title: Instruments stopped working on iPhone apps
body: <p>I had used Instruments tool (an Xcode developer tool) to analyze iOS applications before with no issues. But now when I try to run it on any iOS app (for instance CNN), it is giving me following error. </p>
  
  <p>"Target failed to run: Permission to debug com.cnn.iphone was denied. The app must be signed with a development identity (e.g. iOS Developer)."</p>
  
  <p>Is there any work around? Is it not supported anymore in new version of Xcode? Few months ago, I was able to use it on all applications including CNN.  </p>
