React Native Push Notification shows in XCode Console, but not on device

I have followed the guide on the react-native-push-notification documentation (https://github.com/zo0r/react-native-push-notification) to a T, but I'm unable to generate a simple notification when I load the app on my phone. Instead, I can see the notification in the XCode console. There are no errors otherwise.

var PushNotification = require('react-native-push-notification');

PushNotification.configure({

    // (optional) Called when Token is generated (iOS and Android)
    onRegister: function(token) {
        console.log( 'TOKEN:', token );
    },

    // (required) Called when a remote or local notification is opened or received
    onNotification: function(notification) {
        console.log( 'NOTIFICATION:', notification );

        // process the notification

        // required on iOS only (see fetchCompletionHandler docs: https://facebook.github.io/react-native/docs/pushnotificationios.html)
        notification.finish(PushNotificationIOS.FetchResult.NoData);
    },

    // ANDROID ONLY: GCM Sender ID (optional - not required for local notifications, but is need to receive remote push notifications)
    senderID: "YOUR GCM SENDER ID",

    // IOS ONLY (optional): default: all - Permissions to register.
    permissions: {
        alert: true,
        badge: true,
        sound: true
    },

    // Should the initial notification be popped automatically
    // default: true
    popInitialNotification: true,

    /**
      * (optional) default: true
      * - Specified if permissions (ios) and token (android and ios) will requested or not,
      * - if not, you must call PushNotificationsHandler.requestPermissions() later
      */
    requestPermissions: true,
});

export default class PostList extends Component<{}> 
{
    componentDidMount() {
        PushNotification.localNotification({
              /* Android Only Properties */
              id: '0', // (optional) Valid unique 32 bit integer specified as string. default: Autogenerated Unique ID

          });
