[shashankmeddo]

My app is crashing oftenly for users PFA crashatics logs.
I am using block based notifier and starting it on app launch

Method called on didfinishlaunching ----->>>>
func listenInternetConnection () {
self.reach = Reachability.forLocalWiFi();

self.reach!.reachableBlock = {
  (reach: Reachability?) -> Void in
  self.checkAndUploadPendingConsultations();
}

self.reach!.unreachableBlock = {
  (reach: Reachability?) -> Void in
  //print("UNREACHABLE!")
}


self.reach!.startNotifier()

}

Please find logs ------->>>>>>
