Could you help me please with this

I'm trying to pull data from API using Alamofire. Is it possible to pull simple data like ["title"] and Image in the same request and populate it in table view?

Here's my code:

Alamofire.request(baseURL).responseJSON { (response) in

        switch response.result {

        case .success:

            if let value = response.result.value{

                let json = JSON(value)

                json.forEach({ (temp) in

                    let title = temp.1["title"].stringValue

                    let run = temp.1["run"].stringValue

                    let image = temp.1["thumb"].stringValue

                    let newmodel = Schedule(title: title, run: run, image: image)

                    self.scheduleArray.append(newmodel)

                })



            }

        case .failure(let error):

            print(error.localizedDescription)

        }

        DispatchQueue.main.async {

            self.tableView.reloadData()

        }

    }

}

You can get the base data at first and after that get every image with single request

get base data with this code :

 func POSTWithLoad(urlString: String,paramaters: [String: AnyObject]? = nil,success:@escaping (_ responseObject: AnyObject?) -> Void ,failure: @escaping (_ error: String?) -> Void ) {



 Alamofire.request(baseUrlDev+urlString, method: .post, parameters:paramaters, encoding: URLEncoding.default, headers: headers).responseJSON(completionHandler: { (responseData) in



            if (responseData.result.error == nil && responseData.result.isSuccess == true) {



            //success



             success(responseData)



            } else {



            //fauiler



            failure("UnKnowen Data")



            }



     })

}

and use this for getImage :

func getImage(link : String , completion : @escaping (_ imageWithLink : (link : String,image : UIImage)) -> Void){

    var image = UIImage(named: "placeholder")



    URLSession.shared.dataTask(with: NSURL(string: link.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!)! as URL, completionHandler: { (data, response, error) -> Void in

        if error != nil {

            print("errorLoadIamge : "+link)

            //completion(image)

            print(error)

            return

        }

        DispatchQueue.main.async(execute: { () -> Void in

            let mimage = UIImage(data: data!)

            if(mimage != nil){

                image = mimage!

                completion((link : link , image : image))

                print("successLoadIamge : "+link)

                return

            }

        })



    }).resume()

}

then can use it in your ViewContoller like this :

    let products : [Product] = 

    let productImages : [String] = 



POSTWithLoad(urlString: "YApiLink" , paramaters: requestParameters as [String : AnyObject]?, success: { (successObject) in



            products = Mapper<Product>().mapArray(JSONObject : successObject)

            productsImages = 

            print(successObject)



        }, failure :{ (failureObject) in



            print(failureObject)



        }

        )





    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {



        let product = products[indexPath.row]   

     let cell =  YourTableView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath) as! YourTableViewCell



        if let imageAndLink = productsImages.first(where: { $0.link == cell.product?.productImage})

        {cell.pImage?.image = imageAndLink.image}

        else{ cell.pImage.image =  UIImage(named: "placeholder")

            getImage(link: cell.product?.productImage ?? "", completion: {(newImage) in



                DispatchQueue.main.async {

                    if self.productsImages.first(where: { $0.link == newImage.link}) == nil

                    {

                        self.productsImages.append(ProductImage(link : newImage.link , image : newImage.image) )

                    }

                    if cell.product?.productImage == newImage.link{

                        cell.pImage.image = newImage.image

                    }

                }



            })

        }

}
