Badge variable is missing in my FCM notification in Swift - swift

I am receiving notifications in my app using FCM but i am unable to show badge count on my app icon since there seems to be missing variables in my notification. how can i add this?
Below is the error i am getting
[AnyHashable("icon"): logo.png, AnyHashable("user_id"): 3, AnyHashable("google.c.sender.id"): 938224596608, AnyHashable("aps"): {
alert = {
body = "You have new message! Check in the app.";
title = Tutil;
};
sound = default;
}, AnyHashable("google.c.a.e"): 1, AnyHashable("body"): You have new message! Check in the app., AnyHashable("user_photo"): images/3.png, AnyHashable("type"): message, AnyHashable("gcm.message_id"): 1604897386664267, AnyHashable("title"): Tutil, AnyHashable("user_name"): Mali, AnyHashable("lessons"): []]
Below is my code
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
print("%#", userInfo)
// Print message ID.
let content = notification.request.content
let badgeCount = content.badge as! Int //<<i am getting my error here as variables may not be available
incrementBadgeNumberBy(badgeNumberIncrement: badgeCount)
completionHandler([.alert,.badge,.sound])
}

You can get badge like this
if let aps = userInfo["aps"] as? Dictionary<String, Any>, let badge = aps["badge"] as? Int {
print(badge)
}

Unit Testing UNUserNotificationCenterDelegate Methods

I'd like to unit test some UNUserNotificationCenterDelegate methods, especially userNotificationCenter(_, willPresent:, withCompletionHandler:)
To do that, I'd have to create an instance of UNNotification, but that's not really possible because it only has an initWithCoder initializer. What to do?
This is an example of what I'd like to test:
func userNotificationCenter(
_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void
) {
completionHandler(.sound)
}
Thanks to this README and the private iOS headers here, I came up with this solution:
func testUserNotificationCenterDelegate() throws {
// Create the notification content
let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Test"
notificationContent.userInfo = ["someKey": "someValue"]
// Create a notification request with the content
let notificationRequest = UNNotificationRequest(identifier: "test", content: notificationContent, trigger: UNTimeIntervalNotificationTrigger(timeInterval: 0.1, repeats: false))
// Use private method to create a UNNotification from the request
let selector = NSSelectorFromString("notificationWithRequest:date:")
let unmanaged = UNNotification.perform(selector, with: notificationRequest, with: Date())
let notification = unmanaged?.takeUnretainedValue() as! UNNotification
// Test the method
let callbackExpectation = XCTestExpectation(description: "Callback")
pushService.userNotificationCenter(UNUserNotificationCenter.current(), willPresent: notification) { (options) in
XCTAssertEqual(options, .sound)
callbackExpectation.fulfill()
}
wait(for: [callbackExpectation], timeout: 2.0)
}
In the code above, pushService is an instance of a class that conforms to the UNUserNotificationCenterDelegate protocol. Elsewhere in my code, I set that instance as the center's delegate: UNUserNotificationCenter.current().delegate = pushService.
Enjoy!
You can use class_createInstance(UNNotification.classForKeyedArchiver() ...)and cast the value as UNNotification
If you want to manipulate its content and date members you can subclass UNNotification and use this same formula «changing class name and cast» to create it, then you override those members- which are open- and return whatever you want

