Getting Camera Roll with Photos.framework

PhotosCameraRoll.m

  PHFetchResult *result = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum
                                                                   subtype:PHAssetCollectionSubtypeSmartAlbumUserLibrary
                                                                   options:nil];
  PHAssetCollection *assetCollection = result.firstObject;
  NSLog(@"%@", assetCollection.localizedTitle);
  // Camera Roll

I'm getting a assetCollection == nil on iPad mini iOS 10.3.1

(lldb) po query
<PHUnauthorizedFetchResult: 0x170135c20> count=0

    private static func getCameraRollAlbum() -> PHAssetCollection?
    {
        // https://gist.github.com/Koze/f8b3adf542c5dae6e9cf
        //
        let query = PHAssetCollection.fetchAssetCollections(with: .smartAlbum,
                                                         subtype: .smartAlbumUserLibrary,
                                                         options: nil)
        let result: PHAssetCollection? = query.firstObject
        print("[nmessenger] [debug] camera roll name" + (result?.localizedTitle ?? ""))
        
        return result
    }

Hello Is there any way to get all albums ?

If iCloud is turned on, Camera Roll is not returned by this method. It instead returns All Photos. Is there any way to get Camera Roll asset collection when iCloud is turned on?

pretty late for @dodikk I guess but anyone else getting assetCollection == nil needs to add permissions in their info.plist
