Is Xcode 9.4 supported? UIKit/UIUserActivity.h' file not found

[AnderLuiz]

The getting-started docs (https://facebook.github.io/react-native/docs/getting-started) says Xcode >= 9.4 is supported. But I always get a compilation error in 9.4 version:

UIKit/UIUserActivity.h' file not found

The issue (#25492) was closed because an update to Xcode 10.2 solved the problem, but it's not really a solution.

If not supported, I think the docs should be updated. If supported, the issue #25492 should be open again.

React Native version: 0.60

Steps To Reproduce

1. Follow the getting-started guide with Xcode 9.4 and Rn. 0.60

I still facing the issue with Xcode 9.4, but I installed Xcode 10.2 this way . I just downloaded the Xcode, edited the files and copied Xcode 10.2 to applications folder as 'Xcode'.

I was able to resolve this without upgrading my Xcode (thank god, still using 9.3).

For me, the reason is because the build terminal output showed that there were 3 packages that I had linked manually that I needed to unlink (via: react-native unlink PACKAGE-NAME) so that the autolinking could work.

After running that command for the 3 packages I had linked manually, I ran an npm install and react-native run-ios and everything worked.
