[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
NSString *header = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@\"\r\n",@"file",@"pic.jpg"];

Have you tried using alamofire?

Alamofire.upload(multipartFormData: { (multipartFormData) in
// put your data to multipart here                        
}, to: url) { (result) in

    switch result {
    case .success(let upload, _, _):

    upload.responseJSON { response in

        switch response.result {
        case .success(let json):
        break:    
        case .failure(_):
        break:    
        }
    }
    case .failure(_):
    break:
    }
}
