Why is the line number 0 for my source code in symbolicated crash log?At line 4 in Thread 0, the line number is 0 for (MyCodeModule.swift:0). Why is that? Is there a way to get more details about where it crashed?This is from a crash log a customer sent. The crash seems to be coming from somewhere in string processing routines.Are Swift line number references only delivered for functions/methods in Swift classes, but not free-standing functions?Also, is there a way to get symbolicated names for the libswiftCore.dylib lines in the crashed thread?Thread 0 name: Dispatch queue: com.apple.main-thread

Xcode 12 crashes upon opening Developer Documentation in Window menu on macOS Catalina 10.15.6. Can't view documentation at all in Xcode. Is there a workaround to get this to work? This is a fresh install of Xcode 12 from the App Store.
Bug: Xcode 13.3 Symbol navigator lists duplicate classes in the left column after I restructured the hierarchy. I changed the superclass of a number of classes in my Objective-C project and the changed classes now appear inside the old superclass and the new superclass in the Hierarchical view.
Is there a workaround or fix for this?
I tried Clean Build Folder, quitting and relaunching Xcode, but these actions do not solve the problem.
