xcode 12 used to have a feature that allowed you to right click a filepath that was included and "Go to definition" to open that file in the editor. This made it much easier to view locally written headers, and system headers. Any chance this can be added back in?
xcode 13 seems to have broken tags
Could you explain in detail how you did in Xcode 12 (I cannot find how to reach this Go to definition. With an example of url.
In any case, you can file a bug report.
