Segue not getting selected row number

Question

I am passing data from a table view controller to a detail view. I tried using indexPath.row directly in my prepareForSegue method, however it displays

Answer 1

The best way to do this kind of thing is not to use the delegate.

Updated Swift 4+

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let selectedIndex = tableView.indexPath(for: sender as! UITableViewCell)
    // Do your stuff with selectedIndex.row as the index
}

Original Answer

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    let selectedIndex = self.tableView.indexPathForCell(sender as UITableViewCell)
    // Do your stuff with selectedIndex.row as the index
}

Answer 2

//In didSelectRowAtIndexPath, you use this code:

func tableView(tvMain: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        self.performSegueWithIdentifier("yourSegueName", sender: nil)

    }

//And prepareForSegue to get IndexPath and send your value

override func prepareForSegue(segue: UIStoryboardSegue,
        sender: AnyObject!){

            let indexPath : NSIndexPath = self.yourTableView.indexPathForSelectedRow()!
            //make sure that the segue is going to secondViewController
            let detailsVC = segue.destinationViewController as DetailTableViewController
            detailsVC.selectedPersonName = "\(people[indexPath.row])"

    }

Answer 3

Swift 3 update:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let selectedIndex = tableView.indexPath(for: sender as! UITableViewCell)!
    // Do your actual preparing here...
}
