Good q. All of it is still Objective C and C++; there's a few blockers to starting to move to Swift, including the relatively large amount of custom build + development tooling that we and FB have in place.

Hi Mike, since Instagram is listed in the React Native Showcase, could you tell us where are you using it? Thanks in advance.

It's getting used more and more in our app--few recent examples are the "Promote Post" UI if you're a business account and want to promote a post from inside Instagram, the Saved Posts feature, and the comment moderation tools we now provide around comment filtering.

I'd like to know this, too.
