title: Git doesn't show file as modified or let me commit in Xcode
body: <p>I am having this random problem with source control on Xcode. I already had Git integrated with my project, but now it's not recognizing that changes have been made to some files and won't let me commit them. </p>
  
  <p>The A never turns to M and the file does not get grayed out showing that it needs to be saved.</p>
