currently... When I try to save my doc based app file I get an error dialog that says:
The document “Untitled” could not be saved as “test.CNDoc”.
that's it. that's everything. That's the whole error message.
this. used. to. work.
I've tried adding a UTI to my document type. That lead to a series of actual error messages that have nothing to do with me, the error complains about a deprecated code (that I'm not calling), being potentially caused by a missing UTI definition (it's not missing) and there's no indication at all that there's even documentation about how to do this.
.
It's like the entire NSCoding system has been turned off and they don't want you to know why so they just strung a bunch of made up words together that are completely unrelated.
