SwiftyDropbox listfolder result for pathDisplay showing results in small caps

You're not doing anything wrong. Dropbox is case-insensitive, and attempts to be case-preserving, but sometimes you won't see the original expected case. You should use pathLower when performing operations, as that's the canonicalized version of the path. You should use pathDisplay for display purposes, where the case will be preserved to the extent possible. Even in pathDisplay though, the original casing isn't always available. There's a note about this in the API v2 documentation, under "Case insensitivity":

"Also, while Dropbox is case-insensitive, it makes efforts to be case-preserving. Metadata.name will contain the correct case. Metadata.path_display usually will contain the correct case, but sometimes only in the last path component. If your app needs the correct case for all components, it can get it from the Metadata.name or last path component of each relevant Metadata.path_display entry."

There's also some information in the documentation for Metadata.pathDisplay. Metadata.name will contain the case-preserved name, so the workaround would be to build the path up from each of those.

We understand this is non-ideal of course, and I'll forward this on to the team as feedback, but I can't make any promises as to if or when this might be improved in the future.
