        let fetchOptions = PHFetchOptions()

        let collection:PHFetchResult = PHAssetCollection.fetchAssetCollections(with: .album,subtype: .any,options: .some(fetchOptions))

          if let first_Obj:AnyObject = collection.firstObject{
              //found the album

//MARK:- Select Video
    }
    override func viewWillAppear(_ animated: Bool) {
        // Get size of the collectionView cell for thumbnail image
        if let layout = self.cameraRollCollectionView!.collectionViewLayout as? UICollectionViewFlowLayout{
            let cellSize = layout.itemSize

            self.assetThumbnailSize = CGSize(width: cellSize.width,height: cellSize.height)
        }

        //fetch the photos from collection
        self.photosAsset = (PHAsset.fetchAssets(in: self.assetCollection,options: nil) as AnyObject?) as! PHFetchResult<AnyObject>?   //HEAR I AM GETTING THE FATEL ERROR
