How do I collapse a cell when a new one is selected?

I've implemented it like the README says but it's giving me some assertion issues. I don't know if this is normal or not, I'm fairly new to cocoapods. When I would comment out the heightForRowAt it would not give me any assertion info. Is this something I need to fix or just keep it like this? Furthermore the pickers work as it should with no issues.

Full info:
[Assert] Attempted to call -cellForRowAtIndexPath: on the table view while it was in the process of updating its visible cells, which is not allowed. Make a symbolic breakpoint at UITableViewAlertForCellForRowAtIndexPathAccessDuringUpdate to catch this in the debugger and see what caused this to occur. Perhaps you are trying to ask the table view for a cell from inside a table view callback about a specific row? Table view: <UITableView: 0x14e818800; frame = (0 0; 375 812); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x280f51a40>; layer = <CALayer: 0x280103840>; contentOffset: {0, -88}; contentSize: {375, 325.33333333333337}; adjustedContentInset: {88, 0, 34, 0}; dataSource: <SkiMapMarker.AddTripsTVC: 0x14fe066b0>>

Code:

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        if let cell = tableView.cellForRow(at: indexPath) as? AUPickerCell {
            return cell.height
        }else if indexPath.section == 0 && indexPath.row == 1 {
            return 200
        }else{
            return super.tableView(tableView, heightForRowAt: indexPath)
        }
    }

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
 if indexPath.section == 0 {
            if indexPath.row == 0{
                let cell = tableView.dequeueReusableCell(withIdentifier: "GebiedNaam", for: indexPath) as! GebiedNaam

                cell.gebiedNaamLabel.text = gebiedNaam

                return cell
            }else{
                let cell = tableView.dequeueReusableCell(withIdentifier: "GebiedKaart", for: indexPath) as! GebiedKaart

                cell.imageViewCell.image = kaartAfbeelding

                return cell
            }
        }else{
            if indexPath.row == 0{
                let cell = AUPickerCell(type: .date, reuseIdentifier: "DatumStartPicker")
                cell.datePickerMode = .date
                cell.leftLabel.text = "Start:"
                cell.dateStyle = .medium
                cell.timeStyle = .none
                cell.delegate = self

                return cell
            }else {
                let cell = AUPickerCell(type: .date, reuseIdentifier: "DatumEindePicker")
                cell.datePickerMode = .date
                cell.dateStyle = .medium
                cell.timeStyle = .none
                cell.leftLabel.text = "Einde:"
                cell.delegate = self


                return cell
            }
        }
    }

Unless the Picker is closed, the data contained in the right labels of the cells below are deleted.
Can you help me to resolve?

I changed this to the AUPickerCell.swift class to increase the height of the list when opening the picker:

public func selectedInTableView(_ tableView: UITableView) {
let unexpandedHeightList = CGFloat(Double(tableView.numberOfRows(inSection: 0)) * 29.5)
let expandedHeightList = unexpandedHeightList + picker.bounds.height
let heightList = !self.expanded ? expandedHeightList : unexpandedHeightList
print(heightList)
let expandedFrame = CGRect(x: tableView.frame.origin.x,
y: tableView.frame.origin.y,
width: tableView.bounds.width,
height: heightList)
print(expandedFrame.height)
if !expanded {
rightLabelTextColor = rightLabel.textColor
}
expanded = !expanded
UIView.transition(with: rightLabel, duration: 0.15, options: .transitionCrossDissolve , animations: { [unowned self] in
tableView.frame = expandedFrame
self.rightLabel.textColor = self.expanded ? self.tintColor : self.rightLabelTextColor
})
tableView.beginUpdates()
tableView.endUpdates()
}

It would be cool to add a gif showing the use of your library. You can use this as an example
