The NSDocumentController method:
- (__kindof NSDocument *)makeUntitledDocumentOfType:(NSString *)typeName error:(NSError * _Nullable *)outError;
is asking for a typeName. From discussions on the web it is not clear exactly what typeName is other than a NSString. Using jus tthe UTI isn't working for me. Various suggestions are to append "modules" of various sorts. I'm lost. Anyone have a clear answer? I've tried "My_App_Name.myUTI, but no luck.
Thanks
