Clang code model doesn't work in qtcreator 4.11 under macOS

    After upgrading my qtcreator from 4.10 to 4.11 under macOS catalina, Clang Code Model doesn't work anymore. I have set Clang Code Model's Diagnosic Configuration to 'Checks for questionable constructs [built-in]' but there is not any diagnosic information in the editor.

    With qtcreator 4.11, Clang Code Model works will under Windows and Linux.
