Debugging Qt with LLDB on macOS

[martinvej]

Hi, I'm trying to debug Qt while using the provided macOS installer frameworks.
I am aware of an issue with DYLD_IMAGE_SUFFIX on macOS as described here: https://bugreports.qt.io/browse/QTCREATORBUG-15439 and https://bugreports.qt.io/browse/QTBUG-31724

In the JIRA issue above, I can only see a resolution for Qt Creator, but I'm wondering about how one should go about debugging the frameworks with the shell command.

Example:

lldb
>env DYLD_IMAGE_SUFFIX=_debug
>target create QtWidgets.framework
>warning: (x86_64) /Users/randomuser/Qt5.10.0/5.10.0/clang_64/lib/QtWidgets.framework/QtWidgets empty dSYM file detected, dSYM was created with an executable with no debug info.
>Current executable set to 'QtWidgets.framework' (x86_64).

Any help would be greatly appreciated, thanks!
