Switch from UIViewController to other ViewController which is inside navigationController

I have the following views:

TabBarController includes (MapViewController, NavigationController) Navigation Controller includes the DetailViewController which is needed to switch to. Code below is used in the MapViewController.

Right now my code:

    let eventDetailViewController : EventDetailViewController = self.storyboard?.instantiateViewControllerWithIdentifier("EventDetail") as EventDetailViewController
    eventDetailViewController.event = event
    self.showViewController(eventDetailViewController, sender: self)

This works, but the navigation controller is no where insight (I cannot go to firstviewcontroller for example).

How to fire this code via the navigation controller?

Below is a screenshot of the storyboard. From left to right: TabbarController -> NavigationController and MapController. NavigationController -> EventController. The most righter view is the EventDetailView Storyboard

So, from your MapView, self.tabBarController will point to the tabBarController. It looks from your storyboard like the Navigation Controller is the first tab, so will be at index 0 in the tabBarController's viewControllers property. So you should be able to do the following:

let eventDetailViewController : EventDetailViewController = self.storyboard?.instantiateViewControllerWithIdentifier("EventDetail") as EventDetailViewController
eventDetailViewController.event = event
let navController : UINavigationController = self.tabBarController.viewControllers[0] as UINavigationController
navController.pushViewController(eventDetailViewController, animated:YES)
self.tabBarController.selectedIndex = 0

I'm still learning Swift, so you may have to sort some optionals/unwrapping out - but I hope you get the gist.
