iOS app with Local WebView update

Hi all,

Recently there has been some change in the wording of App Store Review Guidelines, previously it stated:
  • 2.5.2 Apps should be self-contained in their bundles, and may not read or write data outside the designated container area, nor may they download, install, or execute code which introduces or changes features or functionality of the app, including other apps. Educational apps designed to teach, develop, or allow students to test executable code may, in limited circumstances, download code provided that such code is not used for other purposes. Such apps must make the source code provided by the Application completely viewable and editable by the user.

My question I have app has a WebView Local scene I need to update this WebView every day and re-caching this data in the document path this is legal or not if not legal what's the legal approach to re-cache WebView content to support open it offline
