swift - Google analytics not working on iOS 10 -

i'm had implemented google analysis , run app on 1 of ios devices. however, real time reporting still showing everything 0. had setup google analysis below. appreciated if suggestion given.

appdelegate.swift didfinishlaunchingwithoptions method : -

    guard let gai = gai.sharedinstance() else {         assert(false, "google analytics not confiugured correctly.")     }     gai.tracker(withtrackingid: "ua-10317xxxx-1")     // optional: automatically report uncaught exceptions.     gai.trackuncaughtexceptions = true 

loginvc.swift viewwillappear method : -

override func viewwillappear(_ animated: bool) {     super.viewwillappear(animated)      setuptracker() } 

loginvc.swift setuptracker() method : -

private func setuptracker() {     let name = "login vc"     guard let tracker = gai.sharedinstance().defaulttracker else { return }     tracker.set(kgaiscreenname, value: name)      guard let builder = gaidictionarybuilder.createscreenview() else { return }     tracker.send(builder.build() [nsobject : anyobject]) } 

need set default tracker of gai in app delegate below.

gai.sharedinstance().defaulttracker = gai.tracker(withtrackingid: "<<trakcing key goes here>>") 

also understand happening in background can check logs setting gai logger level kgailoglevelverbose

real-time count , ga features not real time me. might need give time see hits in ga dashboard. typically 10-15 mins
