[Clang][Sema] Fix attribute mismatch warning for ObjC class properties

Authored by egorzhdan on Dec 30 2021, 6:27 AM.



If a class declares an instance property, and an inheritor class declares a class property with the same name, Clang Sema currently treats the latter as an overridden property, and compares the attributes of the two properties to check for a mismatch. The resulting diagnostics might be misleading, since neither of the properties actually overrides the another one.

I think we would still want to diagnose any mismatches between class properties that override a class property in the superclass. do you think that would be useful? You can adjust the lookup to take that into account.
