How to upload multiple file using alamofire with showing progress?

Question

I want to upload multiple files to server in iOS. I have data as NSData and I want to upload it to server. I am using alamofire for uploading the data. I have gone through their documentation but could not find good answer. I am not able to understand how will the code below work with NSData & multiple images. Please provide solution.

let fileURL = Bundle.main.url(forResource: "video", withExtension: "mov")

Alamofire.upload(fileURL, to: "https://httpbin.org/post")
    .uploadProgress { progress in // main queue by default
        print("Upload Progress: \(progress.fractionCompleted)")
    }
    .downloadProgress { progress in // main queue by default
        print("Download Progress: \(progress.fractionCompleted)")
    }
    .responseJSON { response in
        debugPrint(response)
    }

Use the following code for multiple image uploads using Alamofire. You can find documentation around it here : -

Alamofire.upload(
multipartFormData: { multipartFormData in
    multipartFormData.append(data, name: "imageFile",
                 fileName: "image.jpg", mimeType: "image/jpeg"), 
    multipartFormData.append(data1, name: "image1File",
                fileName: "image1.jpg", mimeType: "image/jpeg")
},
to: "https://httpbin.org/post", //URL,
headers: headers,
encodingCompletion: { encodingResult in
    switch encodingResult {
    case .success(let upload, _, _):
        upload.responseJSON { response in
            debugPrint(response)
        }
        upload.uploadProgress(closure: { //Get Progress
                progress in
                    print(progress.fractionCompleted)
            })
    case .failure(let encodingError):
        print(encodingError)
    }
})

Note: This is using Alamofre 4.0
