How to set corner Radius to UIImage not UIImageView in iOS Swift

Here is an extension for UIImage to set corner radius for it, not dealing with UIImageView.

 extension UIImage {
        // image with rounded corners
        public func withRoundedCorners(radius: CGFloat? = nil) -> UIImage? {
            let maxRadius = min(size.width, size.height) / 2
            let cornerRadius: CGFloat
            if let radius = radius, radius > 0 && radius <= maxRadius {
                cornerRadius = radius
            } else {
                cornerRadius = maxRadius
            }
            UIGraphicsBeginImageContextWithOptions(size, false, scale)
            let rect = CGRect(origin: .zero, size: size)
            UIBezierPath(roundedRect: rect, cornerRadius: cornerRadius).addClip()
            draw(in: rect)
            let image = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()
            return image
        }
    }

Usage:

yourUIImage.withRoundedCorners(radius: 10)

You can try AspectFill mode, instead of AspectFit. Using AspectFill, image will fill imageView completely, and there'll be rounded corners.
