I didn't find that to be the case with React Native in small to medium sized projects, so I personally wouldn't invest too much time into something that keeps you in only Apple's world, but I can def understand why it's appealing to iOS devs. IMO (and I know others might disagree), you shouldn't be building for JUST iOS in 2019 when on the web we always want to support as many users as possible.

I think being cross platform is the way forward for companies.
I think there is value in having knowledge of how to program for the native platform is good as well.
