When updating to the latest version of RN, the iOS build fails with the below message
fatal error: 'UIKit/UIDevice.h' file not found
#import <UIKit/UIDevice.h>
^~~~~~~~~~~~~~~~~~

"react": "16.13.1",
"react-native": "0.63.2",
"react-native-localization": "2.1.6",

It is working fine in
"react-native": "0.62",

Build fails only when I run in mac os using the below lib
https://github.com/microsoft/react-native-macos

This might be useful for the fix

We need this lib to support AppKit for macOS, But by default it uses UIKit as it is build only for mobile apps
