Thank you. That's what I was hoping you'd say. Cheers

Thank you. I get it. I implemented a call to .fileExporter in the MacCatalyst case and it is an acceptable solution — only one extra mouse click. However, I would like to point out that I'm not "littering the Documents folder with random things by default". In this case, the user chooses a "Save to File" option, which causes a carefully curated folder of information to be zipped and placed in their Documents folder for the purpose of being accessible for sharing with others - for example, so they can place it in Google Docs or Dropbox. (I also implement a "Send as an email attachment" option...) ...just sayin'
