I really want to look at React Native, but every time I pull up my Facebook app on my iPhone 6, it can take upwards of 30 seconds before the interface is useable.

That's on a very fast connection.

So to me the FB app is so slow, it makes me hesitant to give React Native much more thought as you'd figure the FB app would be THE showcase app for it.

Maybe I'm the only one?

Someone correct me if I'm wrong but AFAIK the Facebook app isn't really using react native yet, just in very small parts (event dashboard). The rest is still plain old swift and objc.

It's listed in the React Native showcase:

They have added quite a few screens on react native now. They don't use Swift at all right now.

this is correct

Last I'd heard, the Facebook app was still native per platform and not using React.

I wouldn't say you are the only one, but upwards of 30 seconds is very slow - I don't know anyone seeing that kind of performance. Perhaps try reinstalling?

I think I'll try that. Every time the lag happens I'm surprised by just how slow the app feels.
