In Swift 3 use this code

@IBAction func whatsappShareWithImages(_ sender: AnyObject) {
    let urlWhats = "whatsapp://app"
    if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed) {
        if let whatsappURL = URL(string: urlString) {

            if UIApplication.shared.canOpenURL(whatsappURL as URL) {

                if let image = UIImage(named: "whatsappIcon") {
                    if let imageData = UIImageJPEGRepresentation(image, 1.0) {
                        let tempFile = URL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/whatsAppTmp.wai")
                        do {
                            try imageData.write(to: tempFile, options: .atomic)
                            self.documentInteractionController = UIDocumentInteractionController(url: tempFile)
                            self.documentInteractionController.uti = "net.whatsapp.image"
                            self.documentInteractionController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)

                        } catch {
                            print(error)
                        }
                    }
                }

            } else {
               print("Cannot open whatsapp")
            }
        }
    }

}
