ios - Background Location Update Not Working -

i trying implement background fetch location, works perfect inside of ios simulator, when build on phone, not appear work. here current code:

import uikit import corelocation  class currentconditonsviewcontroller: uiviewcontroller, cllocationmanagerdelegate {  lazy var locationmanager: cllocationmanager! = {     let manager = cllocationmanager()     manager.desiredaccuracy = kcllocationaccuracyhundredmeters     manager.delegate = self     manager.requestalwaysauthorization()     manager.distancefilter = 2000     if #available(ios 9.0, *) {         manager.allowsbackgroundlocationupdates = true     } else {         // fallback on earlier versions     };     return manager }()     var seenerror : bool = false var locationfixachieved : bool = false var locationstatus : nsstring = "not started" var userlocation : string! var userlatitude : double! var userlongitude : double! var usertemperaturecelsius : bool!   override func viewdidload() {     locationmanager.startupdatinglocation();      refresh()  }  func refresh(){     initlocationmanager() }  func initlocationmanager() {     seenerror = false     locationfixachieved = false     locationmanager = cllocationmanager()     locationmanager.delegate = self     locationmanager.desiredaccuracy = kcllocationaccuracynearesttenmeters     locationmanager.requestalwaysauthorization()     locationmanager.startupdatinglocation() }  func displaylocationinfo(placemark: clplacemark?) {     if let containsplacemark = placemark {         //stop updating location save battery life         locationmanager.stopupdatinglocation()         let locality = (containsplacemark.locality != nil) ? containsplacemark.locality : ""         let administrativearea = (containsplacemark.administrativearea != nil) ? containsplacemark.administrativearea : ""         //println(locality)         //println(postalcode)         //println(administrativearea)         //println(country)      } }  // mark: - cllocationmanagerdelegate  func locationmanager(manager: cllocationmanager, didupdatetolocation newlocation: cllocation, fromlocation oldlocation: cllocation) {     // add annotation map.    let coords =  newlocation.coordinate     userlatitude = coords.latitude     userlongitude = coords.longitude      if uiapplication.sharedapplication().applicationstate == .active {         nslog("app in foreground. new location %@", newlocation)         clgeocoder().reversegeocodelocation(newlocation, completionhandler: {(placemarks, error) -> void in             if error != nil {                 print("reverse geocoder failed error" + error!.localizeddescription)                 return             }              if placemarks!.count > 0 {                 let pm = placemarks![0]                 self.displaylocationinfo(pm);              } else {                 print("problem data received geocoder")             }           })       } else {         nslog("app backgrounded. new location %@", newlocation)         let coord = newlocation.coordinate         let lat = coord.latitude.description;         let lng = coord.longitude.description;         let localnotification:uilocalnotification = uilocalnotification()         localnotification.alertaction = "project rainman"         localnotification.alertbody = "location updated: " + lat + ", " + lng         localnotification.firedate = nsdate(timeintervalsincenow: 8)         uiapplication.sharedapplication().schedulelocalnotification(localnotification)      } }  func locationmanager(manager: cllocationmanager,                      didchangeauthorizationstatus status: clauthorizationstatus) {     var shouldiallow = false     var locationstatus = ""     switch status {     case clauthorizationstatus.restricted:         locationstatus = "restricted access location"     case clauthorizationstatus.denied:         locationstatus = "user denied access location"     case clauthorizationstatus.notdetermined:         locationstatus = "status not determined"     default:         locationstatus = "allowed location access"         shouldiallow = true     }     nsnotificationcenter.defaultcenter().postnotificationname("labelhasbeenupdated", object: nil)     if (shouldiallow == true) {         nslog("location allowed")         // start location services         if #available(ios 9.0, *) {             locationmanager.allowsbackgroundlocationupdates = true         } else {             // fallback on earlier versions         };         locationmanager.startupdatinglocation()     } else {         nslog("denied access: \(locationstatus)")     } } } // end of class 

i not receive notification on actual device, , worth noting morning code updates app when app running. have spent couple days on code , sure it's simple, appreciated!
