How to upload an arbitrary number of files with Swift and Alamofire? -


i'm trying access rest api lets me upload different number of files, depending on situation. i've got following code alamofire i'm not sure how change can upload 1 file, 2 files, or ten files.

    alamofire.upload(         .post,         "https://httpbin.org/post",         multipartformdata: { multipartformdata in             multipartformdata.appendbodypart(fileurl: farmfileurl, name: "xml-file-farm")             multipartformdata.appendbodypart(fileurl: farmfileurl, name: "csv-measurement-file-1")             multipartformdata.appendbodypart(fileurl: farmfileurl, name: "csv-measurement-file-2")         },         encodingcompletion: { encodingresult in             switch encodingresult {             case .success(let upload, _, _):                 upload.responsejson { response in                     debugprint(response)                 }             case .failure(let encodingerror):                 print(encodingerror)             }         }     )

the problem see can't define array of files using 'multipartformdata' because doesn't exist until you're inside 'upload' method.

make array of tuple contains filename , url , pass it: 

 func uploadfiles(files:[(string,nsurl)]){         alamofire.upload(             .post,             "https://httpbin.org/post",             multipartformdata: { multipartformdata in                  (filename, fileurl) in files{                     multipartformdata.appendbodypart(fileurl: fileurl, name: filename)                 }             },             encodingcompletion: { encodingresult in                 switch encodingresult {                 case .success(let upload, _, _):                     upload.responsejson { response in                         debugprint(response)                     }                 case .failure(let encodingerror):                     print(encodingerror)                 }             }         )     }
