ios - Swift segue from CollectionViewCell failing to display new view -

i'm trying load new view when cell in collectionview selected.

everywhere online says it's simple registering new view , navigation controller in storyboard, , ctrl + click dragging collectionviewcell new view.

having done this, code compiles , runs, no new view appears when click on cells. have missed?

the storyboard says there segue collectionview next view (identified correct name , all), i'm bit confused...

edit: here collectionview controller code, in case i've done in here that's causing problem. it's calendar page (as can tell code):

iboutlet weak var calendarcollection: uicollectionview! var collectionview: uicollectionview? let calendarcellidentifier: string = "calendarcell"  override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.     let layout: uicollectionviewflowlayout = uicollectionviewflowlayout()     layout.sectioninset = uiedgeinsets(top: 50, left: 10, bottom: 10, right: 10)     layout.itemsize = cgsize(width: 60, height: 60)     collectionview = uicollectionview(frame: self.view.frame, collectionviewlayout: layout)     collectionview!.datasource = self     collectionview!.delegate = self     collectionview!.registerclass(uicollectionviewcell.self, forcellwithreuseidentifier: calendarcellidentifier)     collectionview!.backgroundcolor = uicolor.blackcolor()     self.view.addsubview(collectionview!) }  // return collectionview cell @ indexpath func collectionview(collectionview: uicollectionview, cellforitematindexpath indexpath: nsindexpath) -> uicollectionviewcell {     let cell: uicollectionviewcell = collectionview.dequeuereusablecellwithreuseidentifier(calendarcellidentifier, forindexpath: indexpath) uicollectionviewcell     cell.backgroundcolor = uicolor.bluecolor()     return cell }  func collectionview(collectionview: uicollectionview, shouldhighlightitematindexpath indexpath: nsindexpath) -> bool {     return true }  func collectionview(collectionview: uicollectionview, numberofitemsinsection section: int) -> int {     return challengedurationdays } 

for similar problems, solved manually triggering segue using didselectitematindexpath method. don't think should have had this, perhaps misunderstood. either or it's bug. method added collectionviewcontroller in end looks this:

func collectionview(collectionview: uicollectionview, didselectitematindexpath indexpath: nsindexpath) {     performseguewithidentifier("dayviewsegue", sender: calendarcollection) }
