After changing macOS `PRODUCT_NAME` in AppInfo.xcconfig the app will not build until the build folder is cleaned

[jmagman]

BUNDLE_NAME is set to PRODUCT_NAME which gets used by Xcode to name the bridging header. And if you've already built with the old name, you get an error like:

Xcode/DerivedData/Runner-ctretxpfaeypegasfqwbmrjkizyw/Build/Intermediates.noindex/Runner.build/Debug/Runner.build/Objects-normal/x86_64/This_Gallery-Swift.h: No such file or directory

Where the name I set is This_Gallery.

I cleaned Product > Clean Build Folder which deleted the header generated by Xcode, then built again so it generated the new one. Then it ran with the new name:

There might be a real fix, but maybe the clean at least should be called out in the docs?

The triaged-desktop label is irrelevant if there is no team-desktop label or fyi-desktop label.
