The same error exists in Xcode 14.3 Beta 3

Finally I found my issue! It was not on signing issues at all. In release builds I generally set GCC_SYMBOLS_PRIVATE_EXTERN = NO But I forgot to flag all the exported functions with __attribute__((visibility("default")))

This is the SampleCode https://developer.apple.com/documentation/coreaudio/creating_an_audio_server_driver_plug-in which I used to start our project
