Combine push notification utilizing Firebase messaging in swift – iOS swift tutorial – iOSTutorialJunction

Issues required to combine Push notification

Earlier than we soar on to combine push notification utilizing Firebase messaging in iOS swift, you want few issues at your disposal to check iOS push notification. Under is the listing of issues required to combine and examine push notification integration in iOS.

  • iPhone system – Push notification didn’t work on simulator
  • Apple developer account – Apple developer account is required so as to run app on iPhone system and establishing Auth key or certificates on firebase app console.
  • App on Firebase.(You should use your gmail account to create an app on Firebase )

Establishing app

First open up Xcode and create a primary venture(if you’re utilizing an present venture then open it up). First step is to activate push notification capabilities for our app. Observe under steps to activate push notification functionality in your iOS app.

Steps to activate push functionality
  1. Choose your venture identify. See image for reference
  2. Choose your app goal. Choose Signing and capabilities.
  3. Click on on + Functionality.
  4. Seek for Push notification and click on on searched consequence exhibiting Push Notification.

Creating app on Firebase

  • Open , and click on on Go to console or Register.
  • When you reached your Firebase console. Click on on Add Undertaking.
  • Enter your venture identify. Click on Proceed.
  • Analytics is really useful. But it surely’s your selection. For this tutorial, i made oi disabled.
  • Click on Create Undertaking. After few seconds Firebase venture is created and you’ll get message “Your new venture is prepared,”. Click on on proceed.
  • Click on on iOS icon to start out process of including Firebase to your iOS app.

Including Firebase to iOS app

Copy bundle identifier from xcode venture(Proven in under image), and add it to Firebase app bundle if textbox.

The place to search out bundle id in xcode venture

You may give nick identify to your app on Firebase and may add app retailer id for the app (if added to apple join). Each of those steps are optionally available. Subsequent we have to obtain .plist file supplied by Firebase and add that .plist named as “GoogleService-Information.plist” to your venture. Lastly we have to add Firebase libraries to our xcode venture. We’ll going to make use of cocoapods for our xcode venture.

You’ll find listing of firebase pods from this hyperlink

Putting in Firebase messaging pod

For this tutorial, we’re solely focused on Firebase messaging pod. Since we’re solely integrating push notification with Firebase in IOS.

  • Open terminal and sort command
  • cd “path root listing of your venture (the place .xcodeproj file is positioned)” Tip:- Merely click on on any file in your xcode venture and click on present in finder
  • pod init
  • open -e podfile
  • As soon as podfile is opened in TextEdit paste under line to it, Save file and go t o terminal window
  • pod set up
  • After profitable set up shut your present xcode venture and reopen it with double faucet on file identify having extension .xcworkspace

Open AppDelegate.swift and add under code

import UIKit
import FirebaseCore
import FirebaseMessaging

class AppDelegate: UIResponder, UIApplicationDelegate {

    func utility(_ utility: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalization after utility launch.
        return true

Above code will initialize our Firebase object.

Requesting person permission for Push notification

Subsequent step is to request permissions from person for the push notification. Add under code to your utility: didFinishLaunchingWithOptions technique.

import UIKit
import FirebaseCore
import FirebaseMessaging

class AppDelegate: UIResponder, UIApplicationDelegate {

    func utility(_ utility: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalization after utility launch.
        UNUserNotificationCenter.present().delegate = self
        let authOptions: UNAuthorizationOptions = [.alert, .sound,.badge]
        UNUserNotificationCenter.present().requestAuthorization(choices: authOptions) { success, error in
            if error != nil {
                //we're able to go
        return true

In above code, we use UserNotificationCentre to request person to permit push notification having permissions for alert, sound and badge.

Conforming to UNUserNotificationCenterDelegate protocol

We have to implement delegates required for Push notification. First we are going to implement delegate that may give us system token. If you wish to know primary mechanism behind how push notification works in apple ecosystem then please examine under hyperlink

Getting system token

extension AppDelegate: UNUserNotificationCenterDelegate {
    func utility(_ utility: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Information) {
        Messaging.messaging().apnsToken = deviceToken
  	func utility(_ utility: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Didn't register with push")

Delegate named didRegisterForRemoteNotificationsWithDeviceToken, offers us distinctive token for the system which desires to obtain apple push notification. We’ll set this token to Firebase messaging apnsToken. You possibly can ship this apns token to your server in case your server is sending notifications to you. Second delegate, named didFailToRegisterForRemoteNotificationsWithError will will get known as if we fail to get system token.

Observe:- Since Firebase by default use technique swizzling, so we have to flip it off if we wish to get push as we’re mapping system token in IOS didRegisterForRemoteNotificationsWithDeviceToken delegate and never utilizing Firebase token handler. We are able to disable technique swizzling, by setting a key in data.plist file of our xcode venture. Test under picture.

Turning off Firebase technique swizzling

Including UNUserNotificationCenterDelegate

UNUserNotificationCenterDelegate has two delegates that we have to implement

  • willPresent notification :- This delegate will will get known as as soon as we obtain push notification and our app is in foreground.
  • didReceive response:- This delegate will will get known as when person clicks on notification.
    func userNotificationCenter(_ middle: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("Will will get known as when app is in forground and we wish to present banner")

        completionHandler([.alert, .sound, .badge])
    func userNotificationCenter(_ middle: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("Will will get known as when person faucet on notifictaion")

Creating Auth key

Open and choose Certificates, identifiers and profiles choice. On left menu click on on auth key choice. Create it and obtain it to secure place as we want this key file in subsequent step, all steps are self explanatory. As soon as your authkey is generated by apple, copy “Key ID”. Lastly, we required group id you could find your Group ID within the Apple Member Heart beneath the membership tab

Including Auth key to Firebase venture

Lastly we have to add auth key or push certificates to Firebase venture. Go to your Firebase venture, and click on on gear icon on high left nook. Choose “Undertaking Settings” -> “Cloud Messaging” -> Scroll right down to IOS app and click on on “Add” button beneath “APNs Authentication Key” part. Add auth key file created in final part, and key ID with group ID in required fields. Click on add.

Check Push notification

Run your app from xcode to actual iPhone system. Permit push notification and ship app to background. Now, open up Firebase venture and discover “Cloud Messaging” from left menu. Click on on it. If this your first message you will notice button having textual content “Ship you first message”. Fill within the required type .Click on Evaluation, a pop up will present up in your display screen. Click on Publish. Your system will obtain a push notification.
