    "content-available" = 1;
}, AnyHashable("data"): {
    chore =     {
        desc = huu;
        name = yuuu;
        pk = 125;
        reward = "5.00";
        sched = "2018-04-12T09:52:13+08:00";
    };
    "notification_id" = 16;
    pusher =     {
        publishId = "pubid-01ff965a-20af-4a58-9901-89782043d832";
    };
}]

You are probably dealing with a dictionary of `[AnyHashable:Any]`, but in this case it seems your keys are `String` so you should be able to access the elements via `notif["alert"]` for example — Paulw11, Apr 12 '18 at 05:59
you can try, let strTitle = (userInfo["aps"] as! NSDictionary).value(forKey: "notification") as! NSDictionary let title = strTitle.value(forKeyPath: "alert.title") let body = strTitle.value(forKeyPath: "alert.body") — Abhirajsinh Thakore, Apr 12 '18 at 06:04
If i am not wrong you want to extract the received notification data right.? — Abhirajsinh Thakore, Apr 12 '18 at 06:07

You can Possibly Try:

Update for Swift 5+:

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    guard let arrAPS = userInfo["aps"] as? [String: Any] else { return }
    if application.applicationState == .active{
        guard let arrAlert = arrAPS["alert"] as? [String:Any] else { return }

        let strTitle:String = arrAlert["title"] as? String ?? ""
        let strBody:String = arrAlert["body"] as? String ?? ""

        let alert = UIAlertController(title: strTitle, message: strBody, preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "Ok", style: .default) { action in
            print("OK Action")
        })
        self.window?.rootViewController?.present(alert, animated: true)
    } else {
        guard let arrNotification = arrAPS["notification"] as? [String:Any] else { return }
        guard let arrAlert = arrNotification["alert"] as? [String:Any] else { return }

        let strTitle:String = arrAlert["title"] as? String ?? ""
        print("Title --", strTitle)
        let strBody:String = arrAlert["body"] as? String ?? ""
        print("Body --", strBody)
    }
}

Swift 2+ :

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {

    guard let dictAPS = userInfo["aps"] as? NSDictionary else { return }

    if application.applicationState == .active{
        let title = dictAPS.value(forKeyPath: "alert.title")
        let body = dictAPS.value(forKeyPath: "alert.body")
        let alert = UIAlertController(title: "\(title!)", message: "\(String(describing: body))", preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "Ok", style: .default) { action in
                   })
        self.window?.rootViewController?.present(alert, animated: true)
    }else{
        guard let dictNoti = dictAPS.value(forKey: "notification") as? NSDictionary else { return }
        let title = dictNoti.value(forKeyPath: "alert.title")
        print(title)
        let body = dictNoti.value(forKeyPath: "alert.body")
        print(body)
    }
}

You can try: let strData = (userInfo["data"] as! NSDictionary) let desc = strData.value(forKeyPath: "chore.desc") let name = strData.value(forKeyPath: "chore.name") let pk = strData.value(forKeyPath: "chore.pk") let reward = strData.value(forKeyPath: "chore.reward") let sched = strData.value(forKeyPath: "chore.sched") – Abhirajsinh Thakore Apr 12 '18 at 06:23
but i want to trigger it only when notification is tap – Apr 12 '18 at 06:24
This Method will be called On tap:, func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { //Your code to handle events } – Abhirajsinh Thakore Apr 12 '18 at 06:43
Invalid redeclaration of 'userNotificationCenter(_:didReceive: – Apr 12 '18 at 06:45
do the things inside that, I guess this is only called when tapped on notification. – Abhirajsinh Thakore Apr 12 '18 at 06:48

APS data can be checked as below. You can check each keys as below to avoid crashing app if particular key is not available in notification data and handle accordingly.

if (userInfo["aps"] as? [String:Any]) != nil {
   if let data = userInfo["data"] as? String{
      if let desc = userInfo["desc"] as? String {
          //Access variable desc here...
          print(desc)
      } 
   }
}

but how to trigger it only when user tap the notification – Apr 12 '18 at 06:26
Below method will be called when user taps on notification when App is in background or closed - application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) In case of App in foreground you can manage notification by UserNotificationCenter methods and delegates. – Apurv Soni Apr 12 '18 at 06:32
i only want to get and print the data when notifcation is tapped – Apr 12 '18 at 06:37
Okay. When app is in background or launched from Push notification you will get data in “didReceiveRemoteNotification” method and incase of application is running notification will not be displayed if you have not managed it using “UserNotificationCenter”. In later case you will get notification data in “userNotificationCenter didReceive response: UNNotificationResponse” method. Use above code to handle it – Apurv Soni Apr 12 '18 at 06:46
Actually Sir i can receieved notif in foreground or background , what i want is that hash data will only be printed or i want to only get the data when notification is tapped. – Apr 12 '18 at 06:55
