[webkit-dev] Having trouble building

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
error: use of undeclared identifier '_subviews'; did you mean 'subviews'?
    _subviews = subviews;
note: 'subviews' declared here
- (void)_setSubviewsIvar:(NSMutableArray<__kindof NSView *> *)subviews {
error: explicitly assigning value of variable of type
'NSMutableArray<__kindof NSView *> *' to itself [-Werror,-Wself-assign]
    _subviews = subviews;
    ~~~~~~~~~ ^ ~~~~~~~~
error: use of undeclared identifier '_subviews'
    return (NSMutableArray *)_subviews;
3 errors generated.

Has anyone else run into this?
