    {

    if(UISwipeGestureRecognizerDirection.Left == recognizer.direction)
    {
     self.rightScrollBtnPressed(nil)
    }

func createDetailView()
    {
        scrollView.contentSize = CGSizeMake(CGFloat(320*(pageImages.count)), scrollView.frame.height)
        scrollView.showsHorizontalScrollIndicator = false
        scrollView.scrollEnabled = false
        scrollView.bounces = false

    let rightSwipe = UITapGestureRecognizer(target: self, action: Selector(handleProductGesture()))
    rightSwipe.direction = UISwipeGestureRecognizerDirection.Right
    rightSwipe.delegate = self

    view.addGestureRecognizer(rightSwipe)

    let leftSwipe = UITapGestureRecognizer(target: self, action: Selector(handleProductGesture()))
    leftSwipe.direction = UISwipeGestureRecognizerDirection.Left
    leftSwipe.delegate = self
    view.addGestureRecognizer(leftSwipe)

     next = indexNumber-1
    self.rightScrollBtnPressed(nil)

}

Line :- let rightSwipe = UITapGestureRecognizer(target: self, action: Selector(handleProductGesture())) — Gaurav Verma, Mar 16 '15 at 10:23

The issue is with your selector passing code. You need to specify the method names as string there, in your code you are trying to invoke it.

Change those to:

let rightSwipe = UITapGestureRecognizer(target: self, action: Selector("handleProductGesture:"))

let leftSwipe  = UITapGestureRecognizer(target: self, action: Selector("handleProductGesture:"))
