in my iOS project I used AES.cpp which can be built successfully with Xcode 15. Recently I downloaded Xcode16 trying to adapt for iOS18 and encountered compile error when building this file.
the error is as below:

The related code is in instr.h, which is a included header in AES.cpp:

I also created a empty project and then added this file. The compiling still failed, so it is not related my other codes in project. Are there some guys knowing what the reason is?