Trying to customize notifications in macOS with Swift

I am using macOS 10.5.6 and I am trying to display a custom notification. I am using UNNotificationAction to set up a drop down menu for the notification and UNNotificationCategory to save it. I can get the notification correctly. The title and body are displayed but the popup menu for the notification is displayed under a button labeled "Actions".
What I would like to happen is have the label "Actions" changed to a two button format the way that the Reminders app does. I have spent a couple of days searching this web site and several others trying to find the answer but all I have found is the method I am currently using to set up the notification with out the button format that I would like to display. I know that it can be done I just do not know which key words to use to get the answer I would appreciate any help I can get.
enter image description here
Sample notifications
A notification with an attachment:
A notification with an attachment, mouse is hovering over to make the action buttons visible (they're visible right away if there's no attachment).
Sample project
Delegate
AppDelegate is going to handle notifications in the following sample project. We have to make it conform to the UNUserNotificationCenterDelegate protocol.
import UserNotifications
#NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate, UNUserNotificationCenterDelegate {
...
}
We have to set the UNUserNotificationCenter.delegate to our AppDelegate in order to receive notifications. It must be done in the applicationDidFinishLaunching: method.
func applicationDidFinishLaunching(_ aNotification: Notification) {
setupNotificationCategories() // See below
UNUserNotificationCenter.current().delegate = self
// Other stuff
}
Authorization, capabilities, ... omitted for simplicity.
Constants
An example how to avoid hardcoded constant.
enum Note {
enum Action: String {
case acceptInvitation = "ACCEPT_INVITATION"
case declineInvitation = "DECLINE_INVITATION"
var title: String {
switch self {
case .acceptInvitation:
return "Accept"
case .declineInvitation:
return "Decline"
}
}
}
enum Category: String, CaseIterable {
case meetingInvitation = "MEETING_INVITATION"
var availableActions: [Action] {
switch self {
case .meetingInvitation:
return [.acceptInvitation, .declineInvitation]
}
}
}
enum UserInfo: String {
case meetingId = "MEETING_ID"
case userId = "USER_ID"
}
}
Setup categories
Make the notification center aware of our custom categories and actions. Call this function in the applicationDidFinishLaunching:.
func setupNotificationCategories() {
let categories: [UNNotificationCategory] = Note.Category.allCases
.map {
let actions = $0.availableActions
.map { UNNotificationAction(identifier: $0.rawValue, title: $0.title, options: [.foreground]) }
return UNNotificationCategory(identifier: $0.rawValue,
actions: actions,
intentIdentifiers: [],
hiddenPreviewsBodyPlaceholder: "",
options: .customDismissAction)
}
UNUserNotificationCenter.current().setNotificationCategories(Set(categories))
}
Create a notification content
Sample notification content with an attachment. If we fail to create an
attachment we will continue without it.
func sampleNotificationContent() -> UNNotificationContent {
let content = UNMutableNotificationContent()
content.title = "Hey Jim! Weekly Staff Meeting"
content.body = "Every Tuesday at 2pm"
content.userInfo = [
Note.UserInfo.meetingId.rawValue: "123",
Note.UserInfo.userId.rawValue: "456"
]
content.categoryIdentifier = Note.Category.meetingInvitation.rawValue
// https://developer.apple.com/documentation/usernotifications/unnotificationattachment/1649987-init
//
// The URL of the file you want to attach to the notification. The URL must be a file
// URL and the file must be readable by the current process. This parameter must not be nil.
//
// IOW We can't use image from the assets catalog. You have to add an image to your project
// as a resource outside of assets catalog.
if let url = Bundle.main.url(forResource: "jim#2x", withExtension: "png"),
let attachment = try? UNNotificationAttachment(identifier: "", url: url, options: nil) {
content.attachments = [attachment]
}
return content
}
Important: you can't use an image from the assets catalog, because you need an URL pointing to a file readable by the current process.
Trigger helper
Helper to create a trigger which will fire a notification in seconds seconds.
func triggerIn(seconds: Int) -> UNNotificationTrigger {
let currentSecond = Calendar.current.component(.second, from: Date())
var dateComponents = DateComponents()
dateComponents.calendar = Calendar.current
dateComponents.second = (currentSecond + seconds) % 60
return UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
}
Notification request
let content = sampleNotificationContent()
let trigger = triggerIn(seconds: 5)
let uuidString = UUID().uuidString
let request = UNNotificationRequest(identifier: uuidString, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request) { (error) in
if error != nil {
print("Failed to add a notification request: \(String(describing: error))")
}
}
Handle notifications
Following functions are implemented in the sample project AppDelegate.
Background
This is called when your application is in the background (or even if your application is running, see Foreground below).
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler:
#escaping () -> Void) {
guard let action = Note.Action(rawValue: response.actionIdentifier) else {
print("Unknown response action: \(response.actionIdentifier)")
completionHandler()
return
}
let userInfo = response.notification.request.content.userInfo
guard let meetingId = userInfo[Note.UserInfo.meetingId.rawValue] as? String,
let userId = userInfo[Note.UserInfo.userId.rawValue] as? String else {
print("Missing or malformed user info: \(userInfo)")
completionHandler()
return
}
print("Notification response: \(action) meetingId: \(meetingId) userId: \(userId)")
completionHandler()
}
Foreground
This is called when the application is in the foreground. You can handle the notification silently or you can just show it (this is what the code below does).
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler:
#escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .badge, .sound])
}
iOS customization
There's another way how to customize the appearance of notifications, but this is not available on the macOS. You have to use attachments.

