ios - programmatic UITableView's didSelectRowAtIndexPath not responding to touch -

i programmatically created uitableview custom keyboard extension within default keyboardviewcontroller.swift reason didselectrowatindexpath not responding @ all. i've made sure set userinteractionenabled true both table cells , made sure set allowsselectionduringediting true. tableview being populated , cells highlighted when touch them logs not appearing @ (nor method breaking when there breakpoint on it).

anyone have ideas on may have screwed make happen?

class keyboardviewcontroller: uiinputviewcontroller, uitableviewdelegate, uitableviewdata source {   var tableview: uitableview = uitableview()  //other setup  override func viewdidload() {   super.viewdidload    // other setup here    tableview.frame = cgrectmake(0, 0, 320, 160)   tableview.delegate = self   tableview.datasource = self   tableview.registerclass(uitableviewcell.self, forcellreuseidentifier: "cell")   tableview.allowsselection = true   tableview.allowsselectionduringediting = true   tableview.userinteractionenabled = true   self.view.addsubview(tableview)  }  //delegate&datasource methods func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     let sectiontitle = artistsectiontitles[section]     let sectionartist = artists[sectiontitle]      return sectionartist!.count }  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {      var cell:uitableviewcell = tableview.dequeuereusablecellwithidentifier("cell") uitableviewcell     cell.userinteractionenabled = true     let sectiontitle = artistsectiontitles[indexpath.section]     let sectionartists = artists[sectiontitle]     let artist = sectionartists?[indexpath.row] nsstring      cell.textlabel?.text = artist     return cell }  func tableview(tableview: uitableview, heightforrowatindexpath indexpath: nsindexpath) -> cgfloat {     return 22 }  func tableview(tableview: uitableview, didselectrowatindexpath indexpath: nsindexpath) {     tableview.deselectrowatindexpath(indexpath, animated: false)     println("you selected cell #\(indexpath.row)!") }  func tableview(tableview: uitableview, titleforheaderinsection section: int) -> string? {     return artistsectiontitles[section] }  func sectionindextitlesfortableview(tableview: uitableview) -> [anyobject]! {     return artistsectiontitles }  func numberofsectionsintableview(tableview: uitableview) -> int {     return artistsectiontitles.count } 

how tracking selection in fact not work? because if rows light - should work.

maybe changing tableview delegate somewhere?

also try changing cell selectionstyle property.
