4.26 BigSur xCode errors

Hello! I create blank c++ project for editing in XCode. I create new c++ pawn file. I generate project files for xCode. I wait a long time for indexing project and i have errors:

What can i do to resolve this errors? It’s not code errors, it’s xCode problem, but i do not understand why.
xcode Version 12.3 (12C33)

Thank you.

have exactly the same issue changed to Xcode 11 but on compiling it tries to compile the metadata (?)(._myScript)
os Big Sur 11.1
MacBook pro-2018

The reason for that issue is that macro definitions are missing.
