Sign In with Apple in React Native

SignIn with Apple

Using Apple Authentication in a React Native application involves a few steps, including setting up your Xcode project, configuring your Apple Developer account, and implementing the authentication flow in your React Native code.

Below is a simple example to get you started. Note that you need to have Xcode installed on your macOS machine to build and run the iOS application.

Step 1: Set up your Xcode project

Make sure your Xcode project is properly configured. You can do this by opening your Xcode project and ensuring that you have a valid bundle identifier, signing capabilities, and an Apple Developer account linked to your project.

Step 1: Set up your Xcode project

Make sure your Xcode project is properly configured. You can do this by opening your Xcode project and ensuring that you have a valid bundle identifier, signing capabilities, and an Apple Developer account linked to your project.

Step 2: Configure your Apple Developer account

1. Go to the Apple Developer portal, create an App ID, and configure Sign In with Apple for your app.
2. Create a Services ID with Sign In with Apple enabled.
3. Configure your Xcode project with the App ID and Services ID.

Go to the Apple Developer website and log in with your Apple ID.

1. Click on “Certificates, IDs & Profiles” in the left sidebar.
2. Under the “Identifiers” section, click on “App IDs”.

4. Find the App ID for your app and click on it.

5. Scroll down to the “Sign In with Apple” section and click on “Configure”.

SignIn with Apple ID

6. Choose the primary and secondary app’s language.

7. Select any domains that your app may use for authentication callbacks.

8. Choose the appropriate primary and secondary category for your app.

9. In the “Add capability” section, you can select which of your apps will be using “Sign In with Apple”.

10. After that, click on the “Continue” button to review the information you have entered.

11. If everything looks correct, click on the “Register” button.

12. Finally, in your Xcode project, go to the “Signing & Capabilities” tab, and enable “Sign In with Apple” capability.

Enable “Sign In with Apple” capability in Xcode :

1. Open your Xcode project.
2. Go to the “Signing & Capabilities” tab.
3. Click on the “+” button to add a new capability.
4. Select “Sign In with Apple” from the list of capabilities.
5. Make sure that the “App ID” selected in the dropdown menu matches the App ID you created in the Apple Developer portal.
6. If you have enabled any domains for authentication callbacks in the Apple Developer portal, make sure to add them to the “Domains” section in Xcode.
7. Save your changes.

Step 3: Install dependencies

Make sure you have the necessary dependencies installed:

npm install @react-native-community/apple-authentication

Step 4: Implement Apple Authentication in React Native

Create a new React Native component or modify an existing one. For this example, let’s create a simple button that triggers Apple Authentication:

// Import necessary modules
import React from 'react';
import { View, Button, Alert } from 'react-native';
import appleAuth, { AppleAuthRequestOperation, AppleAuthRequestScope } from '@react-native-community/apple-authentication';

const App = () => {
  const handleAppleLogin = async () => {
    try {
      const appleAuthRequestResponse = await appleAuth.performRequest({
        requestedOperation: AppleAuthRequestOperation.LOGIN,
        requestedScopes: [AppleAuthRequestScope.EMAIL, AppleAuthRequestScope.FULL_NAME],
      });

      const { email, fullName, identityToken, realUserStatus /* etc */ } = appleAuthRequestResponse;

      // Use the user details as needed
      Alert.alert('Apple Login Success', `Email: ${email}, FullName: ${fullName}, IdentityToken: ${identityToken}, RealUserStatus: ${realUserStatus}`);
    } catch (error) {
      console.log('Apple Login Error:', error);
      Alert.alert('Apple Login Failed', 'An error occurred during Apple Login.');
    }
  };

  return (
    <View>
      <Button title="Login with Apple" onPress={handleAppleLogin} />
    </View>
  );
};

export default App;

Step 5: Run your React Native app

Make sure your iOS simulator or device is ready, then run your React Native app:

npx react-native run-ios

Step 2: Configure your Apple Developer account

1. Go to the Apple Developer portal and create an App ID and configure Sign In with Apple for your app.
2. Create a Services ID with Sign In with Apple enabled.
3. Configure your Xcode project with the App ID and Services ID.

Step 3: Install dependencies

Make sure you have the necessary dependencies installed:

bashCopy code

npm install @react-native-community/apple-authentication

Step 4: Implement Apple Authentication in React Native

Create a new React Native component or modify an existing one. For this example, let’s create a simple button that triggers Apple Authentication:

jsxCopy code

// Import necessary modules
import React from 'react';
import { View, Button, Alert } from 'react-native';
import appleAuth, { AppleAuthRequestOperation, AppleAuthRequestScope } from '@react-native-community/apple-authentication';

const App = () => {
  const handleAppleLogin = async () => {
    try {
      const appleAuthRequestResponse = await appleAuth.performRequest({
        requestedOperation: AppleAuthRequestOperation.LOGIN,
        requestedScopes: [AppleAuthRequestScope.EMAIL, AppleAuthRequestScope.FULL_NAME],
      });
      const { email, fullName, identityToken, realUserStatus /* etc */ } = appleAuthRequestResponse;
      // Use the user details as needed
      Alert.alert('Apple Login Success', `Email: ${email}, FullName: ${fullName}, IdentityToken: ${identityToken}, RealUserStatus: ${realUserStatus}`);
    } catch (error) {
      console.log('Apple Login Error:', error);
      Alert.alert('Apple Login Failed', 'An error occurred during Apple Login.');
    }
  };
  return (
    <View>
      <Button title="Login with Apple" onPress={handleAppleLogin} />
    </View>
  );
};
export default App;

Step 5: Run your React Native app

Make sure your iOS simulator or device is ready, then run your React Native app:

bashCopy code

npx react-native run-ios

This example provides a basic setup for Apple Authentication in a React Native app. Depending on your app’s requirements, you might need to handle more complex scenarios, such as linking accounts or refreshing tokens
