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

• 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

@major
class AppDelegate: UIResponder, UIApplicationDelegate {

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

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

@major
class AppDelegate: UIResponder, UIApplicationDelegate {

    func utility(_ utility: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalization after utility launch.
        FirebaseApp.configure()
        
        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
            }
        }
        utility.registerForRemoteNotifications()
        
        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 system token. If you wish to know fundamental mechanism behind how push notification works in apple ecosystem then please examine under hyperlink

https://stackoverflow.com/questions/17262511/how-do-ios-push-notifications-work

Getting system token

extension AppDelegate: UNUserNotificationCenterDelegate {
    func utility(_ utility: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Knowledge) {
        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 needs 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 need 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 information.plist file of our xcode venture. Examine under picture.

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) {
        print("Will will get known as when app is in forground and we need 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 consumer faucet on notifictaion")
        completionHandler()
    }
}

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 protected 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 staff id you could find your Workforce ID within the Apple Member Middle 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 all the way 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 staff 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 kind .Click on Evaluate, a pop up will present up in your display screen. Click on Publish. Your system will obtain a push notification.

The place to go from right here

On this tutorial, we realized methods to combine push notification in iOS app utilizing Firebase cloud messaging in swift. We coated all steps from begin to finish the place we obtained a push notification from Firebase. In case you are searching for video tutorial for identical then go to under hyperlink
