Answer 1

Solved this with the help of @Paolo and below is the working code.

Swift 3.2

extension UIView {

    func roundCorners(corners:UIRectCorner, radius: CGFloat) {

        DispatchQueue.main.async {
            let path = UIBezierPath(roundedRect: self.bounds,
                                    byRoundingCorners: corners,
                                    cornerRadii: CGSize(width: radius, height: radius))
            let maskLayer = CAShapeLayer()
            maskLayer.frame = self.bounds
            maskLayer.path = path.cgPath
            self.layer.mask = maskLayer
        }
    }
}

for calling this function use below line and mention which corners you want to round

self.myView.roundCorners(corners: [.topLeft, .topRight, .bottomLeft, .bottomRight], radius: 8.0)
