problems library react-native-contacts not working ios

I was testing an example from the react-native-contacts library in which I leave the link: https://github.com/morenoh149/react-native-contacts/tree/master/example

• git clone https://github.com/rt2zz/react-native-contacts.git
• cd react-native-contacts/example
• npm install
• cd ios && pod install && cd ..
• npx react-native run-ios

at the moment of running the example, a view is displayed with the supposed contacts that I have stored in ios but nothing can be displayed.

my problem is that I don't know what can be missing in the example from the same library, in android it works perfect. But the problem is ios in which it is not working.

please help.
