Open default phone Contacts app with Expo

Question

I'm using React Native Expo, and I want to open the default phone Contacts app.

On Android, I used:

await Linking.openURL("content://contacts/people/");

and that's worked.

On iOS that doesn't work.

I tried:

await Linking.openURL('contacts://');

but it doesn't work. How do I do that on IOS?

I want to open the contacts app on the iPhone only. Not getting contact data from the device through my app as suggested in some answers.

To open the default dialer app on iOS without a number pre-filled, you can try using the telprompt://{your number} URL scheme, which should prompt the dialer to open without immediately initiating a call. Here’s how you might use it in React Native

 import { Linking } from 'react-native';

// Function to open the dialer
const openDialer = async () => {
  const url = 'telprompt://<<your Number>>';
  const supported = await Linking.canOpenURL(url);

  if (supported) {
    await Linking.openURL(url);
  } else {
    console.log('Unable to open dialer');
  }
};
