title: OCUnit in XCode 4, problems accessing class to test
body: <p>I added a Cocoa Touch testing bundle to my existing iPhone application, the default test seems to run (fail!) just fine, but when I try to add my class from my project to the test target I am not able access the class from that file.</p>
  
  <p>I added the file that I want to test to the unit testing target, but if I try and make an instance of the class I want to test, it is unknown. </p>
  
  <p>Any idea what I could be missing?</p>
