UIWebView was deprecated for years, everyone's had plenty of time to move to WKWebView, and it has nothing to do with React Native to boot.

Apple legitimately doesn't seem to care about hybrid frameworks, they've been there since day one. Any time it's seemed like it got difficult Apple has backed down. The lack of JIT in WKWebView is probably the only thing that you could stretch here.

WKWebView is out-of-process and has a JIT.

Ah, you're correct - not sure why I thought otherwise, especially when I touch WKWebView pretty often.

Perhaps you confused it with JavaScriptCore?

Hmmm, possibly. Either way thanks for the catch!

Printing still sucked pretty bad in WKWebView the last time I looked into it (which admittedly has been a year or two, so maybe that's been fixed).
