import AVKit

func getVideos() -> PHFetchResult<PHAsset> {
        let fetchOptions = PHFetchOptions()
        fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate",ascending: false)]
        fetchOptions.predicate = NSPredicate(format: "mediaType = %d",PHAssetMediaType.video.rawValue)
        return PHAsset.fetchAssets(with: fetchOptions)
}

let imagesAndVideos = getVideos()

imagesAndVideos.enumerateObjects({ (object, count, stop) in
            PHImageManager.default().requestAVAsset(forVideo: object, options: nil, resultHandler: { (avasset, audiomix, info) in
                guard let avasset = avasset else {
                    fatalError("avassset nil")
                }
