Unable to add dynamic data in expandable tableview iOS swift?

Question

I'm new to iOS development I'm trying to implement expandable table with dynamic data which comes from server. I'm using https://github.com/amratab/ThreeLevelAccordian this expandable table view.

In this library they added statically like below code.

   cells.append(TLAHeaderItem(value: "Bathroom" as AnyObject, imageURL: "bathroom_grey_32.png"))
        cells.append(TLACell(value: "Shower" as AnyObject))
        cells.append(TLASubItem(value: "Shower pores should be cleaned effectively by brushing." as AnyObject))
        cells.append(TLACell(value: "Tap" as AnyObject))
        cells.append(TLASubItem(value: "Taps must be washed with soap and all the salt removed." as AnyObject))
        cells.append(TLACell(value: "Toilet" as AnyObject, imageURL: "toilet_grey_32.png"))
        cells.append(TLASubItem(value: "Should be made stains and germs free." as AnyObject))

        cells.append(TLAHeaderItem(value: "Bedroom" as AnyObject, imageURL: "bedroom_grey_32.png"))
        cells.append(TLACell(value: "Bed" as AnyObject))
        cells.append(TLASubItem(value: "Remove all the dust." as AnyObject))
        cells.append(TLACell(value: "Dressing" as AnyObject))


        cells.append(TLAHeaderItem(value: "Kitchen" as AnyObject, imageURL: "kitchen_grey_32.png"))
        cells.append(TLACell(value: "Utensils" as AnyObject))
        cells.append(TLASubItem(value: "There are many type of utensils like tongs, rolling pin, pan, non stick pans. Wash them all." as AnyObject))
        cells.append(TLACell(value: "Sink" as AnyObject))
        cells.append(TLASubItem(value: "Clean the sink" as AnyObject))

in cellforrowindexpath they are using like this.

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let item = self.cells[(indexPath as NSIndexPath).row]
        let value = item.value as? String
        if let cell = tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) {
            cell.textLabel?.text = value
            let label = cell.textLabel!
            cell.imageView?.image = nil
            if let headerImage = item.imageURL, let image = UIImage(named: headerImage) {
                cell.imageView?.image = image
            }
            if let accessoryView = accessory(for: indexPath, and: .expand) {
                cell.accessoryView = accessoryView
            } else {
                cell.accessoryType = UITableViewCellAccessoryType.none
                cell.accessoryView = nil
            }

            if let _ = item as? TLAHeaderItem {
                if let headerFont = headerCellFont {
                    cell.textLabel?.font = headerFont
                }


                if let headerCellBackgroundColor = self.headerCellBackgrondColor {
                    cell.backgroundColor = headerCellBackgroundColor
                }
                if let headerCellTextColor = self.headerCellTextColor {
                    cell.textLabel?.textColor = headerCellTextColor
                }
            } else if (item as? TLASubItem != nil) {
                if isMultiline {
                    label.lineBreakMode = NSLineBreakMode.byWordWrapping
                    label.numberOfLines = 0
                    label.sizeToFit()
                }

                cell.accessoryView = nil
                cell.accessoryType = UITableViewCellAccessoryType.none

                if let subItemCellBackgrondColor = self.subItemCellBackgrondColor {
                    cell.backgroundColor = subItemCellBackgrondColor
                }
                if let subItemCellTextColor = self.subItemCellTextColor {
                    cell.textLabel?.textColor = subItemCellTextColor
                }
                if let subItemCellFont = self.subItemCellFont {
                    cell.textLabel?.font = subItemCellFont
                }
            } else {
                if let itemCellBackgrondColor = self.itemCellBackgrondColor {
                    cell.backgroundColor = itemCellBackgrondColor
                }
                if let itemCellTextColor = self.itemCellTextColor {
                    cell.textLabel?.textColor = itemCellTextColor
                }
                if let itemCellFont = self.itemCellFont {
                    cell.textLabel?.font = itemCellFont
                }
            }

            return cell
        }
        return UITableViewCell()
    }

instead of adding statically i want to add dynamically array of data. to the cell.

Example:

cell.textLabel?.text = self.tableViewData[indexPath.row]
