        func flipImageOnHorizontalAxis(theImage: UIImage,imageView:UIImageView) -> UIImage {

            var orient: UIImageOrientation!
            let imgOrientation = theImage.imageOrientation

            UIView.transition(with: imageView, duration: 0.4, options: .transitionCrossDissolve, animations: {() -> Void in

        func flipImageOnVerticalAxis(theImage: UIImage,imageView:UIImageView) -> UIImage {

            var orient: UIImageOrientation!
            let imgOrientation = theImage.imageOrientation

            UIView.transition(with: imageView, duration: 0.4, options: .transitionCrossDissolve, animations: {() -> Void in

            let mirroredImage = UIImage(cgImage: theImage.cgImage!, scale: 1.0, orientation: orient)
            //let mirroredImage = UIImage(CGImage: theImage.CGImage!, scale: 1.0, orientation: orient)
            return mirroredImage
        }

//MARK: To call the above function this can be done like this:

flipImageOnHorizontalAxis(theImage: imageView.image!, imageView: imageView)

or

flipImageOnVerticalAxis(theImage: imageView.image!, imageView: imageView)
