if tableView.cellForRow(at: indexPath)?.accessoryType == UITableViewCell.AccessoryType.checkmark
tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCell.AccessoryType.none
//Line above occurs the error
checkedCategories.remove(at: indexPath.row)

tableView.cellForRow(at: indexPath)?.accessoryType = UITableViewCell.AccessoryType.checkmark

You always adding items in the end of array (so index of added item is checkedCategories.count - 1). But deleting by index of row.
So instead of row index, get index of added category and then remove by this index
if let index = checkedCategories.firstIndex(of: allcategories[indexPath.row])
checkedCategories.remove(at: index)
