Unable to get assetFetchOptions options in Objective-C

[shanthaAithertech]

I'm not able to get the assetFetchOptions options in objective-c so unable to set the fetchOptions.predicate. I want to fetch only images form library but it is showing video.

PHFetchOptions *fetchOptions = [PHFetchOptions new];
fetchOptions.predicate = [NSPredicate predicateWithFormat:@"mediaType == %d", PHAssetMediaTypeImage];
