Receiving Push Notifications on Swift with AWS Mobile Hub - ios

I am currently developing and iOS app using Swift, which I am new to, and the code generated from AWS Mobile Hub, with AWS SNS to register devices and send notifications.
On my class AWSMobileClient I have the following code:
func didFinishLaunching(_ application: UIApplication, withOptions launchOptions: [AnyHashable: Any]?) -> Bool {
print("didFinishLaunching:")
// Register the sign in provider instances with their unique identifier
AWSSignInProviderFactory.sharedInstance().register(signInProvider: AWSFacebookSignInProvider.sharedInstance(), forKey: AWSFacebookSignInProviderKey)
var didFinishLaunching: Bool = AWSIdentityManager.default().interceptApplication(application, didFinishLaunchingWithOptions: launchOptions)
didFinishLaunching = didFinishLaunching && AWSPushManager(forKey: ServiceKey).interceptApplication(application, didFinishLaunchingWithOptions: launchOptions)
if (!isInitialized) {
AWSIdentityManager.default().resumeSession(completionHandler: { (result: Any?, error: Error?) in
print("Result: \(result) \n Error:\(error)")
}) // If you get an EXC_BAD_ACCESS here in iOS Simulator, then do Simulator -> "Reset Content and Settings..."
// This will clear bad auth tokens stored by other apps with the same bundle ID.
isInitialized = true
}
return didFinishLaunching
}
Which is called normally.
On my AppDelegate, I have the following:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
AWSMobileClient.sharedInstance.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
NotificationCenter.default.post(name: Notification.Name(rawValue: AWSMobileClient.remoteNotificationKey), object: deviceToken)
print("###--- DID REGISTER FOR REMOTE NOTIFICATION ---###")
}
Which is also called.
However, when I try sending a notification using AWS SNS, my function:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("###--- DID RECEIVE REMOTE NOTIFICATION ---###")
AWSMobileClient.sharedInstance.application(application, didReceiveRemoteNotification: userInfo , fetchCompletionHandler: completionHandler)
// This is where you intercept push notifications.
if (application.applicationState == .active) {
UIAlertView.init(title: "Notification Received", message: userInfo.description, delegate: nil, cancelButtonTitle: "OK").show()
}
}
Is never called.
Looking for a solution I read that since iOS 10 there are some chances that need to be made to deal with push notification, but I'm not sure about the correct ways.
How should I implement the code to receive the notifications?

How to configure Pusher Beams SDK with Firebase in App Delegate?

I have the Firebase SDK in my project for the backend and I am using the Beams SDK from Pusher to configure push notifications.
The issue is that, it doesn't seem that my app delegate is configuring the settings I need to send notification with the Beams SDK if I have Firebase. Here is what I mean.
According to the Beams SDK I need to place this code in the didFinishLaunchingWithOptions
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
self.pushNotifications.start(instanceId: "MyInstanceID")
self.pushNotifications.registerForRemoteNotifications()
try? self.pushNotifications.addDeviceInterest(interest: "debug-hello")
// FirebaseApp.configure() . However it ONLY works properly when this is commented out
return true
}
As I showed above, it only configures my notifications properly if I comment out the Firebase configuration. Here is other relevant code in my delegate:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("RECEIVED NOTIFICATION")
self.pushNotifications.handleNotification(userInfo: userInfo)
if Auth.auth().canHandleNotification(userInfo){
completionHandler(.noData)
return
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("Did register for remote notifications")
self.pushNotifications.registerDeviceToken(deviceToken)
Auth.auth().setAPNSToken(deviceToken, type: .prod)
}
How do I properly configure both in my project?
The issue is that Firebase.configure() will break the didRegisterForRemoteNotificationsWithDeviceToken method.
You need to add GoogleUtilitiesAppDelegateProxyEnabled to the info.plist and set it to NO.

