react-native-ios11-devicecheck (RNIOS11DeviceCheck)

React Native implementation for Apple iOS 11 DeviceCheck DCDevice API. Except iOS platform always comes on Promise.reject('Other than iOS platform not supported')

Uses:

• webservice request on server comes from apple devices.
• App device token using device check is ephemeral, but that token is useful to identify the device uniqueness such as per device per app one offer scenario. If device formatted, keychain wipe or any hack won't effect on this case. Safe to check per device identification.

Installation: (npm)

$ npm i --save react-native-ios11-devicecheck

Implemtation (iOS Only using cocoapods, no need to do anything on android):

pod 'RNIOS11DeviceCheck', :path => '../node_modules/react-native-ios11-devicecheck/ios'

Try inside javascript code: index.js

import React from 'react';
import { View } from 'react-native';
import RNIOS11DeviceCheck from 'react-native-ios11-devicecheck';

export default class App extends React.Component {
	componentDidMount = () => {
		RNIOS11DeviceCheck
			.getToken()
			.then(console.warn)
			.catch(console.warn);
	};

	render = () => <View style={{ flex: 1, backgroundColor: 'white' />;
}
