Return to main view controller when app goes in background

In my app I have tree view controllers, when the app enters background I want the app to get back to the main view controller. My app is a single application without


I know that I have to implement this inside:

func applicationWillResignActive(application: UIApplication) {


but I am not sure how to tell the app to return to the main view controller.

How can I do this?


I have made a small example that takes the app to the main view controllers when enters background.
The first Time it goes background the app works fine after I start to get a warning. How can I resolve the warning?


Here is your fixed project. The catch was to just to set the rootViewcontroller of Appdelegate's window like this when the application goes to background

 let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
 let mainViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("MainView") as! ViewController
 let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
 appDelegate.window?.rootViewController = mainViewController
