Firebase iOS push notification not received - ios

Question

I've setup the project as shown in the documentation. When the app is in the foreground I get the messages to the method applicationReceivedRemoteMessage but when the app is in the background I don't receive the notification. I tried sending the notification from the Firebase console.
Initially I thought might a problem with the certificates etc. But when I try sending the message via http://pushtry.com it works just fine.
So the problem is the way I configured the app. I've copied the AppDelegate here. Can someone figure out why it's not working please.
Also can someone tell me how to specify that I need to send notification for my sandbox mode. There is no way to select production / sandbox mode in the notification console in Firebase.
