It shows “Undefined symbol: _GetUA”, “Linker command failed with exit code 1 (use -v to see invocation)”. Any ideas?
This would imply that you are missing a support library for something, but that symbol means nothing in terms of stock Unity that I am aware of. What other libraries or packages are you trying to use?
Thank you very much. I’ve solved the problem. It was a third-party library imported by a package which should not placed in the project.
