title: Code Sign Error When Building iPhone Application
body: <p>I am new to iPhone development. I just registered with Apple for the iPhone Developer Program. When I try to build, I am receiving an error:</p>
  
  <blockquote>
    <p>Code Sign error: a valid provisioning profile matching the application’s identifier could not be found</p>
  </blockquote>
  
  <p>I'm not sure what is wrong. I tried browsing the Internet but I get confused. Can anyone help me with what I should do?</p>
