How to perform an action when Swipe Gesture Recogniser is used to go to another View in Swift

Here is my problem (on Xcode 6.0.1, coding in Swift, using iOS 7.1 and 8.0): I am going from one view to another using a Swipe Gesture Recogniser (with the Action Segue "present modally").

Before this I was using a button "next" to go from one view to another. I created an @IBAction for this button next that was performing, let say, a simple println("test").

@IBAction func nextPressed(sender: AnyObject) {
    println("test")
}

If I run my app, when I press the button Next, I go to the next view and "test" appears in the consol.

Now I do the same for a Swipe Gesture Recogniser, let say I create an @IBAction for the Swipe Gesture Recogniser (so I ctrl-click on the gesture icon next to the view controller icon at the top of the view, then drag into the code).

@IBAction func swipeGestureDone(sender: AnyObject) {
    println("test")
}

If I run my app, when I swipe on the screen, I go to the next view but the "test" does not appear in the consol. I cannot figure out how to execute a function when I use a Swipe to go from one view to another. It is apparently because there is no "Sent Events" for a Swipe Gesture Recogniser as for a Button. I don't know how to do it. Everything seems to be well connected in the Connection inspector though.

I have a similar problem with a UITapGestureRecognizer. Here are a couple of things I found as solutions. They have not worked in my case, but maybe they will fix your issue:

Try selecting the type of object a UISwipeGestureRecognizer instead of AnyObject. 

@IBAction func swipeGestureDone(sender: UISwipeGestureRecognizer) {
    println("test")  
}

Also make sure that your view recognises gestures by adding 

yourView.userInteractionEnabled = true

Set cancelsTouchesInView of the recognizer to true. It does what it says.
