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 record of issues required to combine and verify push notification integration in iOS.
- iPhone system – Push notification didn’t work on simulator
- Apple developer account – Apple developer account is required with a purpose to run app on iPhone system and organising Auth key or certificates on firebase app console.
- App on Firebase.(You should use your gmail account to create an app on Firebase )
Organising app
First open up Xcode and create a primary mission(in case you are utilizing an current mission then open it up). First step is to activate push notification capabilities for our app. Comply with beneath steps to activate push notification functionality in your iOS app.
- Choose your mission identify. See image for reference
- Choose your app goal. Choose Signing and capabilities.
- Click on on + Functionality.
- Seek for Push notification and click on on searched end result displaying Push Notification.
Creating app on Firebase
- Open https://firebase.google.com , and click on on Go to console or Register.
- When you reached your Firebase console. Click on on Add Challenge.
- Enter your mission identify. Click on Proceed.
- Analytics is really useful. Nevertheless it’s your selection. For this tutorial, i made oi disabled.
- Click on Create Challenge. After few seconds Firebase mission is created and you’re going to get message “Your new mission is prepared,”. Click on on proceed.
- Click on on iOS icon to begin process of including Firebase to your iOS app.
Including Firebase to iOS app
Copy bundle identifier from xcode mission(Proven in beneath image), and add it to Firebase app bundle if textbox.
You can provide nick identify to your app on Firebase and might add app retailer id for the app (if added to apple join). Each of those steps are non-obligatory. Subsequent we have to obtain .plist file offered by Firebase and add that .plist named as “GoogleService-Data.plist” to your mission. Lastly we have to add Firebase libraries to our xcode mission. We’ll going to make use of cocoapods for our xcode mission.
Yow will discover record of firebase pods from this hyperlink https://firebase.google.com/docs/ios/setup?authuser=0
Putting in Firebase messaging pod
For this tutorial, we’re solely involved in Firebase messaging pod. Since we’re solely integrating push notification with Firebase in IOS.
- Open terminal and kind command
- cd “path root listing of your mission (the place .xcodeproj file is situated)” Tip:- Merely click on on any file in your xcode mission and click on present in finder
- pod init
- open -e podfile
- As soon as podfile is opened in TextEdit paste beneath line to it, Save file and go t o terminal window
- pod set up
- After profitable set up shut your current xcode mission and reopen it with double faucet on file identify having extension .xcworkspace
Open AppDelegate.swift and add beneath code
import UIKit
import FirebaseCore
import FirebaseMessaging
@foremost
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 consumer permission for Push notification
Subsequent step is to request permissions from consumer for the push notification. Add beneath code to your software: didFinishLaunchingWithOptions technique.
import UIKit
import FirebaseCore
import FirebaseMessaging
@foremost
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 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 can give us system token. If you wish to know primary mechanism behind how push notification works in apple ecosystem then please verify beneath 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("Did not 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 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 are able to disable technique swizzling, by setting a key in information.plist file of our xcode mission. Examine beneath 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 consumer clicks on notification.
func userNotificationCenter(_ middle: 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(_ middle: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("Will will get referred to 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 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 workforce id you could find your Group ID within the Apple Member Middle beneath 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 high left nook. Choose “Challenge 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 workforce ID in required fields. Click on add.
Check Push notification
Run your app from xcode to actual iPhone system. Enable 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 type .Click on Assessment, a pop up will present up in your display screen. Click on Publish. Your system will obtain a push notification.

We coated all steps from begin to finish the place we acquired a push notification from Firebase. If you’re in search of video tutorial for identical then go to beneath hyperlink
