ios - Undefined symbols for architecture arm64, Xcode 12.3

Question

I have errors when trying to run tests. I read that the error may be related to unrelated files, but I did not find this problem in my project.

Has anyone encountered a similar problem and how did you solve it?

Undefined symbols for architecture arm64:
  "protocol descriptor for InTravel.URLRequestFactory", referenced from:
      l_got.$s8InTravel17URLRequestFactoryMp in Tests_RequestFactory.o
  "(extension in InTravel):InTravel.EndPointType.url.getter : Foundation.URL", referenced from:
      Tests_iOS.MockRequestFactory.createRequest(InTravel.EndPointType) throws -> Foundation.URLRequest in Tests_RequestFactory.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Check the target membership for your various files. Make sure that the file in which those symbols are defined is included in the target you're trying to build.
