ios - PFImageView not showing up in the window -

i'm trying hand @ parse snapchat clon , going fine, when have display images user pfimageview not showing up, have no idea no errors show no subview.

the offending part:

func checkformessages() {  if pfuser.currentuser()?.username != nil {      println("checking msgs")      var query = pfquery(classname: "image")     query.wherekey("recipientusername", equalto: pfuser.currentuser()!.username!)      var msgs = query.findobjects()      println("\(msgs?.count) \(pfuser.currentuser()!.username!) recipientusername")      var done  = false      if let msg = msgs as? [pfobject] {         msgreceived in msg {              if done == false {                  var imageview: pfimageview = pfimageview()                  imageview.file = msgreceived["image"] as? pffile                  imageview.loadinbackground({                      (photo, error) -> void in                       if error == nil {                          var displayedimage = uiimageview(frame: cgrectmake(0, 0, self.view.frame.width, self.view.frame.height))                          displayedimage.image = photo                          println(photo!.description)                          self.view.addsubview(imageview) //here should place in view                     }                 })                   done = true             }          }      }      println(msgs?.count) } else {      println("waiting user should not showing") } } 

check supporting files/parsestarterproject-bridging-header.h file , see whether it's missing following line:

#import <parseui/parseui.h> 

if so, sure add it.
