Swift 4 Swift 5 easy way in 1 line

Usage:

//MARK:- Corner Radius of only two side of UIViews
self.roundCorners(view: yourview, corners: [.bottomLeft, .topRight], radius: 12.0)

Function:

//MARK:- Corner Radius of only two side of UIViews
func roundCorners(view :UIView, corners: UIRectCorner, radius: CGFloat){
        let path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))
        let mask = CAShapeLayer()
        mask.path = path.cgPath
        view.layer.mask = mask
}

In Objective-C

Usage:

[self.verticalSeparatorView roundCorners:UIRectCornerTopLeft radius:10.0];

Function used in a Category (only one corner):

-(void)roundCorners: (UIRectCorner) corners radius:(CGFloat)radius {
        UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:self.bounds byRoundingCorners:corners cornerRadii:CGSizeMake(radius, radius)];
        CAShapeLayer *mask = [[CAShapeLayer alloc] init];
        mask.path = path.CGPath;
        self.layer.mask = mask;
    }
