i have been writing today extension app, , have loading main apps core data database. seems working fine, can see core data information being loaded, i'm not getting cells displayed

the code have

override func numberofsectionsintableview(tableview: uitableview) -> int {     return self.fetchedresultscontroller.sections!.count }  override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     let sectioninfo = self.fetchedresultscontroller.sections![section] nsfetchedresultssectioninfo     return sectioninfo.numberofobjects }  var fetchedresultscontroller: nsfetchedresultscontroller {     if _fetchedresultscontroller != nil {         return _fetchedresultscontroller!         }         var instance = singleton.sharedinstance          let fetchrequest = nsfetchrequest()         // edit entity name appropriate.         let entity = nsentitydescription.entityforname("medicine", inmanagedobjectcontext: instance.moc)         fetchrequest.entity = entity         // edit sort key appropriate.         let sortdescriptor = nssortdescriptor(key: "active", ascending: false)         let sortdescriptors = [sortdescriptor]          fetchrequest.sortdescriptors = [sortdescriptor]          // edit section name key path , cache name if appropriate.         // nil section name key path means "no sections".         let afetchedresultscontroller = nsfetchedresultscontroller(fetchrequest: fetchrequest, managedobjectcontext: instance.moc, sectionnamekeypath: nil, cachename:nil)         afetchedresultscontroller.delegate = self         _fetchedresultscontroller = afetchedresultscontroller         var error: nserror? = nil         if !_fetchedresultscontroller!.performfetch(&error) {             abort()         }         return _fetchedresultscontroller! } var _fetchedresultscontroller: nsfetchedresultscontroller? = nil  override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) uitableviewcell     var med : medicine = self.fetchedresultscontroller.objectatindexpath(indexpath) medicine     nslog("med: %@" , med.name)     cell.textlabel?.text = med.name     cell.detailtextlabel?.text = "next due: " + med.nextduedate()     return cell } 

the result nslogs in cellforrowatindex path results in
