The secret to app submission in XCode 4

This will only be a short post. After 2+ days of intensive googling and debugging, I finally got past the "Invalid Binary" error message. All it was had to do with the the submission of the app in Organizer. You choose the app, but you also have to choose a profile. I was letting it default to the developer's profile, when I should have chosen the distribution profile. That was it, I believe. Now, how difficult would it have been to send out an error message stating "app does not match profile selected in app submission process." It would have save me a ton of grief.
