Okay so here is the problem I'm running into:

I am attempting to switch from one `viewController` that I named `MenuViewController` which contains my menu (obviously). I have a separate `viewController` named `ViewController` that contains my `mapView`. I would like to be able to double finger `swipe left` from my `MenuViewController` over to my `mapView`. 

I'm not exactly sure where to start. 

Also, I am using xib files, and not the storyboard. Running iOS 6.
