" Linker command failed with exit code 1 " in unit test?

I setup the project by Xcode 8.2.1. I upgrade to Xcode 8.3.2. I can run the project and no error. But when I run the unit test to test my app , I got this problem:

enter image description here

I have tried some ways to solve it. For example: clean the Test host

Or remove the derivedData and clean the app. All of them weren't work for me. I don't known the reason why I got this error. Does anyone can help me? Thanks

That happened to me too a couple of times after removing a pod.

I just clean the project (Product --> Clean (Build Folder)) and when rebuilding, the error message is gone.

If you are here because it seems that you can't see more details about this error, right click and select 'Reveal in Log'.

I just ran into the most unhelpful error ever while adding unit tests to an Xcode project.

The issue was that the Podfile was not updated to include a test target. I fixed it with the following steps:

First, get the name of your test target.

Next, update your Podfile with this:

  target '<YOUR_PROJECT>Tests' do
      inherit! :search_paths

      # Any pods that may be needed for testing
  end

Then, run pod install.

After that, I was able to build & run tests.

Your mileage may vary...

The Host Application on my Test Target was set to None for me the error was resolved when I set that to my Project Target

You can set that in this dropdown in the General tab on your project Target:
