Receiver ... has no segue with identifier error

The code in question:

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

    tableView.deselectRowAtIndexPath(indexPath, animated: true)

    var card: String

    if (tableView == self.searchDisplayController?.searchResultsTableView){
        card = self.filtered[indexPath.row]
    }

    else{
        card = self.array[indexPath.row]
    }



    let destinationVC = SearchViewController()
    destinationVC.searchString = card
    destinationVC.performSegueWithIdentifier("ResultSegue", sender: self)

}

I'm trying to pass a string to another view when a cell in my table is selected. In the storyboard I named the segue identifier 'ResultSegue'.

What happens when I run my app is when I click a cell it loads the next view, without the variable I'm sending being updated, then if I go back and click on a new cell the app will crash and give me the titled warning.

I've tried running clean, and resetting the simulator as other threads have suggested, but nothing changes.

You should pass a the string in prepareForSegue function rather than didSelectRowAtIndexPath function.

Instead of using didSelectRowAtIndexPath as below:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "ResultSegue" {

        if let indexPath = self.tableView.indexPathForSelectedRow() {
            var card: String
            if (tableView == self.searchDisplayController?.searchResultsTableView) {
                card = self.filtered[indexPath.row]
            } else {
                card = self.array[indexPath.row]
            }
            (segue.destinationViewController as SearchViewController).searchString = card
        }
    }
}
