Unable to see logs in App Extension console

I am running a Safari Web Extension and i am unable to see any logs printed from func beginRequest.
What could be the potential cause of this ?

I ran into this too, I think the debugger in Xcode will by default connect to the parent application. You need to select from the debug menu item, in Xcode, and then attach to process item. Your extension should be in the list, and selecting it should make it so the output from the app extension gets logged to the debugger.
