Here is my codes when expand section: 

let lastScrollOffset = self.tableView.contentOffset
self.tableView.beginUpdates()
self.tableView.insertRows(at: indexPathsForSection(section: section), with: .none)//reloadSections([section], with: .fade)
self.tableView.endUpdates()
self.tableView.layer.removeAllAnimations()
self.tableView.setContentOffset(lastScrollOffset, animated: false)
let indexPath = IndexPath(row: NSNotFound, section: section)
self.tableView.scrollToRow(at: indexPath, at: .none, animated: true)

  • I'm sorry but can you explain the problem a bit better? Possibly with actual and expected behaviour? – Rikh May 26 '20 at 10:18
