using 2 gesture recognizers in storyboard mode in Xcode 6.1 (swift)

hello! I've been experimenting with using custom animations for segues between view controllers. Adding a the swipe gesture recognizer straight to the storyboard works great as a segue. However, Xcode tells me in order to add a left AND right gesture, I need to drag in 2 gesture recognizers. However, the segue only goes under 1 of them.

So I guess my question is, How can I use 2 gesture recognizers (in storyboard mode) on ONE view controller???

In Xcode 6.1 on my Mac, it lets me add 2 UISwipeGestureRecognizers just fine. If you're asking how to perform the same segue with both UISwipeGestureRecognizers, what I'd do is make sure you set the Identifier for the segue you want to execute, then make an @IBAction for the UISwipeGestureRecognizer that doesn't have the segue connected to it. If that @IBAction's function, just call the performSegueWithIdentifier function, like this:

performSegueWithIdentifier("YourSegueIdentifierHere", sender: nil)

You could also set the sender: to an @IBOutlet of the UISwipeGestureRecognizer that fired the @IBAction, but then you have to go through the trouble of setting up that @IBOutlet, so I just think it's easier to set it to nil

I can add 2 just fine.... but only 1 direction works at a time. For example, I have 1 GR set to swipe left that will segue to the next view controller. But when I add another GR to swipe right to either exit that view or segue to a different view controller, nothing happens.

i havne't done any coding by the way, this is all done on the main storyboard.
