Upload multiple images in swift using Alamofire

Swift 3Just use "[]" with image upload param to make it array of images.

Alamofire.upload(multipartFormData: { multipartFormData in            // import image to request            for imageData in imagesData {                multipartFormData.append(imageData, withName: "\(imageParamName)[]", fileName: "\(Date().timeIntervalSince1970).jpeg", mimeType: "image/jpeg")            }            for (key, value) in parameters {                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)            }        }, to: urlString,            encodingCompletion: { encodingResult in                switch encodingResult {                case .success(let upload, _, _):                    upload.responseJSON { response in                    }                case .failure(let error):                    print(error)                }        })

This one helps me:

private func urlRequestWithComponentsForUploadMultipleImages(urlString:String, parameters:Dictionary<String, String>, imagesData:[Data], imageName: String) -> (URLRequestConvertible , Data) {    // create url request to send    var mutableURLRequest = URLRequest(url: NSURL(string: urlString)! as URL)    mutableURLRequest.httpMethod = Alamofire.HTTPMethod.post.rawValue    let boundaryConstant = "myRandomBoundary12345";    let contentType = "multipart/form-data;boundary="+boundaryConstant    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")    // create upload data to send    var uploadData = Data()    // add image    for data in imagesData {        uploadData.append("\r\n--\(boundaryConstant)\r\n".data(using: String.Encoding.utf8)!)        uploadData.append("Content-Disposition: form-data; name=\"\(imageName)\"; filename=\"\(Date().timeIntervalSince1970).jpeg\"\r\n".data(using: String.Encoding.utf8)!)        uploadData.append("Content-Type: image/jpeg\r\n\r\n".data(using: String.Encoding.utf8)!)        uploadData.append(data)    }    // add parameters    for (key, value) in parameters {        uploadData.append("\r\n--\(boundaryConstant)\r\n".data(using: String.Encoding.utf8)!)        uploadData.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".data(using: String.Encoding.utf8)!)    }    uploadData.append("\r\n--\(boundaryConstant)--\r\n".data(using: String.Encoding.utf8)!)    print("upload",parameters)    return (mutableURLRequest , uploadData)}

here is my solution and it will work 100% no bugs..

        Alamofire.upload(multipartFormData: { (multipartFormData : MultipartFormData) in            let count = imageToUpload.count            for i in 0..<count{                multipartFormData.append(imageToUpload[i], withName: "morephoto[\(i)]", fileName: "photo\(i).jpeg" , mimeType: "image/jpeg")            }            for (key, value) in parameterrs {                    multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)            }            print(multipartFormData)        }, to: url!) { (result) in                switch result {                case .success(let upload, _ , _):                    upload.uploadProgress(closure: { (progress) in                        print("uploding: \(progress.fractionCompleted)")                    })                    upload.responseJSON { response in                    print(response.result.value!)                    let resp = response.result.value! as! NSDictionary                    if resp["status"] as! String == "success"{                        print(response.result.value!)                        let alert = UIAlertController(title: "Alert", message: "Image Upload Successful", preferredStyle: UIAlertControllerStyle.alert)                        alert.addAction(UIAlertAction(title: "Okay", style: UIAlertActionStyle.default, handler: nil))                        self.present(alert, animated: true, completion: nil)                    }                    else{                    }                }            case .failure(let encodingError):                print("failed")                print(encodingError)            }        }

in this the imagetoupload array is the array of image data which i have made before.
