body: <p>I have added PLCrashReporter using POD</p>
  
  <pre><code>use_frameworks! 
  pod 'PLCrashReporter'
  </code></pre>
  
  <p>I have imported following files in Briding Header to use in my swift project</p>
  
  <pre><code>#import &lt;CrashReporter/CrashReporter.h&gt;
  #import &lt;CrashReporter/PLCrashReport.h&gt;
  </code></pre>
  
  <p>If I run the project, then I don't get any problem and it works as expected</p>
  
  <p>If I do xcode unit-test I get the following error
