UITableView internal inconsistency: _visibleRows and _visibleCells must be of same length

I'm currently trying to make a self sizing tableview (where the cells autosize to fit their inner view's autolayout).

One of the cells has a tableview in it. The idea is that the cell should be the size of the contentSize.height of the tableview.

I subclassed UITableView to accomplish this, and when the tableview loads, it looks great. However, this error gets spit out:

[Assert] UITableView internal inconsistency: _visibleRows and _visibleCells must be of same length. _visibleRows: {0, 4}; _visibleCells.count: 8, _visibleCells:

Additionally, when I try to scroll the tableview after this error there is very strange behavior and the tableview starts an infinite loop of layoutsubviews.

Any idea what this error means? I haven't been able to find anything substantial referencing this error on the internet. Thanks in advance!

If your view hierarchy of UITableView is something like this .

• UITableView
  • UITableViewCells --- One cell has UITableView Follow this step to resize

1.Use tableview delegate method

  func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {           tableView.estimatedRowHeight = 80.0         let modal = arrData[indexPath.row]         if modal.isTableViewCell {         let calculateTableViewHeight =          modal.arrInnerTableViewData.count * inner_cell_height           return calculateTableViewHeight         }        return UITableViewAutomaticDimension     } 

2.Disable the scroll of Inner tableView
