ios - prepareForSegue UICollectionView not working (swift) -


i’ve tried push segue using uicollectionview (show image form masterview deatilview) not working. xcode doesn’t show error message. what’s wrong code. need advice.

override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {       if segue.identifier == "showdetail" {       if let indexpath = self.collectionview?.indexpathforcell(sender as! uicollectionviewcell) {          let detailvc = segue.destinationviewcontroller as! detailmenuviewcontroller              detailvc.picfood = self.collection[indexpath.row]
  • collection empty array data form json
  • [title = self.namefood.title], working in detailmenuviewcontroller.swift not image on code above.

you need add uicollecitonviewdelegate

func collectionview(collection: uicollectionview, selecteditemindex: nsindexpath)  {    self.performseguewithidentifier("showdetail", sender: self) }

after add 

override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {     if segue.identifier == "showdetail" {           if let indexpath = self.collectionview?.indexpathforcell(sender as! uicollectionviewcell) {              let detailvc = segue.destinationviewcontroller as! detailmenuviewcontroller                  detailvc.picfood = self.collection[indexpath.row]           }     } }
