ios - Two table views in view controller: Swift -

i have uitableview prototype cells takes whole page. have uibutton on bottom should display pop-up static uitableview when tapped. i'm struggling account pop-up table view in cellforrowatindexpath.

func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {          let result: uitableviewcell          if tableview == self.tableview {              var cell = self.tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) as! uitableviewcell              cell.textlabel!.text = array[indexpath.row]              result = cell          } else if tableview == self.popuptableview {              var popupcell = self.popuptableview.dequeuereusablecellwithidentifier("popupcell", forindexpath: indexpath) as! uitableviewcell              popupcell.textlabel!.text = popuparray[indexpath.row]              result = popupcell          }          return result     } 

i'm getting error @ return result, variable 'result' used before being initialized, i'm declaring @ top. going wrong this?

you need have exhaustive choices. it's possible result never gets initialized because checks "if" , "else if". happens if tableview not either "self.tableview" or "self.popuptableview"?

the simple fix (if plan on having these two) change "else if" simple "else". way result initialized.
