When I use the Xcode 13 beta to build an app, view-based NSTableViews don't draw anything when the app is run under macOS 10.12 or earlier. I filed a bug (FB9278241), just wondering if anyone has any insight or workaround.
Tables built by Xcode 13 beta don't work in macOS 10.12
It looks like this may be fixed, I couldn't replicate it with Xcode 13 beta 4.
