Question Xcode - Undefined symbol:

I have been trying to build this project for 3 days straight and it is killing me. the project works with AR Core extensions 1.31.0 but once I upgrade the project to AR Core extensions 1.37.0 which is required to utilize the geospatial creator I am unable to compile the project and I get the below errors. I have started a fresh project and installed and compiled with AR Core extensions 1.37.0 and I have gotten geospatial anchoring to work in this fresh project, but I cant seem to resolve this in the existing project. The project builds in unity but once I try to build in Xcode I get the errors towards the end of the build process. I have tried different versions of Xcode, reinstalling cocoa pods and the external dependency resolver, and just about anything else I can think of.

Delete the Editor folder in ExtensionsAssets. It creates version-specific files at build time, so whenever upgrading ARCore Extensions, some of these files need to be recreated.

 

I'm having the same problem, any solution please?
