FIRQueryDocumentSnapshot
@interface FIRQueryDocumentSnapshot : FIRDocumentSnapshotA QueryDocumentSnapshot contains data read from a document in your Firestore database as
part of a query. The document is guaranteed to exist and its data can be extracted with the
data property or by using subscript syntax to access a specific field.
A QueryDocumentSnapshot offers the same API surface as a DocumentSnapshot. As
deleted documents are not returned from queries, its exists property will always be true and
data() will never return nil.
