Step 2: Configure Your iOS Project in Xcode
Next, set up your iOS app to handle FCM and APN push notifications.
- Install Firebase SDK:
- In your iOS project's Podfile, add the Firebase dependencies:
pod 'Firebase/Messaging'
- Run pod install to integrate Firebase Messaging into your app.
- Enable Push Notifications:
- In Xcode, select your project in the Project Navigator.
- Under your app’s target, click on Signing & Capabilities.
- Add Push Notifications and Background Modes. Under Background Modes, check the "Remote notifications" option.
- Configure AppDelegate for Firebase: You need to initialize Firebase and handle APN registration within the AppDelegate.
import UIKit
import Firebase
import FirebaseMessaging
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
// Register for remote notifications
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(options: authOptions, completionHandler: { _, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
}
}
- Handle FCM Notifications: Create a delegate method to handle incoming messages from Firebase.
extension AppDelegate: UNUserNotificationCenterDelegate, MessagingDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .badge, .sound])
}
// Handle FCM token refresh.
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
print("FCM Token: \(fcmToken ?? "")")
// TODO: If necessary, send the token to your server.
}
}
