Of course! Here's how you would do it:

Alamofire.upload(
    .POST,
    URLString: "http://httpbin.org/post",
    multipartFormData: { multipartFormData in
        multipartFormData.appendBodyPart(fileURL: unicornImageURL, name: "unicorn")
        multipartFormData.appendBodyPart(fileURL: rainbowImageURL, name: "rainbow")
    },
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .Success(let upload, _, _):
            upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
                print(totalBytesRead)
            }
            upload.responseJSON { request, response, result in
                debugPrint(result)
            }
        case .Failure(let encodingError):
            print(encodingError)
        }
    }
)

There is a progress() in Request itself, that is the one you are looking for.

Use

upload.responseJSON { response in
                debugPrint(result)
            }

instead of

upload.responseJSON { request, response, result in
                debugPrint(result)
            }

About "Cannot call value of non-function type 'NSProgress'" error: it's fixed by renaming or removing "progress" field of type NSProgress in Request class. Then it is able to choose the right "progress" of function type.
