How to show custom nested lists in iOS

问题

I want to show a list in iOS that itself will contain a list. For example I want to create a day wise task list in which the day and task are dynamic.So outer list is DAY LIST and inner list would be TASK LIST.Also want to handle the click on TASKS. How can I achieve this in iOS, have tried using Table Views but cannot achieve it since I want to show nested list.In short I want to show a list of list in iOS.

                cell = tblViewForHome.dequeueReusableCell(withIdentifier: "FeaturedLocationsCell") as! FeaturedLocationCellClass

                   return cell
        }

        func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

            //It should be greater than your collectionViewCell's size
            return 300.0

        func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize{
