Upload Image to server in Swift

Upload image to server in Swift 4.1 and Xcode 9.4.1

Here i'm posting only Upload image code.

In this below code you need to replace your "image file name and uploaded file name".

Call this function like :  uploadImageOne()

func uploadImageOne(){

        

    let imageData = UIImageJPEGRepresentation(yourImage!, 1.0)//Replace your image

        

    if imageData != nil{

       var request = URLRequest(url: NSURL(string:urlString)! as URL)//Send your URL here

       print(request)

       request.httpMethod = "POST"

            

       let boundary = NSString(format: "---------------------------14737809831466499882746641449")

       let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)

       //  println("Content Type \(contentType)")

       request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")

            

       var body = Data()

            

       body.append(NSString(format: "\r\n--%@\r\n", boundary).data(using: String.Encoding.utf8.rawValue)!)

       body.append(NSString(format:"Content-Disposition: form-data;name=\"title\"\r\n\r\n").data
                            (using:String.Encoding.utf8.rawValue)!)

       body.append("Hello".data(using: String.Encoding.utf8, allowLossyConversion: true)!)

            

       body.append(NSString(format: "\r\n--%@\r\n", boundary).data(using: String.Encoding.utf8.rawValue)!)

       body.append(NSString(format:"Content-Disposition: form-data;name=\"uploaded_file\";filename=\"image.jpg\"\\r\n").data
                           (using:String.Encoding.utf8.rawValue)!) //Here replace your image name and file name

       body.append(NSString(format: "Content-Type: image/jpeg\r\n\r\n").data(using: String.Encoding.utf8.rawValue)!)

       body.append(imageData!)

       body.append(NSString(format: "\r\n--%@\r\n", boundary).data(using: String.Encoding.utf8.rawValue)!)

            

       request.httpBody = body

            

       let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil     
           else { // check for fundamental networking error

           print("error=\(String(describing: error))")

           SharedClass.sharedInstance.alert(view: self, message: "\(String(describing: error!.localizedDescription))")

           return

        }

                

        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode == 500 {

            SharedClass.sharedInstance.alert(view: self, message: "Server Error")

        } else if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors

             print("statusCode should be 200, but is \(httpStatus.statusCode)")

             print("response = \(String(describing: response))")

        }

      
        //This can print your response in string formate        

        let responseString = String(data: data, encoding: .utf8)

         //            let dictionary = data

         //            print("dictionary = \(dictionary)")

         print("responseString = \(String(describing: responseString!))")

                

         do {

             self.response3 = (try JSONSerialization.jsonObject(with: data, options: []) as? [String: AnyObject])!

             print(self.response3)

                    

             if (((self.response3["Response"] as? [String : Any])?["status"]) as! String == "SUCCESS") {

                   let message = (self.response3["Response"] as? [String : Any])?["message"] as? String

                       SharedClass.sharedInstance.alert(view:self, message: message)

              } else {

                    let message = (self.response3["Response"] as? [String : Any])?["message"] as? String

                        SharedClass.sharedInstance.alert(view:self, message: message)

                    }

          } catch let error as NSError {

               print(error)

               print(error.localizedDescription)

          }

       }

            

        task.resume()

            

     }

        

    }
