Xcode 16 breaks fundamental feature of error/warning clickthrough to a given header or .cpp file. The issues list will jump to the point of include, instead of the actual error/warning. There's not even a highlighted line since these files aren't the source of the error.
Not really sure how this one got through QA since Apple uses Xcode internally. Now I'm constantly having to scour the report navigator, open the items, and then manually jump to file/line.
