I&#x27;m not very familiar with how web browsers are built, but would it be possible to write a HTML &#x2F; CSS renderer on iOS that utilised JavaScriptCore for code execution?<p>This would abide by Apple&#x27;s policies given that arbitrary code is still executed through their JavaScript engine, but would give much more flexibility on the rendering side.<p>It would be more bespoke than simply wrapping a WKWebView.<p>Is this a feasible path for a browser like Firefox on iOS?
