ios - Search through custom objects with UISearchController -

i'm trying create uisearchcontroller search through custom team objects , add , remove them in filteredarray. seem experience weird behaviour can't seem solve. tableview instance below:

and when instance search on "copen" returns:

why selected should not be?

my code:

override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("teamcell", forindexpath: indexpath) as! teamcell      if (self.teamsearchcontroller.active) {          let team = filteredtabledata[indexpath.row] as! team         cell.textlabel?.text = filteredtabledata[indexpath.row].name      } else {     let team = self.teamarray[indexpath.row] team     cell.textlabel?.font = uifont(name: "helveticaneue-light", size: 20)     cell.textlabel?.text = self.teamarray[indexpath.row].name string      }        var removed = false      (index, value) in enumerate(self.teamselected) {         if (value.id == team.id) {              cell.accessoryview = cell.accessorycheck             removed = true         }     }      if (!removed) {         cell.accessoryview = cell.accessoryuncheck      }      cell.selectionstyle = uitableviewcellselectionstyle.none       return cell } 

updatesearchcontroller

func updatesearchresultsforsearchcontroller(searchcontroller: uisearchcontroller) {      filteredtabledata.removeall(keepcapacity: false)      let searchpredicate = nspredicate(format: "name contains[c] %@ or shortname contains[c] %@", searchcontroller.searchbar.text, searchcontroller.searchbar.text)     let array = (teamarray nsarray).filteredarrayusingpredicate(searchpredicate) as! [team]     filteredtabledata = array      self.tableview.reloaddata() }

the team selected because let team = self.teamarray[indexpath.row] team indexpath.row == 0 returns cloud9 , not wolves. fix team filteredtabledata follow

override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell { let cell = tableview.dequeuereusablecellwithidentifier("teamcell", forindexpath: indexpath) as! teamcell  var team : team!  if (self.teamsearchcontroller.active) {     team = filteredtabledata[indexpath.row] as! team     cell.textlabel?.text = team.name  } else { team = self.teamarray[indexpath.row] team cell.textlabel?.font = uifont(name: "helveticaneue-light", size: 20) cell.textlabel?.text = team.name string  }  var removed = false  (index, value) in enumerate(self.teamselected) {     if (value.id == team.id) {          cell.accessoryview = cell.accessorycheck         removed = true     } }  if (!removed) {     cell.accessoryview = cell.accessoryuncheck  }  cell.selectionstyle = uitableviewcellselectionstyle.none   return cell }
