title: Debugging share extension on iphone not working
body: <p>I'm trying to develop an application with a shared extension. I ran into an issue while attempting to debug my app on an iPhone. I receive an error message "could not attach to pid : unable to attach"; but on a simulator everything works fine.</p>
  
  <p>I tried attaching to the process via Debug>Attack by PID or by Name, but nothing changed.
  Am I doing something wrong? How should I proceed?</p>
  
  <p>Thank you and regards, Milan.</p>
