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


Issues required to combine Push notification

Earlier than we leap 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 gadget – Push notification didn’t work on simulator
  • Apple developer account – Apple developer account is required as a way to run app on iPhone gadget and establishing Auth key or certificates on firebase app console.
  • App on Firebase.(You need to use your gmail account to create an app on Firebase )

Establishing app

First open up Xcode and create a fundamental challenge(in case you are utilizing an present challenge then open it up). First step is to activate push notification capabilities for our app. Comply with under steps to activate push notification functionality in your iOS app.

Steps to activate push functionality
  1. Choose your challenge 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 outcome displaying Push Notification.

Creating app on Firebase

  • Open https://firebase.google.com , and click on on Go to console or Sign up.
  • When you reached your Firebase console. Click on on Add Undertaking.
  • Enter your challenge identify. Click on Proceed.
  • Analytics is beneficial. Nevertheless it’s your alternative. For this tutorial, i made oi disabled.
  • Click on Create Undertaking. After few seconds Firebase challenge is created and you’re going to get message “Your new challenge 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 challenge(Proven in under image), and add it to Firebase app bundle if textbox.

The place to seek out bundle id in xcode challenge

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 non-compulsory. Subsequent we have to obtain .plist file supplied by Firebase and add that .plist named as “GoogleService-Information.plist” to your challenge. Lastly we have to add Firebase libraries to our xcode challenge. We are going to going to make use of cocoapods for our xcode challenge.

Putting in Firebase messaging pod

For this tutorial, we’re solely serious about 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 challenge (the place .xcodeproj file is situated)” Tip:- Merely click on on any file in your xcode challenge 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 challenge 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

Above code will initialize our Firebase object.

Requesting consumer permission for Push notification

Subsequent step is to request permissions from consumer 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 consumer 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’ll implement delegate that may give us gadget token. If you wish to know fundamental mechanism behind how push notification works in apple ecosystem then please examine under hyperlink


Getting gadget token

extension AppDelegate: UNUserNotificationCenterDelegate {
    func utility(_ utility: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Information) {
        Messaging.messaging().apnsToken = deviceToken
  	func utility(_ utility: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) 

Delegate named didRegisterForRemoteNotificationsWithDeviceToken, provides us distinctive token for the gadget which needs to obtain apple push notification. We are going to set this token to Firebase messaging apnsToken. You’ll be able to 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 gadget token.

Word:- Since Firebase by default use technique swizzling, so we have to flip it off if we need to get push as we’re mapping gadget token in IOS didRegisterForRemoteNotificationsWithDeviceToken delegate and never utilizing Firebase token handler. We will disable technique swizzling, by setting a key in information.plist file of our xcode challenge. Examine 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 consumer clicks on notification.
    func userNotificationCenter(_ middle: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
    func userNotificationCenter(_ middle: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 

Creating Auth key

Open https://developer.apple.com/account/ 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’d like 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 staff id you will discover your Staff ID within the Apple Member Middle underneath the membership tab

Including Auth key to Firebase challenge

Lastly we have to add auth key or push certificates to Firebase challenge. Go to your Firebase challenge, 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 underneath “APNs Authentication Key” part. Add auth key file created in final part, and key ID with staff ID in required fields. Click on add.

Take a look at Push notification

Run your app from xcode to actual iPhone gadget. Enable push notification and ship app to background. Now, open up Firebase challenge 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 Evaluate, a pop up will present up in your display screen. Click on Publish. Your gadget will obtain a push notification.
