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

• pod set up
• After profitable set up shut your present xcode mission and reopen it with double faucet on file title having extension .xcworkspace

Open AppDelegate.swift and add under code

import UIKit
import FirebaseCore
import FirebaseMessaging

@predominant
class AppDelegate: UIResponder, UIApplicationDelegate {

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

import UIKit
import FirebaseCore
import FirebaseMessaging

@predominant
class AppDelegate: UIResponder, UIApplicationDelegate {

    func software(_ software: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalization after software 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
            }
        }
        software.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 are going to implement delegate that may give us machine token. If you wish to know primary mechanism behind how push notification works in apple ecosystem then please test under hyperlink

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

Getting machine token

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

Delegate named didRegisterForRemoteNotificationsWithDeviceToken, offers us distinctive token for the machine which desires 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 machine token.

Observe:- Since Firebase by default use methodology swizzling, so we have to flip it off if we wish to get push as we’re mapping machine token in IOS didRegisterForRemoteNotificationsWithDeviceToken delegate and never utilizing Firebase token handler. We will disable methodology swizzling, by setting a key in information.plist file of our xcode mission. Test 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(_ heart: 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(_ heart: 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’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 group id yow will discover your Staff ID within the Apple Member Heart below the membership tab

Including Auth key to Firebase mission

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

Take a look at Push notification

Run your app from xcode to actual iPhone machine. Permit push notification and ship app to background. Now, open up Firebase mission 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 Assessment, a pop up will present up in your display screen. Click on Publish. Your machine will obtain a push notification.

The place to go from right here

On this tutorial, we realized the best way to combine push notification in iOS app utilizing Firebase cloud messaging in swift. We lined all steps from begin to finish the place we acquired a push notification from Firebase. In case you are on the lookout for video tutorial for identical then go to under hyperlink
