubview(blurView)

weekndIV.layer.cornerRadius = 10
weekndIV.layer.masksToBounds = true

Answer 1

move these two lines after setting the blurView frame and before adding blurView to weekndIV view

weekndIV.layer.cornerRadius = 10
weekndIV.layer.masksToBounds = true

Answer 2

I think you want to have a shadow effect on your view. For that you can access shadowOpacity and shadowRadius from layer of your view

For example in Swift 2 :

class MyView : UIView {

    override func awakeFromNib() {
        layer.cornerRadius = 5.0
        layer.shadowOpacity = 0.8
        layer.shadowRadius = 5.0
        layer.shadowOffset = CGSizeMake(2.0, 2.0)
    }
}
