  // FETCH MAGAZINE
func fetchDatafromServer(){

    guard let url = URL(string: "https://www.pcbuyersguide.com.ph/wp-content/mobileapp/pcbg_magazine_data.php") else {return}
    URLSession.shared.dataTask(with: url) { (data, res, err) in

        guard let data = data else {return}

        do{
            let articles = try JSONDecoder().decode([Root].self, from: data)

            for info in articles {

                self.magazine_title.append(info.server_response[1].magazine_title)


            }

            DispatchQueue.main.async {

                self.collectionView?.reloadData()
            }
        }
        catch let jsonErr{

            print(jsonErr)
        }

        }.resume()
}

Answer 1

You are saying decode([Root].self... , as if your JSON were an array of Root. But it is not an array of Root. It is a Root. Say decode(Root.self .

Then change

for info in articles

To

for info in articles.server_response

That is the array.
