title: dyld library error while using cocoapods to add testing library
body: <p>I'm trying to install a testing library for a project on top of SenTestingKit. 
  Prior to installing, the project builds fine and runs the test suite using SenTestingKit. 
  However, after using cocoapods to install another testing framework like Specta or Kiwi (which apparently depend on SenTestingKit), the project builds, but then immediately throws this error:</p>
  
  <pre><code>dyld: Library not loaded: @rpath/SenTestingKit.framework/Versions/A/SenTestingKit
    Referenced from: [...]
    Reason: image not found
  </code></pre>
  
  <p>I've tried about a dozen different suggestions from people with similar problems (changing the target build settings test host, changing the target framework search paths, etc, making sure pods are configured for the test target, etc.), all to no avail. Any suggestions?</p>
