title: Receiving EXC_Breakpoint error before running code
body: <p>I'm working on some <code>Xcode Testing</code>. </p>
  
  <p>When I run one of our tests, I'm reciving a <code>EXC_Breakpoint</code> error message before the test has begun execution. It's difficult to debug with beakpoints as the error occure before running any code. </p>
  
  <p>I have a feeling it has someting to do with my Xcode setting but can't seem to find the answer.</p>
  
  <p>The last line that we recevie from the output is:</p>
  
  <pre><code>fatal error: unexpectedly found nil while unwrapping an Optional value
  (lldb)
  </code></pre>
