Swift ios how get parsed data and assign it to a label

Question

I want to know how to get each name from the parsed json response in swift. I want to assign the name value of the reponse to cell.label.text based on my code cell.label.text = item.name. Label will automate depending on how many item.name , what I want is that it will automate depending on how many name there is from json response

 if indexPath.row == 0 {
     // get a reference to our storyboard cell
     let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "AddNewCell", for: indexPath as IndexPath) as! AddNewCollectionViewCell
     cell.backgroundColor = unselectedCellColor // make cell more visible in our example project
     return cell
 } else {

     let index = IndexPath(row: (indexPath.row - 1), section: 0)

     let item = fetchedResultsController.object(at: index)

     // get a reference to our storyboard cell
     let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! GroceryItemCollectionViewCell
     cell.buttonDelegate = self
     cell.deleteButton.tag = indexPath.row - 1

     cell.label.text = item.name
     if item.isSelected {
          cell.backgroundColor = selectedCellColor
     } else {
          cell.backgroundColor = unselectedCellColor
     }
     return cell
}

Http request code:

responseString = Optional("[{"id":51,"name":"jelord","desc":"ako si jelord","reward":"1.00","sched":"2018-04-06T11:37:09+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":53,"name":"uuuuuu","desc":"uuuuu","reward":"8.00","sched":"2018-03-06T10:49:54+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":54,"name":"iiiii","desc":"oiii","reward":"67.00","sched":"2018-02-06T10:51:34+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":55,"name":"uuuu","desc":"uuuu","reward":"8.00","sched":"2018-03-06T10:52:55+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":57,"name":"uuuuuuuu","desc":"uuuuuu","reward":"8888.00","sched":"2018-04-06T11:54:16.431000+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":61,"name":"hhu","desc":"yhh","reward":"67.00","sched":"2018-02-06T13:45:09+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"},{"id":62,"name":"huhu","desc":"huu","reward":"8.00","sched":"2018-04-06T14:46:36.620000+08:00","parent":null,"child":null,"occurrence":{"name":"once"},"status":"created"}]")


code for getting the request.

var request = URLRequest(url: URL(string: "http://test.test:8000/api/v1/test/")!)

        request.httpMethod = "GET"
        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))")
                return
            }

            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))")
            }

            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(String(describing: responseString))")
        }
        task.resume()
