No, you would need to pass dwarf-with-dsym as the debug format to the linker
to get external dsym files (I don't know if Qt's configure passes that on,
or if it only supports the options it recognises) or run dsymutil over the
binaries.

If you just ask for dwarf, the symbol information is kept in the executable
rather than a separate .dSYM file.


However, with the above build options we can step into Qt source just by
enabling the "Use [debug] suffix when loading frameworks" option in Xcode.

If you open the Info window for the application executable in Xcode then
this option is in the General tab.
