title: Xcode 4 says "finished running <my app>" on the targeted device -- Nothing happens
body: <p>The app neither installs nor runs on my device. All provisioning profiles are up to date. I've already tried deleting and re-installing them.</p>
  
  <p>The status bar shows that Xcode is building my project, then it says running my project on , then it says "finished running ."  Throughout this entire period, the iPod screen stays black. The iPod is being detected in the Organizer and I don't see anything wrong with its configuration. Everything was working perfectly just a couple days ago with Xcode 3.</p>
  
  <p>It doesn't work on the simulator, but it may be important to note that in the simulator it appears to get stuck on "Attaching to " and the simulator refuses to start.</p>
