This might have broken the iOS Simulator build: Undefined symbols for architecture x86_64: "WebCore::operator<<(WTF::TextStream&, WebCore::Node const&)", referenced from: WTF::TextStream& WTF::operator<<<WebCore::Node>(WTF::TextStream&, WTF::RefPtr<WebCore::Node, WTF::RawPtrTraits<WebCore::Node>, WTF::DefaultRefDerefTraits<WebCore::Node> > const&) in UnifiedSource62-mm.o ld: symbol(s) not found for architecture x86_64
