Do I have to tick the testing target in Xcode in order to reach the testing file in my main project

In order to avoid api calls while testing, I override the API classes in my testing bundle and returning a demi objects.

 var profileStore : ProfileStore
 if ProcessInfo.processInfo.arguments.contains("TESTING_ENV") {
        let testBundle = Bundle(for: type(of: self))
        let projectName = testBundle.infoDictionary!["CFBundleName"] as? String
        let className = "MemProfileStore"
        if let classType =  NSClassFromString("\(projectName!).\(className)")! as? ProfileStore.Type {
        profileStore = classType.init()
    } else {. //create the profileStore from the main bundle
        profileStore = ProfileStore()
    }

The file that the current code appears at us in both of the targets.

I have 2 questions: 1) Is there a way to reach "MemProfileStore" file without including it in the main bundle?

2) If I do include "MemProfileStore" in the mainBundle: will it be a part of my Release version? I realised that it is reachable from the mainBundle as well (when I run the app not in a testing environment)
