title: How to find unused code in Xcode 7?
body: <p>I have seen <a href="https://stackoverflow.com/questions/1456966/how-to-detect-unused-methods-and-import-in-objective-c">this question</a>, but the answer doesn't seem to be valid in Xcode 7. At least I can't find it. </p>
  
  <p>Can anyone tell me where can I tell the compiler to notify me about unused functions/parameters/values ?</p>