watchOS, not receiving remote notifications

I am developing app on WatchOS 6 but I cannot receive remote notification
Here is my registration code for push notifications in ExtensionDelegate I am getting valid device token.
extension ExtensionDelegate {
func setupRemoteNotifications() {

I've added Push notification Entitlement in WatchExtensions
I am sending notification from Push Notification Tester app using valid TeamId, P8 cert, P8 key, bundle Id -> where I am getting success.
I am sending default test notification nothing special
{
"aps": {
"alert": {
"title": "Silver Salmon Creek",
"body": "You are within 5 miles of Silver Salmon Creek."
},
"category": "Notification"
}
}
I have similar code for iOS and there notification are delivered correctly on iPhone.
UPDATE
I've tested a little bit more
And I have application added to my iPhone app
but iPhone app is for iOS 13
and Watch app is for WatchOS 6
So as I understand this WatchOS app can be install as standalone application.
I have checked "Support running without iOS App installation"
So as I understand my server should send this notification to both
Watch device Token and iOS device token. And there APNS/iOS/watchOS take the decision if there is duplicated notification where to deliver this notification i.e. to iPhone / watchOS.
If there is only watchOS app I think it will be delivered to watch Device token
If there is both watch/iOS app then it will send to iOS and then device whether user is using iPhone/Watch in given moment and deliver it to currently used device.
So now if I send notification to iPhone device token with iOS bundle identifier, and have locked iPhone and watch on wrist I am getting notification on my WatchOS and even can look at long notifications with dynamic content.
But when I've uninstall iOS version of application, and send notification with iPhone or watch device token and appropriate bundle id iOS/watchOS then for standalone app I am not getting this notification delivered again.
I encountered a similar issue, be sure your p8 Bundle ID is using the explicit WatchkitApp ID and not the Extension's ID.
Once I dropped the .watchkitextension and uninstalled (the app), reinstalled, reregistered the device, it worked.
I found the issue. It was related with the way Push Notification is send from the server using node-apns. I also have old Push Notification Tester app. 3.0 version of node-apns is required. there is additonal Header field send to APNS server

I am getting FCM push notification in both languages English/Arabic but I want to show it only in Arabic, How to show this?
My Code-
#available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
if let jsonResult = userInfo as? Dictionary<String, AnyObject> {
if let notifyType = jsonResult["type"] as? String {
if notifyType == "8" || notifyType == "18" {
self.pushRedirection(userInfo: userInfo)
}else{
if let league_id = jsonResult["league_id"] as? String {
if let contestUnique_id = jsonResult["contest_unique_id"] as? String {
}
}
}
}
}
completionHandler([.alert,.sound])
}
I am getting this notification in English(Match Reminder). How to set this in Arabic
My notification data is -
[AnyHashable("gcm.notification.type"): 5, AnyHashable("league_id"): 3, AnyHashable("en_msg"): Match Reminder, AnyHashable("gcm.notification.ar_msg"): القوانين, AnyHashable("gcm.notification.en_msg"): Match Reminder, AnyHashable("gcm.notification.league_id"): 3, AnyHashable("contest_unique_id"): KBm8oVuTR, AnyHashable("gcm.message_id"): 0:1528974245362555%6c5fd9d06c5fd9d0, AnyHashable("gcm.notification.contest_unique_id"): KBm8oVuTR, AnyHashable("ar_msg"): القوانين, AnyHashable("google.c.a.e"): 1, AnyHashable("type"): 5, AnyHashable("aps"): {
alert = "Match Reminder";
}, AnyHashable("body"): Match Reminder]
You need to write a notification service extension. That will allow you to modify the notification's payload prior to display.
As the docs say:
A UNNotificationServiceExtension object ... lets you customize the content of a remote notification before it is delivered to the user.
And that is exactly what you are wishing to do.

