title: Xcode/iOS xctest - Build input file cannot be found
body: <p>I created the first unit test target in our <code>iOS</code> application by simply clicking through the plus icon inside the test tab on the left navigator.
  (The target to be tested is set to the main application)</p>

  <p>The unit test target created itself successfully but when I try to run the pre-generated tests, it outputs an error message. The error message displays that the build input file cannot be found. More specifically, the file <code>/Plugins/XXXTests.xctest/XXXTests</code> cannot be found. I double checked and in fact that file is not in that directory. </p>

  <p>While I could not find anything similar to this problem, I tried everything that was close to it but nothing seemed to fix problem. </p>
  
  <p>Any help would be greatly appreciated!</p>
