I'm developing an app that has a Tableview that fetches profiles from firebase based on the the profiles' location. The location data of the profiles are queried through geofire. When the app view loads, the tableview just doesn't get filled. I've flagged the code at multiple points but just can't figure out the reason. I know the question is hard to answer without seeing my actual code, but what are some common reasons with a table won't get filled with data from firebase?
