[Swifty] File search pagination problem

I have a method that counts the number of files that match a query. I'm noticing a problem where the "start" parameter isn't respected. In other words, the following calls return the exact same result: https://gist.github.com/jamesfzhang/8f5ce1bbd79161377eef

The documentation says the start parameter means "the starting index within the search results (used for paging)." So you'd expect to see different results when changing the start parameter. Can anyone else reproduce this?

EDIT: I solved the problem, it was my mistake. The offset counter I was keeping track of wasn't updating properly in the response callback.
