SWRevealViewController toggle not working with custom Navigation Bar Button - ios

Question

I am using SWRevealViewController to show a side menu in Swift 2.0 I have downloaded the files from GitHub, created the bridging header and connected segues correctly. I am creating a custom button but the action "reveal toggle" is not firing. Where am I making a mistake?
super.viewDidLoad()
self.navigationController?.navigationBar.topItem?.title = "DASHBOARD"
self.navigationController!.navigationBar.tintColor = UIColor.whiteColor()
self.navigationController!.navigationBar.titleTextAttributes =
[NSForegroundColorAttributeName: UIColor.whiteColor()]
self.navigationController!.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "Teko-Regular", size: 26)!]
self.navigationController?.navigationBar.barTintColor = UIColor.redColor()
let btnName = UIButton()
btnName.setImage(UIImage(named: "LeftNavItem"), forState: .Normal)
btnName.frame = CGRectMake(0, 0, 20, 20)
let leftBarButton = UIBarButtonItem()
leftBarButton.customView = btnName
self.navigationItem.leftBarButtonItem = leftBarButton
if self.revealViewController() != nil {
//print(self.revealViewController())
leftBarButton.target = self.revealViewController()
leftBarButton.action = Selector("revealToggle:")
self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
The gesture recognizer is firing properly, but not the "revealToggle:" What's the mistake?

Answer 1

class Name: SWRevealViewControllerDelegate
override func viewDidLoad() {
super.viewDidLoad()
self.revealViewController().delegate = self
}

Answer 2

I was facing same issues using SWRevealViewController.
Solution :**After Login i was calling dashboard screen before But now
i replaced with SWrevealviewcontroller like below code.that's it now working fine
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let viewController1 =
storyboard.instantiateViewController(withIdentifier: "SWRevealViewController") as! SWRevealViewController
self.present(viewController1, animated: true,completion: nil)
*Add below code in viewdidload() method
if revealViewController() != nil {
menuoutlet.target = self.revealViewController()
menuoutlet.action = #selector(SWRevealViewController.revealToggle(_:))
self.view.addGestureRecognizer(revealViewController().panGestureRecognizer())
self.revealViewController().rearViewRevealWidth = 240
}
Menu button action code
#IBAction func menu(_ sender: Any) {
let btntitle = (sender as AnyObject).currentTitle!
self.revealViewController().rearViewController.performSegue(withIdentifier: btntitle!, sender: self.revealViewController().rearViewController)
}
