Getting Index Integer From indexPath From Cell in Swift

Here are two functions.

The first function is where I am giving gestures to each cell in my


I am trying to send over the indexPath from this function to my second function when ever a double tap gesture event occurs. So my action calls

In my second function im trying to use the sender to get the
of the cell. I am able to get an
that, when logged, prints out "0xc000000000078016> {length = 2, path = 0 - 0}" when I double tap the first cell.

How do I get just the integer 0, when I tap the first cell?

All suggestions are welcomed. Thank you, everyone.

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as myViewCell

//adding single and double tap gestures for each cell
//ISSUE IS SENDING indexPath TO doubleTap FUNC
var gestureDoubleTap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "doubleTap:")
gestureDoubleTap.numberOfTapsRequired = 2

var gestureSingleTap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "singleTap")
gestureSingleTap.numberOfTapsRequired = 1

cell.imgView.image=UIImage(named: imageArray[indexPath.row])

return cell

func doubleTap(sender: UITapGestureRecognizer) {
var tapLocation = sender.locationInView(self.collectionView)
var indexPath:NSIndexPath = self.collectionView.indexPathForItemAtPoint(tapLocation)!

//var cell = self.collectionView.cellForItemAtIndexPath(indexPath)

NSLog("double tap")
NSLog("%@", indexPath)

//NSLog("%@", cell!)
//name = imageArray[indexPath]
//self.performSegueWithIdentifier("segue", sender: nil)

You could use the following to retrieve the index from the touch point as shown in your code:

var indexPath : NSIndexPath = self.collectionView.indexPathForItemAtPoint(tapLocation)!

let rowNumber : Int = indexPath.row

//use rowNumber as index for your array.


let index : Int = (indexPath.section * maxCol) + indexPath.row
