Two obersvations
1) If you’re sure it’s not nil, which for that particular case of an enumerator from a filemanager I’d agree it’s not (can’t make one work in a playground to test) then just force-unwrap it
2) As concise as ‘for case let url as NSURL in eumerator’ is, I think the original code was somewhat clearer for the next guy maintaining it
