I want to download file from amazon s3. Here is my code

        let expression = AWSS3TransferUtilityDownloadExpression()



        expression.downloadProgress = {(task: AWSS3TransferUtilityTask, bytesSent: Int64, totalBytesSent: Int64, totalBytesExpectedToSend: Int64) in



            self.progressLabel.text = "Downloaded (ByteCountFormatter.string(fromByteCount: progress.completedUnitCount, countStyle: .file)) of (ByteCountFormatter.string(fromByteCount: progress.totalUnitCount, countStyle: .file) ) "

                self.progressUpload.setProgress(Float(progress.fractionCompleted), animated: true)



        }



        completionHandler = { (task, location, data, error) -> Void in

                if ((error) != nil){

                    print("Failed with error")

                    print("Error: (error!)")

                }

                else{

                    //Set your image

                    var downloadedImage = UIImage(data: data!)

                }

        }



        let transferUtility = AWSS3TransferUtility.default()



        transferUtility.downloadToURL(nil, bucket: S3BucketName, key: saveFileWithName, expression: expression, completionHander: completionHandler).continueWithBlock { (task) -> AnyObject! in

            if let error = task.error {

                print("Error: (error.localizedDescription)")

            }

            if let exception = task.exception {

                print("Exception: (exception.description)")

            }

            if let _ = task.result {

                print("Download Starting!")

            }

            return nil;

        }

but it is giving me error that "Value of type 'AWSS3TransferUtilityDownloadExpression' has no member 'downloadProgress'".

Can I able to download using alamofire? This is my code to download simple file using alamofire. but simple url file is downloaded but amazon s3 bucket file is not downloading. Please help me with it.

        let url = URL(string: "(AppConstants.ImageServerURL)(fileUrl)")

        let destination: DownloadRequest.DownloadFileDestination = { _, _ in

            let documentsURL = Utilities.getDocumentsDirectory().appendingPathComponent("(StringConstants.DownloadFolderName)/(saveFileWithName).(fileUrl.fileExtension())")

            print(documentsURL)

            return (documentsURL, [.removePreviousFile])

        }



        self.progressUpload.setProgress(0, animated: true)

        UIViewController.current().present(self.uploadAlertView, animated: true, completion: nil)

        self.request = Alamofire.download(

            url!,

            method: .get,

            parameters: nil,

            encoding: JSONEncoding.default,

            headers: ApplicationData.sharedInstance.authorizationHeaders,to: destination).downloadProgress(closure: { (progress) in

                //progress closure

                self.progressLabel.text = "Downloaded (ByteCountFormatter.string(fromByteCount: progress.completedUnitCount, countStyle: .file)) of (ByteCountFormatter.string(fromByteCount: progress.totalUnitCount, countStyle: .file) ) "

                self.progressUpload.setProgress(Float(progress.fractionCompleted), animated: true)

            }).response(completionHandler: { (response) in



                self.uploadAlertView.dismiss(animated: true, completion: nil)

                // check result is success

                guard response.error == nil else {



                    failure()

                    return

                }



                success()



            })

Any help would be appreciated. Thank you.
