Question

I\'m receiving image from a server, then based on a color chosen by the user, the image color will be changed.

I tried the following :

extension UIImage {
    func imageWithColor(_ color: UIColor) -> UIImage? {
        var image: UIImage? = withRenderingMode(.alwaysTemplate)
        UIGraphicsBeginImageContextWithOptions(size, false, scale)
        color.set()
        image?.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
        image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}