iOS push notification using Sinch with Swift

I am using Sinch with Swift (with bridging header) for instant messaging and I don't receive any push notification when a message is received.
I have a Development Certificate in the Sinch Dashboard.
Background modes are disabled.
Push notification work with other way (Pusher)
But when I send a sinch instant message the App Delegate's "didReceiveRemoteNotification" function never gets called.
var sinClient:SINClient?
var push:SINManagedPush?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//Sinch Push Notification
sinClient = Sinch.client(withApplicationKey: "-----", applicationSecret: "------", environmentHost: "sandbox.sinch.com", userId: "----")
sinClient?.setSupportMessaging(true)
sinClient?.enableManagedPushNotifications()
sinClient?.delegate = self
sinClient?.messageClient().delegate = self
sinClient?.start()
sinClient?.startListeningOnActiveConnection()
self.push = Sinch.managedPush(with: SINAPSEnvironment.development)
self.push?.delegate = self
self.push?.setDesiredPushTypeAutomatically()
self.push?.registerUserNotificationSettings()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print("Device Token: \(token)")
self.push?.application(application, didRegisterForRemoteNotificationsWithDeviceToken: deviceToken)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
self.push?.application(application, didReceiveRemoteNotification: userInfo)
}
func managedPush(_ managedPush: SINManagedPush!, didReceiveIncomingPushWithPayload payload: [AnyHashable : Any]!, forType pushType: String!) {
sinClient?.relayRemotePushNotification(payload)
}
Instant Message are received only when I open the app.
Finally I found that the problem was that I used the simulator to send the message

Apple Push Notifications in tvOS

Hi i am a newbie to tvOS. I have an TV application which is registered for APNS.
But while i push a notification i am not able to get the notifications.
i am getting the device token but not the notification.
While i try with the Mobile Devices i am getting the notifications,But not in the tvOS why is it so...?
How can i solve this..?
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
if granted == true
{
print("Allow")
UIApplication.shared.registerForRemoteNotifications()
}
else
{
print("Don't Allow")
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print("DEVICE TOKEN = \(deviceTokenString)")
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print(error)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
print(userInfo)
}
tvOS supports only 2 types of notifications: badges and content-available. So you need to send one of these two types to APNS. Any of these types notification only changes badge number on App Icon. And only the lastest notification will be delivered to your application when you open the app. There is no visual presentation of notification as it was on iOS
How it looks see on presentation from WWDC 2016/Session 206/tvOS, start watching from 21:20
UPDATE:
On tvOS 11 appeared Silent notifications which wakes the application up and allow to refresh content in background
WWDC 2017 watch from 7:50
This is my solution for Notifications in tvOS.
in AppDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// set self (AppDelegate) to handle notification
UNUserNotificationCenter.current().delegate = self
// Request permission from user to send notification
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound], completionHandler: { authorized, error in
if authorized {
DispatchQueue.main.async(execute: {
application.registerForRemoteNotifications()
})
}
})
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
//print(userInfo)
print("Notification Received")
let nc = NotificationCenter.default
nc.post(name: Notification.Name("foo"), object: nil)
}
The first function provide the permission necessary for notification.
And the second function received the notification and send a notification to the current viewcontroller and make the magic happpend.
This is the viewcontroller
//viewload NotificationCenter.default.addObserver(self, selector: #selector(updateTable(_ :)), name: Notification.Name("foo"), object: nil)

