Answer 1

The following code should work well for you :

 override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "showDetailsSegue" {

          let detailsVC = segue.destinationViewController as! DetailsViewController
          let cell = sender as! StampsCollectionViewCell
          let indexPaths = self.couponsCollectionView.indexPathForCell(cell)
          var thisCoupon = self.userCoupons[indexPaths!.row] as UserCoupons
          detailsVC.userCoupon = thisCoupon
          detailsVC.pinArray = self.pinArray
          detailsVC.userStamp = self.userStamps[indexPaths!.row]

    }

}

You can try this:

override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    let cell = collectionView.cellForItemAtIndexPath(indexPath)
    self.performSegueWithIdentifier("showDetailsSegue", sender: cell)
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "showDetailsSegue" {
        let detailsVC: DetailsViewController = segue.destinationViewController as! DetailsViewController
        let cell = sender as! StampsCollectionViewCell
        let indexPath = self.collectionView!.indexPathForCell(cell)
        var thisCoupon = self.userCoupons[indexPath.row] as UserCoupons
        detailsVC.userCoupon = thisCoupon
        detailsVC.pinArray = self.pinArray
        detailsVC.userStamp = self.userStamps[indexPath.row]

    }

}

Try this:

let cell = sender as StampsCollectionViewCell
let indexPath = self.collectionView!.indexPathForCell(cell)

And your code will be:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) 

{
    if segue.identifier == "showDetailsSegue" {
        let detailsVC: DetailsViewController = segue.destinationViewController as! DetailsViewController
        let cell = sender as StampsCollectionViewCell
        let indexPath = self.collectionView!.indexPathForCell(cell)
        var thisCoupon = self.userCoupons[indexPath.row] as UserCoupons
        detailsVC.userCoupon = thisCoupon
        detailsVC.pinArray = self.pinArray
        detailsVC.userStamp = self.userStamps[indexPath.row]

    }

}

Hope it will work.
