pushViewController not working

Question

I am new to ios with swift and swrevealviewcontroller. i faceing a problem! in my slide menu (scene TableViewController Two blue line draw) each row when selected then should be open particuler scene (View controller) but unfortunatly it is not open . there have no error and didselectRowAt fire when i select row from the table but pushViewController not working .

  func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        let dvcStoryBordId = menuViewIds[(indexPath.row - 1 )]

        let viewController = storyboard?.instantiateViewController(withIdentifier: dvcStoryBordId )

        self.navigationController?.pushViewController(viewController!, animated: true)
    }

Story Board

do i miss anything ? is it correct way ? self.

UPDATE :

self.navigationController is nil . is there any alternative ? or without navigation

Update:

Storyboard Id

menuViewIds = ["shareWithFriends","deliveryTracking", "controls", "support","myAccount"]

Run time view

Please debug and check self.navigationController is not null. — Vikram Biwal, Nov 22 '16 at 06:56
@user4887505 self.navigationController is nil . what should i do — cristan lika, Nov 22 '16 at 07:10
from the image of your storyboard it seems that your Slide TableViewController (the one with the blue lines) is not wrapped in a navigation controller, so therefore the navigationController is `nil`. So either you could wrap/embed it in a navigationController or you could just use `present` on the Slide TableViewController. — pbodsk, Nov 22 '16 at 07:22
Note that `IndexPath` is zero-based, so double check if `menuViewIds[(indexPath.row - 1 )]` is really what you meant. — zisoft, Nov 22 '16 at 07:59

Try this:

   func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

         let dvcStoryBordId = menuViewIds[(indexPath.row - 1 )]
         let viewController = storyboard?.instantiateViewController(withIdentifier: dvcStoryBordId )
         var navigationController = UIApplication.sharedApplication().keyWindow?.rootViewController as! UINavigationController
         navigationController?.pushViewController(viewController!, animated: true)

   }

Could not cast value of type 'LifeFast.ViewController' (0x10e127910) to 'UINavigationController' (0x1109adf18). – cristan lika Nov 22 '16 at 10:11
according to image, i think first row last image your menu Controller if yes then can you access viewController object in your method “didSelectRowAt indexPath” ? – Vikram Biwal Nov 22 '16 at 11:20
no! second row 1st image . please check my update section – cristan lika Nov 22 '16 at 19:57

Try This:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

         let dvcStoryBordId = menuViewIds[indexPath.row]
         let viewController = storyboard?.instantiateViewController(withIdentifier: dvcStoryBordId )
         let vc = windowRootViewController() as! SWRevealViewController
         let nvc = vc.frontViewController as! UINavigationController
         nvc.pushViewController(viewController, animated: true)
   }

WindowRootVC() :

func windowRootViewController() -> UIViewController {
    return (UIApplication.shared.delegate?.window??.rootViewController)!
}

pushViewController not working
