This usually indicates that project itself failed to compile. Please check the xcodebuild log for more details: /var/folders/ys/5mpd508n7cn480b721dsq99m0000gn/T/carthage-xcodebuild.XnxTXQ.log`

Same for me, but the log says BUILD SUCCESSFUL.

If you've already switched to Xcode12, this will still work without adding a version.

@funzin well done

Thank you @funzin for the great update to the script.

where to include this script when trying to solve this issue?