Mock UNNotificationResponse & UNNotification (and other iOS platform classes with init() marked as unavailable)

I need to mock UNNotificationResponse and UNNotification so that I can test my implementation of:
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Swift.Void)
However I can't usefully subclass these classes because init() is specifically marked as unavailable, resulting in compilation errors like this if I try:
/Path/to/PushClientTests.swift:38:5: Cannot override 'init' which has been marked unavailable
What alternate approaches can be taken here? I look into going down the Protocol Oriented Programming route, however since I do not control the API being called, I can't modify it to take the protocols I'd write.
To do it you do the following.
Get a real example of the object while debugging and save in file system using your simulator.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
let encodedObject = NSKeyedArchiver.archivedData(withRootObject: notification)
let path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] + "/notification.mock"
fileManager.createFile(atPath: path, contents: encodedObject, attributes: nil)
Find the object in your Mac and add the file in the same target as the test class.
Now unarchive in your test.
let path = Bundle(for: type(of: self)).path(forResource: "notification", ofType: "mock")
let data = FileManager.default.contents(atPath: path ?? "")
let notification = NSKeyedUnarchiver.unarchiveObject(with: data ?? Data()) as? UNNotification
I've used the next extension to create UNNotificationResponse and UNNotification instances while implementing unit tests for push notifications on iOS:
extension UNNotificationResponse {
static func testNotificationResponse(with payloadFilename: String) -> UNNotificationResponse {
let parameters = parametersFromFile(payloadFilename) // 1
let request = notificationRequest(with: parameters) // 2
return UNNotificationResponse(coder: TestNotificationCoder(with: request))! // 3
}
}
Loads push notification payload from file
Creates UNNotificationRequest instance with specified parameters in userInfo
Creates UNNotificationResponse instance using NSCoder subclass
Here are the functions I've used above:
extension UNNotificationResponse {
private static func notificationRequest(with parameters: [AnyHashable: Any]) -> UNNotificationRequest {
let notificationContent = UNMutableNotificationContent()
notificationContent.title = "Test Title"
notificationContent.body = "Test Body"
notificationContent.userInfo = parameters
let dateInfo = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: Date())
let trigger = UNCalendarNotificationTrigger(dateMatching: dateInfo, repeats: false)
let notificationRequest = UNNotificationRequest(identifier: "testIdentifier", content: notificationContent, trigger: trigger)
return notificationRequest
}
}
fileprivate class TestNotificationCoder: NSCoder {
private enum FieldKey: String {
case date, request, sourceIdentifier, intentIdentifiers, notification, actionIdentifier, originIdentifier, targetConnectionEndpoint, targetSceneIdentifier
}
private let testIdentifier = "testIdentifier"
private let request: UNNotificationRequest
override var allowsKeyedCoding: Bool { true }
init(with request: UNNotificationRequest) {
self.request = request
}
override func decodeObject(forKey key: String) -> Any? {
let fieldKey = FieldKey(rawValue: key)
switch fieldKey {
case .date:
return Date()
case .request:
return request
case .sourceIdentifier, .actionIdentifier, .originIdentifier:
return testIdentifier
case .notification:
return UNNotification(coder: self)
default:
return nil
}
}
}
Short answer: You can't!
Instead, decompose your implementation of
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Swift.Void)
and test the methods you call from there, instead.
Happy testing :)
It appears you can initialize UNNotificationContent objects. I've chosen to rework my push handling methods to take UNNotificationContent objects instead of UNNotificationResponse/UNNotification.
If the UNNotificationResponse value doesn't matter, and you just want to execute that method of your app delegate, you can accomplish this by creating a mock by subclassing NSKeyedArchiver like this:
class MockCoder: NSKeyedArchiver {
override func decodeObject(forKey key: String) -> Any { "" }
}
You can then call it like this:
let notificationMock = try XCTUnwrap(UNNotificationResponse(coder: MockCoder()))
appDelegate.userNotificationCenter(UNUserNotificationCenter.current(), didReceive: notificationMock) { }
Your app delegate's userNotificationCenter(_:didReceive:withCompletionHandler:) method will now have been called, allowing you to assert to your heart's content (assuming no assertions against the notification itself, at least).
You can use class_createInstance(UNNotification.classForKeyedArchiver() ...)and cast the value as UNNotification
If you want to manipulate its content and date members you can subclass UNNotification and use this same formula «changing class name and cast to your subclass» to create it, then you override those members- which are open- and return whatever you want
