title: Failed unit tests always show succeed notification when tested on device in XCode 6 beta swift
body: <p>Unit tests always show 'succeed' desktop notification when run on device in XCode 6 beta 6 in Swift.</p>
  
  <p>How to recreate:</p>
  
  <ul>
  <li>Create new iOS single-view app project with Swift.</li>
  <li>Go to the existing test and change it to <code>XCTAssert(false)</code> to make it fail.</li>
  <li>Run the tests on the device - it shows "Test Succeeded" desktop notification.</li>
  <li>Run the test on the emulator - it shows "Test Failed" notification as it should.</li>
  </ul>
  
  <h2>Update</h2>
  
  <ul>
  <li>There are test error messages in the output window when testing on device. But the desktop notification says "Test Succeeded".</li>
  <li>When I test on device and set a breakpoint in the test method - it does stop there.</li>
  </ul>
