Cannot subscript value of type 'String' with an index of type 'NSIndexPath'

In the following code I am trying to populate a detail view from a tableView but keep getting that NSIndexPath error. Without the 'if let indexPath' and [indexPath] it only returns the first section in the dictionary.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        let wod = FilteredWodList[index]
        if segue.identifier == "showBenchmarkDetail" {
            let controller = segue.destinationViewController as? BenchmarkWODDetailView
            if let indexPath = self.tableView.indexPathForSelectedRow

            {
            controller?.nameText = wod.name![indexPath]
            controller?.descriptionText = wod.description![indexPath]
            controller?.exerciseText = wod.exercise![indexPath]
            }

Corrected the problem with the code below.

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

        if segue.identifier == "showBenchmarkDetail" {
            let controller = segue.destinationViewController as? BenchmarkWODDetailView
            if let indexPath = self.tableView.indexPathForSelectedRow

            {


                let wod = FilteredWodList[indexPath.row]
                controller?.nameText = wod.name ?? ""
                controller?.descriptionText = wod.description ?? ""
                controller?.exerciseText = wod.exercise ?? ""
            }
