I'm just use the PhotoKit to delete photos, just like this:

[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
    [PHAssetChangeRequest deleteAssets: arrayOfPHAssets];
} completionHandler:^(BOOL success, NSError *error) {
    NSLog(@"Finished deleting asset. %@", (success ? @"Success." : error));
