How to set root view controller?

Question

I want to make slide out menu. For this I have to create UINavigationViewController which will controlMenuViewController(Table View) and ProfileViewController(Content View)

I want to set UINavigationViewController like a rootViewController, for this I wrote this code in AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

let nav1 = UINavigationController()
        let mainView = MainViewController(menuViewController: nil, contentViewController: nil) //ViewController = Name of your controller
        nav1.viewControllers = [mainView]
self.window?.rootViewController = nav1

        self.window?.makeKeyAndVisible()

        return true
    }

MainViewController is my UINavigationViewController.

But here I have error

nil is not compatible with expected argument type 'UIViewController'

What I should do?

Actually its UINavigationViewController, but i import one library and now its look like class MainViewController:ENSideMenuNavigationController, ENSideMenuDelegate { — Zhandos.Nurakhmetov

You pass nil here: MainViewController(menuViewController: nil, contentViewController: nil) instead of some view controllers. That's probably the reason it doesn't compile.
You embed your MainViewController instance, which is already UINavigationController, into another one UINavigationController. That looks wrong too.

The second point explain your line: MainViewController is my UINavigationViewController.

Here is an example:

LoginViewController *loginController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"loginController"]; //or the homeController
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:loginController];
self.window.rootViewController = navController;`

This error means you can't set menuViewController and contentViewController to nil, they are not optional
