This symbol from UIProcess/API/cpp/WKRetainPtr.h is not used by other projects. No headers contains this symbol. We should not export this symbol.
Created attachment 303088 [details] Proposed patch
The reason why this is needed is that this header is a private one, used by WebKit tools. But I don't think that there is any reason to have the symbol exported.
