I’m following the instructions from https://firebase.google.com/docs/database/ios/read-and-write to read a record from Firebase Realtime Database:

    StorageWrapper.ref.child("users").child(id)
        .observeSingleEvent(of: .value, with:
        {
            snapshot in
            print("DEBUG:  snapshot value = (String(describing: snapshot.value))")

            if let value = snapshot.value as? NSDictionary
            {
                print("DEBUG:  value = (String(describing: value))")
                if let email = value["email"] as? String,
                   let fullname = value["fullname"] as? String
                {
                    user = User(id: id, fullname: fullname, email: email)
                    print("DEBUG:  snapshotted user (String(describing: user))")
                }
            }

The snapshot is valid and the first print statement returns:

DEBUG:  snapshot value = Optional(["email": [email protected],"fullname": Joe Tester])

The conversion to NSDictionary fails. I’ve also tried converting the snapshot value to [String: Any] and [String: String] with no luck.

Am I missing something simple?
