Swift 4.2

let allPhotosOptions = PHFetchOptions()
allPhotosOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
fetchResult = PHAsset.fetchAssets(with: allPhotosOptions)

You may utilize PHFetchOptions.

PHFetchOptions Class Reference>sortDescriptors

Try this:

        let options = PHFetchOptions()
        options.sortDescriptors = [NSSortDescriptor(key: "endDate", ascending: false)]
        let collection:PHFetchResult = PHAssetCollection.fetchAssetCollectionsWithType(.SmartAlbum, subtype: .SmartAlbumUserLibrary, options: options)
