RealmGeoQueries: A Swift repository from olilavoie

RealmGeoQueries simplifies spatial queries with Realm Cocoa. In the absence of and official functions, this library provide the possibility to do proximity search. It's not necessary to include Geohash or other types of indexes in the model class as it only needs latitude and longitude properties.

How To Get Started

Installation with CocoaPods

Usage

First, import module;

import GeoQueries

Model must have a latitude and longitude keys, that have to be named "lat" and "lng" respectively. You can use another property names (use "latitudeKey" and "longitudeKey" parameters).

Search with MapView MKCoordinateRegion; ```swift let results = try! Realm() .findInRegion(YourModelClass.self, region: mapView.region) ```

Search around the center with radius in meters;

let results = try! Realm()
    .findNearby(YourModelClass.self, origin: mapView.centerCoordinate, radius: 500, sortAscending: nil)

Filter Realm results with radius in meters;

let results = try! Realm()
    .objects(YourModelClass.self)
    .filter("type", "restaurant")
    .filterGeoRadius(mapView.centerCoordinate, radius: 500, sortAscending: nil)
