QueryPredicate

public enum QueryPredicate

Query predicates that can be used to filter results fetched by FirestoreQuery.

Construct predicates using one of the following ways:

let onlyFavourites: QueryPredicate = .whereField("isFavourite", isEqualTo: true)
let onlyFavourites2: QueryPredicate = .isEqualTo("isFavourite", true)
let onlyFavourites3: QueryPredicate = .where("isFavourite", isEqualTo: true)
