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

• pod set up
• After profitable set up shut your current xcode challenge 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

@important
class AppDelegate: UIResponder, UIApplicationDelegate {

    func software(_ software: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalisation after software launch.
        FirebaseApp.configure() 
        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 software: didFinishLaunchingWithOptions technique.

import UIKit
import FirebaseCore
import FirebaseMessaging

@important
class AppDelegate: UIResponder, UIApplicationDelegate {

    func software(_ software: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override level for personalisation 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 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 can give us system token. If you wish to know primary 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 software(_ software: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Knowledge) {
        Messaging.messaging().apnsToken = deviceToken
    }
  
  	func software(_ software: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Didn't register with push")
    }
}

Delegate named didRegisterForRemoteNotificationsWithDeviceToken, provides us distinctive token for the system which desires to obtain apple push notification. We’ll 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 referred to as if we fail to get system token.

Be aware:- 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 will disable technique swizzling, by setting a key in data.plist file of our xcode challenge. Verify under picture.

Including UNUserNotificationCenterDelegate

UNUserNotificationCenterDelegate has two delegates that we have to implement

• willPresent notification :- This delegate will will get referred to as as soon as we obtain push notification and our app is in foreground.
• didReceive response:- This delegate will will get referred to as when person clicks on notification.

    func userNotificationCenter(_ heart: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("Will will get referred to 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 referred to as when person 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 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 workforce id yow will discover your Group ID within the Apple Member Heart beneath 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 “Challenge 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 workforce 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 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 Overview, a pop up will present up in your display. Click on Publish. Your system will obtain a push notification.
