Preview

The attached video shows a demo ObjC debug session on Windows with Visual Studio Code and the CodeLLDB plugin.

Please note:

• In order to get the language setting right in PDBs, target binaries must be built with a patched Clang compiler (i.e. RuntimeTest.exe in the demo).
• The preview uses the attached liblldb.dll for debugging. Please find more info here on how to wire it up: https://weliveindetail.github.io/blog/post/2021/04/14/tot-lldb-vscode.html
