Hey everyone, we received the following reply from Apple, which solved our issue: Based on the error you see, we think that your “C Language Dialect” build setting is set to less than C11. Please update it to GNU11 or higher and try again. In our Build Setting, we changed the following entries: C Language Dialect to GNU17 C++ Language Dialect to GNU++23 CLANG_CXX_LANGUAGE_STANDARD to GNU++23 Note that not all these changes might be needed in your project. Hope this helps! Best Marc
