Update Rows after .Delete in TableView

Good day!

I have a TableViewController with EditingStyle:

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)

if editingStyle == .delete
machine.formulas.remove(at: indexPath.row)
machine.saveFormulas()
tableView.deleteRows(at: [indexPath], with: .fade)
tableView.reloadData()

else if editingStyle == .insert
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view




Each cell has a label with row number. If i .reloadData() as in the code above it breaks the .deleteRows() animation. I tried different variations, with beginUpdates() and .reloadRows(), nothing gave the required result. I think there is a simple solution for that, but I can't figure it out.

EDIT:

Edited code so the item is removed from array at first then from tableView.

EXAMPLE:

If you delete row #5, how do you .reloadData() so everything is in order. I mean there won't be 1-2-3-4-6-7-8-9-10. And how do you reload it without breaking .Delete animation?

.reloadData()

.deleteRows

Simply remove from the dataSource and Delete the row can do, No need to reload it.

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)

if editingStyle == .delete
machine.formulas.remove(at: indexPath.row)
machine.saveFormulas()
tableView.deleteRows(at: [indexPath], with: .fade)
self.perform(#selector(reloadTable), with: nil, afterDelay: 2)

else if editingStyle == .insert
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view



@objc func reloadTable()
self.tableView.reloadData()



Try and share results.

override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath)

if editingStyle == .delete
machine.formulas.remove(at: indexPath.row)
machine.saveFormulas()
tableView.deleteRows(at: [indexPath], with: .fade)
self.perform(#selector(reloadTable), with: nil, afterDelay: 2)




@objc func reloadTable()
DispatchQueue.main.async //please do all interface updates in main thread only
self.tableView.reloadData()
