Question

所以我正在努力将我的geoSearch功能从GeoFire迁移到Algolia，因为过滤方面还有更多选择，还有许多其他事情可以使生活变得更加轻松。

我目前正在使用它来搜索距离用户位置最近的事件。就像文档所说的（https://www.algolia.com/doc/guides/managing-results/refine-results/geolocation/）一样，我添加了此属性

“ _ geoloc”：{ “ lat”：37.7909427， “ lng”：-122.4084994 }

使地理搜索成为可能。之后，我使用SwiftLocation来获取用户当前地理查询/搜索的经度和纬度。文档说这样做（https://www.algolia.com/doc/api-reference/api-parameters/aroundLatLng/）

let query = Query(query: "query")
query.aroundLatLng = LatLng(lat: 40.71, lng: -74.01)

index.search(query, completionHandler: { (res, error) in
  print(res)
})

我用这段代码完成了

static func fetchEventsFromAlgolia(completion: @escaping (String) -> Void) {

    let client = Client(appID: Algolia.appID, apiKey: Algolia.apiKey)
    let index = client.index(withName:indice.events)
    let query = Query(query: "query")

    LocationService.getUserLocation { (currentLocation) in

        guard let latitude = currentLocation?.coordinate.latitude else {
            completion("error finding latitude")
            return
        }

        guard let longitude = currentLocation?.coordinate.longitude else {
            completion("error finding longitude")
            return
        }

        query.aroundLatLng = LatLng(lat: latitude, lng:longitude )
        query.aroundRadius = .all
        index.search(query, completionHandler: { (res, err) in
            if err == nil {
                guard let res = res else {
                    completion("error with res unwrapping")
                    return
                }


                let data = res["hits"]! as! [NSDictionary]
                print("Result: \(data.count)")
                print(res.description)
                completion("success events should have been printed")
            }else {
                completion(err as! String)
            }
        })


    }

}

但是，当我将结果打印到终端时，我什么也没得到。好像查询成功，但结果却没有回来。

这是针对我的具体情况的事件条目之一，在阿尔及利亚如何显示

如果有人可以看到我出了错，请告诉我！！！
