    if let whatsappURL = NSURL(string: urlString) {
        if UIApplication.shared.canOpenURL(whatsappURL as URL) {
            UIApplication.shared.open(whatsappURL as URL, options: [:], completionHandler: { (Bool) in

            })
        } else {
            // Handle a problem
        }
    }
}
