Xcode Other Swift Flags not recognized in code

Question

I have a Swift project, I added a unit test target to it. my config file Constants.swift contains a struct:

struct Constants {
  struct Network {
    #if APITESTS
    static let serverURL = "https://www.servertest.com"
    #else
    static let serverURL = "https://www.server.com"
    #endif
  }
}

In my test target Other Swift Flags I added -DAPITESTS Then run the unit test with CMD+U In a log present in my test, I can see that it's "https://www.server.com" that is selected here when it should be servertest.

If I use #if DEBUG instead of APITESTS, it works. If I try to add APITESTS within Active Compilation Conditions (just like DEBUG) it is still not recognized.

Any clear explaination?

When you define a condition in the test target, it only affects the test; the main app is built based on its usual configuration. The two easy solutions I see here are to set an environment variable or define a special test configuration in the main app and set the scheme to use that configuration for tests.
