LLDB sometimes is not able to lookup/find symbols in a debug session

As the image bellow shows

Sometimes lldb is not able to help with some symbol. As far as I remember, this always happened but is very random and is normally some list back(), front(), size() method. This seems like an lldb issue because of how it works and not actually a swift project, but recently I hit those times enough to have a curiosity to ask if anyone saw this before and if there is a workaround to avoid that? Does anyone recommend give it a try to gdb?

Thanks in advance :)
