If I pass -DOBJC_OLD_DISPATCH_PROTOTYPES flag to the compiler, this error no longer occurs. However another error jumped out:

I tried to compile the latest official Chrome dev version 79.0.3938.0 and got the same error.

Chromium does not support building with 10.15 SDK.

But there are still bugs related to 10.14 SDK...

See crbug Chromium already supports building with Xcode 11 in master branch. I tried version 80+ and build succeeded. I didn't check changelogs so I don't know from which specific version number Xcode 11 is supported....

Cool, I guess we can close this once Chromium 80 comes out.

I successfully built chromium 80 on catalina using the tag 80.0.3987.87-2.1.

Closing because 80 is out.
