Actually, it seems that the NSWorkspace method behaves differently, (assuming I'm using it correctly):
[[NSWorkspace sharedWorkspace] filenameExtension:@"pdf" isValidForType:(NSString *)kUTTypeText]
returns YES
whereas the UTTypeConformsTo() solution returns NO.
So am I passing the wrong value for Type?
Cheers,
Martin
