Exception 'Failed to get default FIRDatabase instance.....'

[banerjed]

Got this exception on the simulator window while launching - not sure why:

Exception 'Failed to get default FIRDatabase instance. Must call FIRApp.configure() before using FIRDatabase.' was thrown while invoking on target FirestackDatabase with params (

"/chat-messages/database-demo",
("orderByChild:createdAt",
"limitToLast:10",
"endAt:temp-id-484903"),
"child_added",
17
)
