According to this link, I need to set Bundle Loader with below content in unittest target Build Settings



$(BUILT_PRODUCTS_DIR)/MyExistingApp.app/MyExistingApp

At least as of Xcode 7.3 test targets let you select a "Host Application". In the Test target (but not presently the UI Test target) this automatically populates the "Test Host" build setting, but not the "Bundle Loader", which can lead to classes not being found.



Considering this, if you set your test targets' "Bundle Loader" Build Setting to $(TEST_HOST), it will always contain the right value even if you change the Host Application.



This is effectively the opposite of the advice given in the link @yuwen-yan posted, and should amount to less work.

    I found $(TEST_HOST) to be the default configuration, however still one of my pods isn't found.

    In Xcode9.2, its now under Test target > Build settings > Testing > Test host. Adding $(TEST_HOST) still works. However, I also did update my cocoapods.

Experienced the same issue.
What fixed it for me was setting enable modules (c and objective-c) to YES in the Testing target Build Settings.

    So here is what worked for me...



    override func setUp() {

    super.setUp()

    let promise = expectation(description: "App has finished running")

    DispatchQueue.global(qos: .background).async{
    // Wait on the background thread
    sleep(4)
    DispatchQueue.main.async {
    // Fullfill the promise in the main thread
    promise.fulfill()
    }
    }

    // Initialize the storyboard
    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    // Get the view controller
    sut = storyboard.instantiateViewController(withIdentifier: String(describing: ViewController.self)) as? ViewController
    _ = sut.view

    waitForExpectations(timeout: 5) { (_) in
    // Finish set up after the app is done running its code
    }

    }// End setUp() Method

      Experienced the same linker error after adding test target to old project which was created 2 or 3 XCode versions ago. Furthermore, project has various xcodeproject/target/bundle names. All possible renames, cleanings, Build settings, Build phases, Scheme manipulations did not worked for me.



      What did actually worked after a long struggle is recreating the project along with all targets from scratch in latest Xcode version. It finally links! And in this case you don't even need to manually modify Search paths, Bundle loader, Xcode will do it for you.

        This error may be the result of having wrong test target type, namely ui test target.



        UI test targets can't use the internals of the main target, not even with @testable imports. Unit test targets OTOH can use the internals.



        See more details in this answer.



        (I believe this has changed in some XCode version which causes confusion. Typical way is just to include a huge bunch of files from the original target in the ui test target. A proper way is to design UI tests in such a way that they don't need or use much code from the main target.)

          Below are the steps that I performed to fix the issue while trying to add unit test target in Xcode 9:




          1. Go to 'Manage Schemes'.

          2. Click on '+' button at the bottom.

          3. Select the newly added Target and select 'OK'.

          4. Make sure 'Shared' option is selected for the newly added target.

            At least as of Xcode 7.3 test targets let you select a "Host Application". In the Test target (but not presently the UI Test target) this automatically populates the "Test Host" build setting, but not the "Bundle Loader", which can lead to classes not being found.



            Considering this, if you set your test targets' "Bundle Loader" Build Setting to $(TEST_HOST), it will always contain the right value even if you change the Host Application.



            This is effectively the opposite of the advice given in the link @yuwen-yan posted, and should amount to less work.

              I found $(TEST_HOST) to be the default configuration, however still one of my pods isn't found.

              In Xcode9.2, its now under Test target > Build settings > Testing > Test host. Adding $(TEST_HOST) still works. However, I also did update my cocoapods.

            Experienced the same issue.
            What fixed it for me was setting enable modules (c and objective-c) to YES in the Testing target Build Settings.

                            Experienced the same linker error after adding test target to old project which was created 2 or 3 XCode versions ago. Furthermore, project has various xcodeproject/target/bundle names. All possible renames, cleanings, Build settings, Build phases, Scheme manipulations did not worked for me.



                            What did actually worked after a long struggle is recreating the project along with all targets from scratch in latest Xcode version. It finally links! And in this case you don't even need to manually modify Search paths, Bundle loader, Xcode will do it for you.

                                    This error may be the result of having wrong test target type, namely ui test target.



                                    UI test targets can't use the internals of the main target, not even with @testable imports. Unit test targets OTOH can use the internals.



                                    See more details in this answer.



                                    (I believe this has changed in some XCode version which causes confusion. Typical way is just to include a huge bunch of files from the original target in the ui test target. A proper way is to design UI tests in such a way that they don't need or use much code from the main target.)

                                        UI test targets can't use the internals of the main target, not even with @testable imports. Unit test targets OTOH can use the internals.



                                        See more details in this answer.



                                        (I believe this has changed in some XCode version which causes confusion. Typical way is just to include a huge bunch of files from the original target in the ui test target. A proper way is to design UI tests in such a way that they don't need or use much code from the main target.)

                                        This error may be the result of having wrong test target type, namely ui test target.

                                            Below are the steps that I performed to fix the issue while trying to add unit test target in Xcode 9:




                                            1. Go to 'Manage Schemes'.

                                            2. Click on '+' button at the bottom.

                                            3. Select the newly added Target and select 'OK'.

                                            4. Make sure 'Shared' option is selected for the newly added target.
