My project has 2 windows. In this configuration it is compiled and runs without problems. I'm trying to add another window using a new Code module. Even if this module is empty, as it was generated, or if I insert a new routine in it, at compilation I receive the following error message:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Error: ** BUILD FAILED **

The following build commands failed:
Ld /Users/traianmacaveiu/Desktop/B4iBuildServer/UploadedProjects/<user id>/Payload/Extrase\\ Trezo normal arm64
(1 failure)
(full error message in attached file)

I deleted the folder from Uploaded Projects, I used Clean Project, but the result is the same ...

After several attempts to change User_id and delete files from Uploaded Projects, the issue has been resolved.

Is it normal that when I change the compiler from Debug to Release or vice versa, I have to delete the files in the Uploaded Project related to User_id? Otherwise I get compile error.
