The reason you are getting html code is that you are receiving some error from your web services look at the message "A PHP Error was encountered" in your output log.
The success in postman is because your request is in form-data. Compare the request from postman from Raw with the request you are generating.
You can refer this link for creating a request. But the code is in Objective-Cand you can use this link to convert the code, or you can use Alamofire to create requests and refer this link for creating multipart form-data requests using Alamofire