didReceiveRemoteNotification not called Swift

For some reason my didReceiveRemoteNotification is never called. I have done the following:
checklist of APNS:
Create AppId allowed with Push Notification
Create SSL certificate with valid certificate and app id
Create Provisioning profile with same certificate and make sure to add device
With Code:
Register app for push notification
Handle didRegisterForRemoteNotificationsWithDeviceToken method
Set targets> Capability> background modes> Remote Notification
Handle didReceiveRemoteNotification
Yet my function does not seem to get called. My code looks like this:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
if (application.respondsToSelector("isRegisteredForRemoteNotifications"))
{
// iOS 8 Notifications
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: (.Badge | .Sound | .Alert), categories: nil));
application.registerForRemoteNotifications()
}
else
{
// iOS < 8 Notifications
application.registerForRemoteNotificationTypes(.Badge | .Sound | .Alert)
}
return true
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for var i = 0; i < deviceToken.length; i++ {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
apnsID = tokenString
println("******apnsID is \(apnsID)")
dToken = deviceToken
println("******dToken is \(dToken)")
NSUserDefaults.standardUserDefaults().setObject(deviceToken, forKey: "deviceToken")
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
println("***********didFailToRegisterForRemoteNotificationsWithError")
println(error)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
println("Getting notification")
var message: NSString = ""
var alert: AnyObject? = userInfo["aps"]
println(userInfo["aps"])
if((alert) != nil){
var alert = UIAlertView()
alert.title = "Title"
alert.message = "Message"
alert.addButtonWithTitle("OK")
alert.show()
}
}
add content_available:true in your request . for iOS payload data.You will get notification in didReceiveRemoteNotification. Now handle it.
As I found out having the same problem myself, in order for didReceiveRemoteNotificationto be called, the incoming notification music carry an "available_content" : true parameter with the notification payload. So in case of you sending the notification in a dictionary form , as was my case in device to device pushes, you just have to add it in the dictionary as you would specify other parameters as you would for sound or badge, also needed if you're using some sort of push service as Postman
Three steps:
Add logic here to handle incoming notification:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
// Add your logic here
completionHandler(.newData)
}
Add Background mode to capabilities in target, and ensure to check 'Remote notifications'
While sending a push notification, add "content_available" : true
This worked for me in iOS 14/Xcode 12.3.

Not receiving Push Notifications from CloudKit Subscriptions

I'm not receiving Push Notifications I expect from CloudKit Subscriptions.
Here's what I've done so far:
Enabled the CloudKit and Remote Notifications capabilities.
Created a 'Test' Record Type using the CloudKit dashboard.
Created a subscription for the appropriate record type (Test), which
I can see in the CloudKit dashboard.
Use a physical device to test, which is signed in to iCloud and
connected to the internet.
Set up the app delegate to receive notifications.
Manually Inserted/Updated/Deleted records via the CloudKit portal.
Unfortunately I never receive any push notifications, ever. The code involved is shown below. Literally, this is the only code in a brand new blank project.
// MARK: - SUBSCRIPTIONS
func subscribeToRecordChangesWithRecordType (recordType:String, database:CKDatabase) {
let predicate = NSPredicate(value: true)
let subscription = CKSubscription(recordType: recordType, predicate: predicate, options: CKSubscriptionOptions.FiresOnRecordCreation|CKSubscriptionOptions.FiresOnRecordDeletion|CKSubscriptionOptions.FiresOnRecordUpdate)
database.saveSubscription(subscription, completionHandler: { (savedSubscription, error) -> Void in
if let _error = error {
NSLog("ERROR saving '%#' subscription %#",recordType, _error)
} else {
NSLog("SUCCESS creating '%#' subscription: %#", recordType, savedSubscription)
}
})
}
func createSubscriptions () {
let privateDB = CKContainer.defaultContainer().privateCloudDatabase
let publicDB = CKContainer.defaultContainer().publicCloudDatabase
// NOTE: create a Record Type called 'Test' in the CloudKit dashboard
self.subscribeToRecordChangesWithRecordType("Test", database: privateDB)
self.subscribeToRecordChangesWithRecordType("Test", database: publicDB)
}
// MARK: - PUSH NOTIFICATIONS
func registerForPushNotifications (application: UIApplication) {
self.createSubscriptions()
let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
NSLog("Registered for Push Notifications with token: %#", deviceToken);
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
NSLog("FAILED to register for Push Notifications. %#", error)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
NSLog("RECEIVED Push Notification")
NSNotificationCenter.defaultCenter().postNotificationName("PushNotificationReceived", object: userInfo)
}
func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
NSLog("RECEIVED LOCAL Push Notification")
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
NSLog("RECEIVED Push Notification with fetchCompletionHandler")
NSNotificationCenter.defaultCenter().postNotificationName("PushNotificationReceived", object: userInfo)
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
self.registerForPushNotifications(application)
return true
}
Thanks in advance for any tips or suggestions. I hope this isn't a bug and that I'm doing something wrong here ... it should 'just work'!
Cheers
Make sure
You have enabled Push Notification besides CloudKit (and Background Mode if needed) in App's Capabilities tab. And if needed, find the push certificates (one for Dev, one for production) from Developer Portal, download them and install them (by double clicking on them);
You're testing the app on a device. Apple does not push to the simulator.
