When the user is reordering their items and dragging on a cell, I want the cell to have a thin material as background. However, when the user isn’t dragging any cells, the background would be clear to allow the table view background to come through the cells.

I am unable to get this to work…

func tableView(_ tableView: UITableView, dragPreviewParametersForRowAt indexPath: IndexPath) -> UIDragPreviewParameters? {
        // Create a copy of the cell for drag preview
        guard let cell = tableView.cellForRow(at: indexPath) else { return nil }
        
        // Create a visual effect view with blur effect
        let blurEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .systemThinMaterial))
        blurEffectView.frame = cell.bounds
        
        // Create a preview parameters object
        let previewParameters = UIDragPreviewParameters()
        let previewView = UIView(frame: cell.bounds)
        previewView.addSubview(blurEffectView)
        previewParameters.visiblePath = UIBezierPath(roundedRect: previewView.bounds, cornerRadius: 0)
        previewParameters.backgroundColor = .clear
        
        return previewParameters
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        cell.backgroundColor = .clear
        let item = fetchedResultsController.object(at: indexPath)
        cell.contentConfiguration = UIHostingConfiguration {
            ItemRow(item: item)
        }
        return cell
    }
