SWRevealViewController side menu is not working in swift 3 - ios

Question

I am using SWRevealViewController for side menu functionality. Its working fine but whenever I have added the following code in didFinishLaunchingWithOptions method. side menu is not working for first time launch.
How to solve this problem??
this is my Code :
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// UserDefaults.standard.synchronize()
// IQKeyboardManager.sharedManager().enable = true
self.window = UIWindow(frame: UIScreen.main.bounds)
guard UserDefaults.standard.object(forKey: "IsFirstTime") != nil else {
UserDefaults.standard.set(true, forKey: "IsFirstTime")
self.window = UIWindow(frame: UIScreen.main.bounds)
let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "LaunchViewController") as! LaunchViewController
let navigationController = UINavigationController.init(rootViewController: viewController)
self.window?.rootViewController = navigationController
self.window?.makeKeyAndVisible()
return true
}
self.window = UIWindow(frame: UIScreen.main.bounds)
let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "SWRevealViewController") as! SWRevealViewController
// let navigationController = UINavigationController.init(rootViewController: viewController)
self.window?.rootViewController = viewController
self.window?.makeKeyAndVisible()
return true
}
Thank you

Here you are making LaunchViewController initial VC on first launch. That's why it is not working at first time.
To use SWRevealViewController you need two view controller, one is front view controller which you want to show first time and second is for drawer which maybe tableViewController that contains all other view controller. To add SWRevealViewController call openDrawer() in AppDelegate.
func openDrawer() {
let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
let drawerVC = storyboard.instantiateViewController(withIdentifier: "idDrawerVC") as! RearVC
let dashboardVC = storyboard.instantiateViewController(withIdentifier: "idFrontVC") as! FrontVC
let frontNavigationController = UINavigationController(rootViewController: dashboardVC)
let revealViewController = SWRevealViewController(rearViewController: drawerVC, frontViewController: frontNavigationController)
revealViewController?.delegate = self
revealViewController?.view.backgroundColor = .clear
revealViewController?.modalTransitionStyle = .crossDissolve
window?.rootViewController = revealViewController
}
