title: iOS Apple Developer App Guidelines
body: <p>I've read through <a href="https://developer.apple.com/app-store/review/guidelines/#functionality" rel="nofollow">Apple's iOS app submission guidelines</a>, although my question is more in regards to the rules (if applicable) after it's been approved.</p>
  
  <p>Basically what I'd like to know is if a developer is allowed disable certain functionality in an older version of an app so that the user is essentially forced to upgrade to a newer version? This could also include making the user download another completely separate app (that the functionality was previously in the old version) in the process.</p>
  
  <p>Is this allowable, or is there something that specifically says that's against the guidelines/rules? If anyone knows the answer to this and could provide the source of the info that would be great. thx.</p>
