title: "Find Call Hierarchy" not working in Xcode (big project with cocoapods)
body: <p>I'm trying to maintain a huge iOS project which has more than a hundred of classes and cocoapods as dependence manager. </p>
  
  <p>When I try to do a "Find Call Hierarchy" on a function which has some uses, it doesn't show the uses of the function. Instead of showing anything, it plays a "beep" sound. No errors displayed.</p>
  
  <p>Maybe it's necessary to configure something in Xcode? maybe it's a bug on Xcode last version?</p>
