Refresh certain row of UITableView based on Int in Swift

You can create an NSIndexPath using the row and section number then reload it like so:

let indexPath = NSIndexPath(forRow: rowNumber, inSection: 0)tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Top)

In this example, I've assumed that your table only has one section (i.e. 0) but you may change that value accordingly.

Update for Swift 3.0:

let indexPath = IndexPath(item: rowNumber, section: 0)tableView.reloadRows(at: [indexPath], with: .top)

For a soft impact animation solution:

Swift 3:

let indexPath = IndexPath(item: row, section: 0)tableView.reloadRows(at: [indexPath], with: .fade)

Swift 2.x:

let indexPath = NSIndexPath(forRow: row, inSection: 0)tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)

This is another way to protect the app from crashing:

Swift 3:

let indexPath = IndexPath(item: row, section: 0)if let visibleIndexPaths = tableView.indexPathsForVisibleRows?.index(of: indexPath as IndexPath) {    if visibleIndexPaths != NSNotFound {        tableView.reloadRows(at: [indexPath], with: .fade)    }}

Swift 2.x:

let indexPath = NSIndexPath(forRow: row, inSection: 0)if let visibleIndexPaths = tableView.indexPathsForVisibleRows?.indexOf(indexPath) {   if visibleIndexPaths != NSNotFound {      tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)   }}

In Swift 3.0

let rowNumber: Int = 2let sectionNumber: Int = 0let indexPath = IndexPath(item: rowNumber, section: sectionNumber)self.tableView.reloadRows(at: [indexPath], with: .automatic)

byDefault, if you have only one section in TableView, then you can put section value 0.
