Firebase Swift 3.0 data read unwrapping issue

dbRef.observe(.value, with: { (snapshot: FIRDataSnapshot in
     for thingy in snapshot.children {
       let thingyFinal = thingy as? FIRDataSnapshot
         print(thingyFinal)
}})

My database structure is as follows:

->mung-37e2c: { "users": { "kimkardashian": "stuff", "donaldtrump": "stuff" }, goals: { "goal1" : "stuff", "goal2" : "stuff" } }

What I cannot wrap my head around is that the error is triggered by the first line of my code:

dbRef.observe(.value, with: { (snapshot: FIRDataSnapshot in

Since I am not force unwrapping here, why is the unwrapping error being triggered. Also, the database has not nil values.

Try changing your code to :-

FIRDatabase.database().reference().observe(.value, with: { (snapshot: FIRDataSnapshot) in
 for thingy in snapshot.children {
   let thingyFinal = thingy as? FIRDataSnapshot
     print(thingyFinal)
   }
})
