Uploading a image with Alamofire in iOS

you can try this:

Alamofire.upload( multipartFormData: { multipartFormData in multipartFormData.append(imgData!, withName: "img", fileName: "jpg", mimeType: "image/jpeg") }, to: UPLOAD_IMAGE_URL, encodingCompletion: { (encodingResult) -> Void in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in let result = response.data do { print("success") }catch { print("error") } } case .failure(let encodingError): print(encodingError) } }) 

For the first look it's missing the HTTP method: .post, and the mimeType should be "image/jpeg", not "image/jpg".

See this:

 Alamofire.upload(multipartFormData: { multipartFormData in multipartFormData.append(imgData, withName: "data", fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "image/jpeg") multipartFormData.append(operaID.data, withName: "id") }, to: YOUR_URL_HERE, method: .post, encodingCompletion: { result in switch result { case .success(let upload, _, _): upload.uploadProgress(closure: { (progress) in print("Upload Progress: \(progress.fractionCompleted)") }) upload.responseJSON { response in print("Upload image response:", response.result.value) } case .failure(let encodingError): print("Error while uploading image:", encodingError) } }) 

Is there any server log indicating error? Can you add breakpoints to the server code and run it on localhost to check what you have in your controller?

In case the server endpoint is http put this in your Info.plist:

<key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> 

 Alamofire.upload(multipartFormData: { multipartFormData in if let img = image, let imageData = img.jpegData(compressionQuality: 0.6) { multipartFormData.append(imageData, withName: imageName, fileName: "temp.jpg", mimeType: "image/jpg") } for (key, value) in parameter ?? [:] { if value is String || value is Int { multipartFormData.append("\(value)".data(using: .utf8)!, withName: key) } } }, to: url, headers: headers, encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _ , _ ): upload.responseJSON { response in debugPrint(response) if response.response?.statusCode == 200 { if let jsonData = try? JSONSerialization.data(withJSONObject: response.result.value!, options: .prettyPrinted) { print("Response: \n",String(data: jsonData, encoding: String.Encoding.utf8) ?? "nil") } success(response.result.value! as AnyObject) }else { let res = response.result.value! as AnyObject let msg = res["Message"] as? String if msg != nil { failure(msg!) }else { failure("") } } } case .failure(let encodingError): print(encodingError) failure(encodingError.localizedDescription) } })
