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?

To do that, goto Project (not target)→Build settings → Swift Compiler → Custom flags → Other swift flags section and edit the different configuration flags. Add the flags using the syntax “ -D <flag_name>”. NOTE: if you are not seeing Other swift flags section, you will be in the basic build settings mode.
Feature flags allow you to slowly rollout a feature, rather than doing a risky big bang launch, and are extremely helpful when used in a continuous integration and continuous delivery environment. At Optimizely, we commonly use feature flags to reduce the risk of complicated deploys like rolling out new APIs.
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.
