I'm quite surprised that @jadhavrahul10's comment has marked as off-topic. I got the same compiler errors (not using warnings here as they actually made the build fail). After some searches, I saw this issue but seems no solution.

And after some time of futile efforts, I somehow went back to this post again. Find there's a tiny hidden comment. Moreover, after upgrading the Xcode, it did solve the issue.

Sorry that I'm not an experienced developer on React-native, so I'm not 100% sure if that is the right solution. Just leave this message in case anyone has the same problem, you can give it a try.

Strange - I'm not sure why that was off topic.
I can say this though: if you develop for iOS, keep your Xcode up to date. It's a baseline expectation (even though it is a monstrously large download...)
