ios - didReceiveRemoteNotification not called Swift -

for reason didreceiveremotenotification never called. have done following:

checklist of apns:

create appid allowed push notification

create ssl certificate valid certificate , app id

create provisioning profile same certificate , make sure add device

with code:

register app push notification

handle didregisterforremotenotificationswithdevicetoken method

set targets> capability> background modes> remote notification handle didreceiveremotenotification

yet function not seem called. code looks this:

  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     // override point customization after application launch.      if (application.respondstoselector("isregisteredforremotenotifications"))     {         // ios 8 notifications         application.registerusernotificationsettings(uiusernotificationsettings(fortypes: (.badge | .sound | .alert), categories: nil));         application.registerforremotenotifications()     }     else     {         // ios < 8 notifications         application.registerforremotenotificationtypes(.badge | .sound | .alert)     }       return true }   func application(application: uiapplication, didregisterforremotenotificationswithdevicetoken devicetoken: nsdata) {     let tokenchars = unsafepointer<cchar>(devicetoken.bytes)     var tokenstring = ""      var = 0; < devicetoken.length; i++ {         tokenstring += string(format: "%02.2hhx", arguments: [tokenchars[i]])     }      apnsid = tokenstring     println("******apnsid \(apnsid)")     dtoken = devicetoken     println("******dtoken \(dtoken)")     nsuserdefaults.standarduserdefaults().setobject(devicetoken, forkey: "devicetoken") }  func application(application: uiapplication, didfailtoregisterforremotenotificationswitherror error: nserror) {     println("***********didfailtoregisterforremotenotificationswitherror")     println(error) }  func application(application: uiapplication, didreceiveremotenotification userinfo: [nsobject : anyobject], fetchcompletionhandler completionhandler: (uibackgroundfetchresult) -> void) {      println("getting notification")      var message: nsstring = ""     var alert: anyobject? = userinfo["aps"]      println(userinfo["aps"])      if((alert) != nil){         var alert = uialertview()         alert.title = "title"         alert.message = "message"         alert.addbuttonwithtitle("ok")         alert.show()     }  }
