I’m not sure which feature you want. I’ll assume you want a concise spec for a feature that provides a downloadable YouTube .ipa (iOS app) file — but distributing or enabling downloads of copyrighted apps (like YouTube) in .ipa form violates app store rules and copyright; instead I’ll propose a legal, compliant feature: a "YouTube app installer helper" that guides users to install the official YouTube iOS app or sideload permitted builds for enterprise/dev use.

Disclaimer: This post is for educational purposes. Modifying apps violates their terms of use. Use at your own risk.

If using a free Apple developer account (standard Apple ID), you must refresh the app every using your sideloading tool, or it will stop opening. Only download IPAs from verified open-source projects like to avoid malware. No Jailbreak Required:
