PHAsset，如何获取地理位置周围的所有图像

Question

我想从照片库中获取地理位置（纬度/经度+距离）周围的所有图像。 目前，我正在使用以下代码。它可以工作，但这意味着我需要遍历所有PHAsset，是否有更好的解决方案？我发现没有有用的谓词可用于PHFetchOptions。

let photosFetchResult = PHAsset.fetchAssets(with: nil)
let poiLocation = CLLocation(latitude: geoLocation.coordinate.latitude, longitude: geoLocation.coordinate.longitude)

 // find all images located near the geolocation
 var filteredImages = [LocalImage]()
 for i in 0..<photosFetchResult.count {
      let currentObject = photosFetchResult.object(at: i) 
      if let imageLocation = currentObject.location {
          let distanceFromPoi = poiLocation.distance(from: imageLocation)
          if distanceFromPoi <= Cste.radiusSearchImage {
              filteredImages.append(LocalImage(image: getAssetThumbnail(asset:currentObject),
                                               asset: currentObject,
                                               distanceFrom: distanceFromPoi))
                      }
    }

谢谢
