objc API: filesRoutes listFolder method not returning files

I see you're calling listFolder, but aren't calling listFolderContinue. You aren't always guaranteed to get all entries returned by calling just listFolder. You need to check the result, and if DBFILESListFolderResult.hasMore is true, call back to listFolderContinue to get more results (and the same for the listFolderContinue result). You can find more information in the listFolder documentation.

The requirement to check hasMore and use listFolderContinue as directed has always been part of API v2. Whether or not hasMore actually comes back as true in practice however depends on a variety of factors that can change over time, per account, and per path. Due to some backend updates, how often this does happen may be increased right now, but we're working on improving that. In any case though, you'll still need to have listFolderContinue implemented to guarantee that you get all of the results.
