[webkit-dev] Having trouble building

[Ken Russell]

Hi,

Recently I upgraded to Xcode 11.0 and re-synced to top-of-tree WebKit. With
a clean WebKitBuild directory I'm seeing the following build error:

$ ./Tools/Scripts/build-webkit --release > build-log.txt

...

In file included from
/Users/kbr/src/WebKit/WebKitBuild/Release/DerivedSources/WebKitLegacy/unified-sources/UnifiedSource20-mm.mm:4:

    return (NSMutableArray *)_subviews;
                             ^

Has anyone else run into this?

Thanks,
