I've had a similar experience. I have had to spend time learning both, I think I am just paranoid about job security! Moving from Objective-C to Swift felt a lot more natural than moving to React Native, getting used to Javascript and the web development environment in general is quite daunting. What were your deciding factors when making your decision?

I think job security was one of my decisions too. Another important decision was the fact that I wanted to be able to use React for both web and mobile apps. Mastering JS was a big bonus.

That being said, it's definitely a smart move to invest time in swift (I did play around with some swift libraries), as it does seem the industry "might" move towards some kind of hybrid obj-c and/or swift + React-native app. I've personally decided to invest more time in JS than Swift.

Yes, the React syntax and JS in general also wasn't as easy for me to catch on vs. obj-c (I wrote a lot of C in my previous job). As you write more, you'll get use to it.
