I have this problem. I'm receiving a notification from CloudKit using application:didReceiveRemoteNotification in AppDelegate. I'm able to receive the recordId, fetch it, and save it successfully. The problem is, the scene doesn't refresh.
final class UserData: ObservableObject {
#Published var items: [Item] = []
func saveFetchedItem(recordId: CKRecord.ID, reason: CKQueryNotification.Reason) {
fetchAndSaveRemoteDataFromCloudKit(recordId: recordId, reason: reason, userData: self)
}
}
in AppDelegate:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
let notification: CKNotification = CKNotification(fromRemoteNotificationDictionary: userInfo)!
if notification.notificationType == .query {
let queryNotification = notification as! CKQueryNotification
let recordId = queryNotification.recordID
let reason: CKQueryNotification.Reason = queryNotification.queryNotificationReason
/// reasons:
/// .recordCreated, .recordUpdated, .recordDeleted
UserData().saveFetchedItem(recordId: recordId!, reason: reason)
}
completionHandler(.newData)
}
In fetchAndSaveRemoteDataFromCloudKit, I'm passing the UserData in order to save the item received and it works. The problem is, I show the items on a List and the list doesn't refresh, even when I print the userData.items and the new item is there.
Is there a connection between AppDelegate and SceneDelegate in order to refresh the scene/window?

I am trying to implement phone auth in SwiftUI using Firebase. I keep getting the following error in the console:
If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method.
I have not disabled swizzling from what I know and I have tried different things.
I set-up my firebase project correctly, anyone else facing the same problem?
I looked up in the documentation and I found a part about this:
func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
// This notification is not auth related, developer should handle it.
}
But I don't know where to put it or how to declare it.
Tried doing the following but nothing changes:
import SwiftUI
import Firebase
import GoogleMaps
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
// This notification is not auth related, developer should handle it.
}
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
for urlContext in URLContexts {
let url = urlContext.url
Auth.auth().canHandle(url)
}
// URL not auth related, developer should handle it.
}
}
#main
struct partidulverdeApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
init() {
FirebaseApp.configure()
GMSServices.provideAPIKey("AIzaSyAaze5cpEcJUgw2WFgLhlTWYr9ZP4fyDNk")
}
var body: some Scene {
WindowGroup {
MainView()
.onOpenURL(perform: { url in
Auth.auth().canHandle(url)
})
}
}
}
Hi I'm using XCode version: 10.1 (10B61) and iPhone SE with iOS version: 12.0.1 (16A404), I installed properly all configuration as documentation explained, I uploaded the Auth .p8 certificate and the p.12 certificates of development and production, but when I try to send a push notification from Firebase console I don't receive any, am I missing something? or I did some wrong? any help, please?

"data" : {

"message" : "{"text":"test" }"
},
"content_available" : true
}
I have tried with Priority high and with Sound option but none works.
Please note that I am not using "notification" key as per client request. i am using only data-message in FCM payload
Please anyone help me to work notification when app is in background without USB connection.
If it works with non-Silent notification then all it means is:
Then payload is not correctly setup. Based on the answers provided to this question I'd just alter the placement of the content_available field into notification(and since you don't want a title body then just don't add title/body) or just into the payload itself until see it working.
I'd also make sure all the correct capabilities in Xcode are set (Enabled Remote notification, Background Fetches in Xcode setup, Enabled Push Notification). As mentioned previously uncheck and recheck all of them again.
And make sure Background App refresh is enabled for your app. This is NOT the same with your notifications. Obviously make sure your notifications are also enabled.:
But if you tried everything and it just doesn't work for 11.3 then it might be a bug. There is this other open question mentioned the same issue of yours. Run the app directly from tapping the app, ie not launching from Xcode and then use the console to see what it's logging related to the silent notification. If you're getting something like this:
default 13:11:47.178186 +0200 dasd DuetActivitySchedulerDaemon Removing a launch request for application <private> by activity <private> default com.apple.duetactivityscheduler
Then likely it's a bug similar to this iOS11 question. But you must open a new radar, because that radar was closed I believe because it was fixed!

Finding pod Version in change log and install pod

and after install pod
letest pod dose't suppot userNotifications Framwork
I try to follow the tutorial to configure my iOS app to receive notifications from Firebase. I'm able to receive the message when the app in foreground, but NOT in background.
Here is the data format I received when the app in foreground mode:
[AnyHashable("notification"): {
body = 80;
e = 1;
}, AnyHashable("from"): 7151xxxxxx8, AnyHashable("collapse_key"): me.caoyang.iOSPushNotification]
I have:
Enabled the Push Notifications, Background Modes (Remote notifications) and Keychain Sharing under Capabilities.
Toggled FirebaseAutomaticScreenReportingEnabled and FirebaseAppDelegateProxyEnabled under Info.plist with YES or NO option many times.
Includes GoogleService-Info.plist into project
and yes, I uploaded the .p12 file.
My questions:
What should be the value of variable gcmMessageIDKey?
What can I do or debug or try to make it work?
