How to create multipart form data request for image and json data using URLSession- Swift

Question

I need to send an image and json data to the server by using multipart/form-data request by using URLSession. Please refer the below screenshot for request.

I can successfully able to upload the image and json data by using postman. But i am struggling to upload the image and json data by using URLSession

Please refer to the below code

    let session = URLSession.shared        
    let boundary = UUID().uuidString
    
    var urlRequest = URLRequest(url: URL(string: "https://dev.example.com/api/msg/sendmsg")!)
    urlRequest.httpMethod = "POST"
    urlRequest.setValue(authToken, forHTTPHeaderField: Key.RequestParam.authToken)
    
    urlRequest.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    
    var data = Data()
    
    data.append("\r\n--\(boundary)\r\n".data(using: .utf8)!)
    
    let imageName = "file"
    data.append("Content-Disposition: form-data; name=\"\(imageName)\"; filename=\"\(imageName)\" \r\n".data(using: .utf8)!)
    data.append("Content-Type: image/jpeg \r\n".data(using: .utf8)!)
    data.append(imageData)
    
    data.append("\r\n--\(boundary)\r\n".data(using: .utf8)!)
    
    data.append("Content-Disposition: form-data; name=msgRequest \r\n".data(using: .utf8)!)
    data.append("Content-Type: application/json \r\n".data(using: .utf8)!)
    data.append(msgRequest)
    
    data.append("\r\n--\(boundary)--\r\n".data(using: .utf8)!)
    
    urlRequest.httpBody = data
    
    session.dataTask(with: urlRequest) { responseData, response, error in
        if(error != nil){
            print("\(error!.localizedDescription)")
        }
        
        guard let responseData = responseData else {
            print("no response data")
            return
        }
        if let responseString = String(data: responseData, encoding: .utf8) {
            print("uploaded to: \(responseString)")
        }
    }.resume()
