ios - Table row action to segue with indexPath row

Question

So I have a table view and a Custom VC. then I have an object exercises with detailImage as property. How can I get the indexPath.row from the table row action into my prepareForSegue function?

this returns nil: self.tableView.indexPathForSelectedRow

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "detailsSegue" {            
          if let indexPath = self.tableView.indexPathForSelectedRow {
             let destinationController = segue.destinationViewController as! DetailViewController
             print(self.exercises[indexPath.row].image)
             destinationController.detailImage = self.exercises[indexPath.row].image
             print ("send")
           }
    }
}

Instead of this in your code:

if let indexPath = self.tableView.indexPathForSelectedRow {

Try this:

if let indexPath = self.tableView.indexPathForSelectedRow() {
