Add drop shadow to UIImageView in Swift - iOS

In this article we will learn how to add drop shadow to an Image view.

 Step 1:

Add the following UIImageView extension:

extension UIImageView {
    func dropShadow() {
        self.layer.masksToBounds = false
        self.layer.shadowColor = UIColor.black.cgColor
        self.layer.shadowOpacity = 0.5
        self.layer.shadowOffset = CGSize(width: -1, height: 1)
        self.layer.shadowRadius = 1
        self.layer.shadowPath = UIBezierPath(rect: self.bounds).cgPath
        self.layer.shouldRasterize = true
        self.layer.rasterizationScale = UIScreen.main.scale
    }
}

Step 2:

We can use as follow:

let imageView = UIImageView()
imageView.frame = CGRect(x: view.frame.width/2 - 128, y: view.frame.height/2 - 80, width: 256, height: 160)
imageView.dropShadow()
imageView.image = UIImage(named: "Tiger.png")
imageView.backgroundColor = UIColor.white
view.addSubview(imageView)
