swift splitview controller default cell

Question

I am currently working on a project with a split view controller using swift in xcode6.

I currently have it so that when the app loads it remembers which cell you previously had selected and will "select" that cell. However when the cell is selected it doesn't initiate the segue to the detail view controller loading that cells related information.

This is my master view controller code, wondering what I can add to initate the segue for the selected cell when the app loads?

class MasterViewController: UITableViewController {

var detailViewController: DetailViewController? = nil
var titles = [String]()
var ageGroups = [String]()
var danceForms = [String]()
var danceDivisions = [String]()
var danceCategories = [String]()
var routineIds = [Int]()



override func awakeFromNib() {
    super.awakeFromNib()
    self.clearsSelectionOnViewWillAppear = false
    self.preferredContentSize = CGSize(width: 320.0, height: 600.0)
}

override func viewDidLoad() {
    super.viewDidLoad()
   self.navigationItem.setRightBarButtonItems([rightAddBarButtonItem,rightSearchBarButtonItem], animated: true)





    let query = PFQuery(className: "Schedule")
    query.orderByAscending("routineId")
    query.whereKey("eventId", equalTo: 16)
    query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in

        if let objects = objects {


            for object in objects {

                self.titles.append(object["title"] as! String)
                self.ageGroups.append(object["ageGroup"] as! String)
                self.danceForms.append(object["danceForm"] as! String)
                self.danceDivisions.append(object["danceDivision"] as! String)
                self.danceCategories.append(object["danceCategory"] as! String)
                self.routineIds.append(object["routineId"] as! Int)



                dispatch_async(dispatch_get_main_queue(), { () -> Void in
                    self.tableView.reloadData()
                    var returnValue: Int? = NSUserDefaults.standardUserDefaults().objectForKey("selectedCell") as? Int
                    if let value = returnValue{

                    }
                    else{
                        returnValue = 1;
                    }
                    if  returnValue! > self.routineIds.count{
                        returnValue = 1;
                    }
                    let rowToSelect:NSIndexPath = NSIndexPath(forRow: returnValue!-1, inSection: 0);  //slecting 0th row with 0th section
                    self.tableView.selectRowAtIndexPath(rowToSelect, animated: true, scrollPosition: UITableViewScrollPosition.None);

                })




            }


        }
    }

You can initiate a segue manually with the performSegueWithIdentifier method on UIViewController.

// in your dispatch_async block:
self.performSegueWithIdentifier("showDetail", self)
