How to get value of completed task while uploading video to AWS? - ios

Question

I have implemented the AWSS3 to upload the video to the AWS server and also I want to get the value of task which has been completed using AWSS3TransferUtilityUploadExpression() to show the value on progress bar. But I am not getting the value please see the below code atached.
///1
typealias progressBlock = (_ progress: Double) -> Void //2
typealias completionBlock = (_ response: Any?, _ error: Error?) -> Void //3
//2
// Upload video from local path url
func uploadVideo(videoUrl: URL, progress: progressBlock?, completion: completionBlock?) {
print("video url is \(videoUrl)")
let fileName = self.getUniqueFileName(fileUrl: videoUrl)
print("keyname \(fileName)")
self.uploadfile(fileUrl: videoUrl, fileName: fileName, contenType: "video", progress: progress, completion: completion)
}
//method to upload the video
private func uploadfile(fileUrl: URL,
fileName: String,
contenType: String,
progress: progressBlock?, completion: completionBlock?) {
// Upload progress block
let expression = AWSS3TransferUtilityUploadExpression()
expression.progressBlock = {(task, awsProgress) in
guard let uploadProgress = progress else { return }
DispatchQueue.main.async {
debugPrint("completed portion of the task is \(awsProgress.fractionCompleted)")
uploadProgress(awsProgress.fractionCompleted)
//progress!(awsProgress.fractionCompleted)
}
}
// Completion block
var completionHandler: AWSS3TransferUtilityUploadCompletionHandlerBlock?
completionHandler = { (task, error) -> Void in
DispatchQueue.main.async(execute: {
if error == nil {
let url = AWSS3.default().configuration.endpoint.url
let publicURL = url?.appendingPathComponent(self.bucketName).appendingPathComponent(fileName)
if let completionBlock = completion {
completionBlock(publicURL?.absoluteString, nil)
}
} else {
if let completionBlock = completion {
print("error is at completionBlock \(error?.localizedDescription)")
completionBlock(nil, error)
}
}
})
}
// Start uploading using AWSS3TransferUtility
let awsTransferUtility = AWSS3TransferUtility.default()
awsTransferUtility.uploadFile(fileUrl, bucket: bucketName, key: fileName, contentType: contenType, expression: expression, completionHandler: completionHandler).continueWith { (task) -> Any? in
if let error = task.error {
print("error is: \(error.localizedDescription)")
}
if let url = task.result {
// your uploadTask
print("url is \(url)")
}
return nil
}
}

Install cocoapods pod 'AWSS3'.
Here filePath is the path of the file to be uploaded.
func saveModelInAmazonS3() {
let remoteName = fileName + ".mov" //extension of your file name
let S3BucketName = "bucketName"
let uploadRequest = AWSS3TransferManagerUploadRequest()!
uploadRequest.body = filePath!
uploadRequest.key = remoteName
uploadRequest.bucket = S3BucketName
uploadRequest.contentType = "application/zip"
uploadRequest.acl = .publicRead
uploadRequest.uploadProgress = { (bytesSent, totalBytesSent, totalBytesExpectedToSend) -> Void in
DispatchQueue.main.async(execute: { // here you can track your progress
let amountUploaded = totalBytesSent
let fileSize = totalBytesExpectedToSend
print("\(amountUploaded)/\(fileSize)")
let progress = (CGFloat(amountUploaded) / CGFloat(fileSize)))
})
}
let transferManager = AWSS3TransferManager.default()
transferManager.upload(uploadRequest).continueWith(block: { (task: AWSTask) -> Any? in
if let error = task.error {
self.delegate.errorInUpload(uploadState: self.uploadState)
print("Upload failed with error: (\(error.localizedDescription))")
}
if task.result != nil {
let url = AWSS3.default().configuration.endpoint.url
print("Uploaded to:\(String(describing: url))")
}
return nil
})
}
