ios - Prevent Image Overlaps in Table View Cell -

in cellforrowatindexpath method have following code.

    var cell = tableview.dequeuereusablecellwithidentifier("media item", forindexpath: indexpath) mediaitemtableviewcell      let mediaitem = tweet!.media[indexpath.row]      let imagedata = nsdata(contentsofurl: mediaitem.url)      if imagedata != nil {         cell.mediaimage = uiimage(data: imagedata!)     } else {         cell.mediaimage = nil     }      return cell 

when run code image overlaps on tableviewcell.

i love have image become thumbnail size , not overlap bounds of tableviewcell. best way approach this? i've tried resizing image image still becomes clipped. thanks.

have marked aspect-fit in uiimage , clipsubviews on mediaitemtableviewcell class in interfacebuilder? (attached image).
