An Objective-C library for storing and querying geographic locations in realtime using Firebase.
GeoFire is an open-source library for iOS that allows developers to store and query data based on geographic location using Firebase Realtime Database. It solves the problem of performing realtime geospatial queries by enabling apps to efficiently retrieve keys within a specified area and receive updates as locations change. The library acts as a lightweight add-on to Firebase, making it easy to integrate location-based features without modifying existing data structures.
iOS developers building location-aware applications, such as ride-sharing apps, local business finders, or social apps with proximity-based features, who need realtime geospatial querying capabilities.
Developers choose GeoFire for its seamless integration with Firebase, realtime updates, and efficient querying that only loads relevant location data. Its lightweight design and compatibility with existing Firebase setups make it a practical choice for adding geospatial functionality without architectural overhauls.

Seamlessly integrates with Firebase Realtime Database to provide live updates as locations change, enabling dynamic apps like ride-sharing or delivery services with event-driven key entered/exited events.
Selectively loads only data within queried geographic areas, ensuring app responsiveness even with large datasets, as emphasized in the README's focus on lightweight performance.
Stores data in a separate format and location within Firebase, allowing integration without modifying existing data structures or security rules, preserving current app architecture.
Fully compatible with Swift projects via CocoaPods with framework support, offering modern iOS development flexibility alongside Objective-C, as demonstrated in code examples.
Tightly coupled with Firebase Realtime Database, making migration to other databases or services like Firestore difficult and adding vendor dependency that may incur costs or limit control.
Only supports circular radius and basic regional queries, lacking advanced features such as polygon searches, distance matrices, or complex spatial operations that other geospatial libraries offer.
Requires Firebase project configuration, security rules with .indexOn optimizations, and careful handling of version upgrades, as noted in the README's migration guides for breaking changes.
