Hi i have found that If your application creates photos, videos or audio notes and you’d like your users to share these media using WhatsApp, you can use the Document Interaction API to send your media to your WhatsApp contacts and groups.

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 {
                    // Cannot open whatsapp
                }
            }
        }

    }

Add this code in your app "plist"

  <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>whatsapp</string>
    </array>
