title: Can't run iPhone simulator - file "Logs" couldn't be saved
body: <p>iPhone simulator doesn't work. Displays error message:</p>
  
  <blockquote>
    <p>The file “Logs” couldn’t be saved in the folder “Library” because a
    file with the same name already exists.</p>
  </blockquote>
  
  <p>When /Logs dir is empty, simulator creates subdir CoreSimulator/[AppID]  and dispalys the above message. It's fresh OS X Yosemite, installed on new Mac Mini. </p>
  
  <p>Any idea how to fix this issue ?</p>
