Bother importing audio recordsdata in iOS Swift utilizing URLSession: Sudden Conduct with Multipart Type Knowledge

I am encountering points whereas trying to add audio recordsdata in my iOS Swift utility utilizing URLSession. The aim is to ship an audio file together with some parameters to a server endpoint utilizing multipart type information. Nevertheless, regardless of seemingly appropriate implementation, I am going through surprising conduct.

This is a short overview of my code’s performance:

I’ve a perform uploadFile(testID:) the place I assemble the URLRequest with vital headers and parameters. I then try to learn an audio file (sample-3s.mp3) from the primary bundle and add it to the request as part of multipart type information.

I am using a customized struct URLSession.File to signify every file to be uploaded, containing properties similar to title, fileName, information, and contentType.

Nevertheless, upon executing the request, I am not receiving the 422 standing code response from the server.

func uploadFile(testID:Int) {
      var recordsdata: [URLSession.File] = []
        var params: [String : Any] = ["test_id": testID]

guard let url = URL(string: "(baseURL)/speaking-file") else {return}
        var urlRequest = URLRequest(url: url)
        let boundary = UUID().uuidString

  urlRequest.httpMethod = "POST"
        
        if let token = Auth.shared.oAuth?.accessToken, let sort = Auth.shared.oAuth?.tokenType {
            urlRequest.addValue("(sort) (token)", forHTTPHeaderField: "Authorization")
        }
        
        urlRequest.addValue(Configuration.conf?.clientId ?? "", forHTTPHeaderField: "clientid")
        urlRequest.addValue(Configuration.conf?.clientSecret ?? "", forHTTPHeaderField: "clientsecret")

  urlRequest.setValue("multipart/form-data; boundary=(boundary)", forHTTPHeaderField: "Content material-Sort")
        
        if let audioUrl = Bundle.principal.url(forResource: "sample-3s", withExtension: "mp3") {
            do{
                let audioData = attempt Knowledge(contentsOf: audioUrl)
                let fileName = audioUrl.lastPathComponent
                let contentType = "audio/mp3" // Modify content material sort as wanted
                let file = URLSession.File(title: "file", fileName: fileName, information: audioData, contentType: contentType)
                recordsdata.append(file)
                
            }catch {
                print("Didn't convert to information")
            }
           
        }
        
        let information = createBodyWithMultipleImages(parameters: params, recordsdata: recordsdata, boundary: boundary)
       
        
        urlRequest.httpBody = information
        
        Logger.log(request: urlRequest)

   URLSession.shared.dataTask(with: urlRequest) { information, response, error in
            if let error {
                print("Error from file add")
                completion(.failure(error))
            }
            if let response {
                print("response type file add (response)")
            }
            
            if let information {
                do {
                    let json = attempt JSONSerialization.jsonObject(with: information,choices: [])
                    print(json)
                }catch {
                    print("Didn't seairlized json")
                }
                completion(.success(ResponseMessage(element: "File Uploaded")))
            }
        }.resume()  

}
