ios - Topic Won't Save in Firebase

Question

I'm trying to let a user subscribe to a Topic and save it in Firebase. I've followed the guides from firebase.google.com and have added the following code when a user taps a button:

[[FIRMessaging messaging] subscribeToTopic:@"/topics/sampletopic"];

Nothing happens though when I test clicking this button. I've added what is necessary to the podfile. What am I missing?

edit: where does this even show up in Firebase? Where can I see my saved topics?
