However, Apple had not extended the feature to home screen web apps, so it was observed that web apps that are launched using the Home screen icon run much slower compared to when they’re launched directly in mobile Safari.
This prompted some publications to speculate that Apple was trying to cripple iPhone web apps.
Q: Did they fix the bug from 4.3 where home screen web apps don’t use Nitro?
A: This is probably breaking my NDA to say this, but yes, they did. Web.app now has the “dynamic-codesigning” entitlement, which enables Nitro.
Hopefully that puts an end to the conspiracy theory.
