Remote notification tap not handled when app is killed

I’m running into an issue with remote push notifications on iOS.

When the app is in background or inactive, tapping a notification correctly triggers:

userNotificationCenter(_:didReceive:withCompletionHandler:)

…but when the app is terminated (killed), tapping the notification launches the app, yet no delegate method is called, and my tracking event never gets sent.

I’m using:

SwiftUI @main App

@UIApplicationDelegateAdaptor for the AppDelegate

UNUserNotificationCenter delegate set manually

FirebaseAppDelegateProxy disabled

No SceneDelegate

I’ve tried:

Checking launchOptions?\[.remoteNotification\] (not fired on iOS 15+)

Adding application(\_:continue:restorationHandler:)

Preventing banners during launch (suggestion by chatGPT but made no difference)

Foreground + background tap handling works perfectly — only killed → tap → launch fails to deliver the payload. hell i can't even see logging for that flow.

Some code i have:

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions:[UIApplication.LaunchOptionsKey : Any]? ) -> Bool { UNUserNotificationCenter.current().delegate = self return true } func userNotificationCenter( _ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void ) { handleNotificationTap(response.notification.request.content.userInfo) completionHandler() } public func handleNotificationTap(_ userInfo: [AnyHashable : Any]) { let id = userInfo["notification_id"] let notificationId = (id as? Int).map(String.init) ?? (id as? String) if let finalId = notificationId { Analytics.track("notification_opened", parameters: ["notification_id": finalId]) } else { Analytics.track( "notificationTappedWithoutID", parameters: ["payload": userInfo] ) } }

As you can see there should always be some event send, but currently i receive none. i also tried didReceiveRemoteNotification but that didn't work either.

Any help would be appreciated. been looking in to this for a few nights now.
