Get upload progress for multipart upload Alamofire5

Question

Before Alamofire5 we could user encodingReesult of uploadRequest to get uploadProgress. But now after uploading Alamofire to version 5, based on Alamofire Documentation, we can use .uploadProgress in order to get upload progress handler.

Here's my code:

AF.upload(multipartFormData: { multipartFormData in
            multipartFormData.append(fileContent, withName: "file", fileName: filePath.lastPathComponent)
            multipartFormData.append(token.data(using: .utf8)!, withName: "token")
        }, to: uploadURL)
        .uploadProgress { progress in 
            print(progress)
        }
        .responseJSON { [weak self] response in
            print(response)
        }

But uploadProgress closure never called during upload progress.

I've checked many stackoverflow questions but no one worked.

Answer 1

If u happen to have installed a library for network traffic debugging like Wormholy, then, checkout this issue thread. In short note, it's the issue with the library & uninstalling it, solves the problem. Not sure with other network debuggers though. To make things clear, try to playaround in a new, clean project and see if alamofire works in such environment.

Answer 2

I also have this issue. I try to solve it by many methods. In the end, I uninstall the pod "CocoaDebug". It worked. So I think maybe is CocoaDebug disturbing the network.

Answer 3

replace your

.uploadProgress { progress in 
            print(progress)
        }

with

.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})

it will give you output as :

Upload Progress: 0.035203331252732804
Upload Progress: 0.035203331252732804
Upload Progress: 0.0528049968790992

Edit :

AF.upload(multipartFormData: { MultipartFormData in
        MultipartFormData.append(fileContent, withName: "file" , fileName: filePath.lastPathComponent , mimeType: "image/jpeg")
        for(key,value) in dictonary {
            MultipartFormData.append(token.data(using: String.Encoding.utf8)!, withName: "token")
        }
    }, to: uploadURL, method: .post, headers: ["Content-Type": "application/json")

        .uploadProgress(closure: { (progress) in
            print("Upload Progress: \(progress.fractionCompleted)")
        })

        .responseJSON{ (response) in
            debugPrint("SUCCESS RESPONSE: \(response)")
         }
