xcode - Value of type 'CollectionViewCell' has no member 'imageView' -

my build fails due following 2 errors

1. value of type explorecollectionviewcell has no member 'imageview'
2. value of type explorecollectionviewcell has no member 'titlelabel'

i can't figure out change causing failure or how fix without redoing whole project.

func collectionview(collectionview: uicollectionview, cellforitematindexpath indexpath: nsindexpath) -> uicollectionviewcell {      let cellapt = collectionview.dequeuereusablecellwithreuseidentifier("cellapt", forindexpath: indexpath) as! explorecollectionviewcell      cellapt.imageview?.image = self.imagearray[indexpath.row]     cellapt.titlelabel?.text = self.condocells[indexpath.row]     cellapt.setneedslayout()      return cellapt } 

storyboard

explorecollectionviewcell should have properties codes below:

class explorecollectionviewcell: uicollectionviewcell {     @iboutlet weak var imageview: uiimageview!     @iboutlet weak var titlelabel: uilabel!      ... }
