There&#x27;s a big exception to the automated checking. You can download new JavaScript code any time after your app is approved, as long as your app runs the code under the built-in WebKit. I don&#x27;t think there is any automated checking of what your new code does - how could there be? It&#x27;s just a violation of the terms of service if you change the app into something completely different:<p>&gt; 3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exception to the foregoing is scripts and code downloaded and run by Apple&#x27;s built-in WebKit framework or JavascriptCore, provided that such scripts and code do not change the primary purpose of the Application by providing features or functionality that are inconsistent with the intended and advertised purpose of the Application as submitted to the App Store.<p><a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;programs&#x2F;ios&#x2F;information&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;programs&#x2F;ios&#x2F;information&#x2F;</a><p><a href="http:&#x2F;&#x2F;info.meteor.com&#x2F;blog&#x2F;apple-hot-code-push-mobile" rel="nofollow">http:&#x2F;&#x2F;info.meteor.com&#x2F;blog&#x2F;apple-hot-code-push-mobile</a>
