Comment (by george.colpitts):

 Isn't it more accurate to say that the problem occurs with Xcode 5 rather
 than with 10.9? Given that Xcode 5 is out and installs on 10.8 the problem
 is not limited to 10.9, correct? If so the code that conditionalizes the
 fix on Mac OS 10.9 should be changed to conditionalize on Xcode 5 if that
 is possible, correct?
