Interestingly, I believe that the question part of another question posted recently essentially answers yours. If you use:

-[NSFileManager contentsOfDirectoryAtURL:includingPropertiesForKeys:options:error:] 

(doc link), you can pass an option, NSDirectoryEnumerationSkipsHiddenFiles, to ignore hidden files so that you don't have to check for specific ones:

NSURL * selectedFolderURL = [NSURL fileURLWithPath:[selectedFolder stringValue]];
[myFileManager contentsOfDirectoryAtURL:selectedFolderURL
             includingPropertiesForKeys:[NSArray arrayWithObject:NSURLNameKey]
                                options:NSDirectoryEnumerationSkipsHiddenFiles
                                  error:&error];

Note that this returns absolute URLs, whereas the method in your question returns paths that are relative to the original directory. Easily worked around, but important to know especially if you're deleting stuff.
