Swift 2 passing data through segue from UIcollectionview (indexpath.row) - ios

Question

I'm trying to pass data (value of dict["IDD"] ) via segue.
(XCODE 7.2)
Here my code:
var arrRes = [[String:AnyObject]]()
var dict = [:]
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("imageCell", forIndexPath: indexPath) as! collectionViewCell
var dict = arrRes[indexPath.row]
let newPrice = dict["price"]!.stringByReplacingOccurrencesOfString(".", withString: ",")
cell.lblPrice.text = "€\(newPrice)"
cell.lblTitle.text = dict["title"] as? String
cell.lblBrand.text = dict["brand"] as? String
cell.lblIDD.text = dict["IDD"] as? String
cell.imageView!.image = UIImage(named: "loading.gif") //set placeholder image first.
dispatch_async(dispatch_get_main_queue()) {
cell.imageView!.downloadImageFrom(link: dict["image"] as! String, contentMode: UIViewContentMode.ScaleAspectFit) //set your image from link array.
}
return cell
}
But I don't kwon how to setup the performseguewithidentifier for segue
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if(segue.identifier == "homeDetailSegue")
{
let cell = sender as! UICollectionViewCell
let detailView = segue.destinationViewController as! dettaglio
let dict = arrRes[(self.myCollectionView.indexPathForCell(cell))!]
detailView.setnomeOggetto(arrRes["IDD"] as! String)
}
}
I have no problem with tableviews but this is my first time with collectionView
Could please someone help me?
Kind Regards
Thank You very Much

I tried the solution for your question and now I got it.Try below the solution.
Before that go to stroyborad click the destinationViewController(here detailViewController)
Then click Identity Inspector of the Right Navigation bar.
Once you click the you can see the Identity under Custom Class
No click Identity then give 'detailsVC' or whatever you want in Storyboard ID.
Now in CollectionViewDelegate Method
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath)
{
// handle tap events
print("You selected cell #\(indexPath.item)!")
let detailVC = self.storyboard?.instantiateViewControllerWithIdentifier("detailVC") as! DetailViewController
detailVC.passDataToLabel = String (indexPath.item )
print(detailVC.passDataToLabel)
self.navigationController?.pushViewController(detailVC, animated: true)
}
