Haben Sie versucht alamofire mit?

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: 
    } 
}
