Thanks to everyone for your comments and suggestions. I now have my app with embedded frameworks working as multiple individual projects or combined into a single workspace. It all works in Xcode 9 or 11 and archiving also works. The app was successfully notarized by Apple.
There is actually an informative technical note on the subject. https://developer.apple.com/library/archive/technotes/tn2435/_index.html I appreciate the list responding to an Xcode question. The xcode-users list has been shut down and I have yet to acquire a taste for the new apple-dev groups. Thanks again. --Richard Charles _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
