Navigation rootViewController issue with HomeVC Sign out Button in Swift

I have home view controller with ENSideMenu for side menu and in home view controller i have sign out button. I have given ENSideMenu MyNavigationController as an is initial view controller in storyboard.

I want to show home first in app which is working fine but when i come from login to home then home is not responding.. once i sign out then again home is responding.

Here is my code:

in appdelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    let userId: String? = KeychainWrapper.standard.string(forKey: "Uid") 
    print("appdelegate userid \(userId)")
    if userId != nil{
        let mainStoryBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let homeVC = mainStoryBoard.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
        self.window!.rootViewController = homeVC
    }
    return true
}

in loginButton in LogInVC:

    let saveUserId: Bool = KeychainWrapper.standard.set(Uid ?? "", forKey: "Uid")
                print("the userid is \(saveUserId)")

                if (Uid?.isEmpty)!
                {
                    print("login fail")
                }
                else{

                    DispatchQueue.main.async {

                        let homeVC = self.storyboard?.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
                        let appDelagate = UIApplication.shared.delegate
                        appDelagate?.window??.rootViewController = homeVC
                    }
                }

in HomeVC:

  func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

    let nextViewController = self.storyboard?.instantiateViewController(withIdentifier: "MakePaymentViewController") as! MakePaymentViewController
    self.navigationController?.pushViewController(nextViewController, animated: true)
    let indexPathHome = indexPath.row
    print("home collectionItem indexpath \(indexPathHome)")

}


 @IBAction func signOutButton(_ sender: Any) {
    print("signout tapped")
    KeychainWrapper.standard.remove(key: "Uid")
 }

  @IBAction func sideMenuButton(_ sender: Any) {
    print("in side menu")
    toggleSideMenuView()
 }

I have given ENSideMenu MyNavigationController as an is initial view controller in storyboard.

I need homeVc to respond after coming from login. please help me to solve the issue.

You are using custom MyNavigationController with HomeViewController for navigation purposes - you already mention, that it is your initial view in storyboard. But... there are two other places, where you are loading HomeViewController without MyNavigationController:

1. AppDelegate

change loading HomeViewController:

let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
window?.rootViewController = mainStoryBoard.instantiateViewController(withIdentifier: "MyNavigationController")

2. LoginViewController

Change

let homeVC = self.storyboard?.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
let navigationController = UINavigationController(rootViewController: homeVC)

to

let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
let navigationController = mainStoryBoard.instantiateViewController(withIdentifier: "MyNavigationController")

Also, I have some advice for you:

1. Avoid ! in your code - this is straight way to crash your app. There are lot of other ways to deal with optionals
2. Avoid catching strong self in closures (like in LoginViewController, when you are changing your view to HomeVC). This cause retain cycle, which leads to memory leak.
3. Remove all not needed selfs - and when compilator tells you, that you need to add self - look at point 2) and add weak self instead of strong.
4. Remove compilator warnings - you already have 19 warnings, you can remove all of them in few minutes.
