swift - Push notification not receiving in background iOS

Question

I am doing push notification in my project through GCM. My Application is able to receive notification in foreground but not in background.

I receive a message inside the method

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])  

when the application is in foreground but I am not getting any call to the method

func application( application: UIApplication,
    didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
    fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void)

when the application in background mode.

I had a long search in Internet and came to know that it's the problem with the payload format I receive. The payload I received looks like

[notification: {"body":"anything","title":"any title"}, priority: high, content_available: true, to: kcF23gblKok...., collapse_key: do_not_collapse, from: 7812....]

Can anyone suggest me the correct format of payload?
