iOS firebase notification doesnt work in background - swift

Question

Hello this I call a Firebase function and if the app is closed or in Background I get a Pushnotification, but on this Notification are additional Data see JS Script.
my Problem is I want to write these data in the Usersdefault but no method is called?!
and I don't know why. if th app is in foreground anything works fine.
in Plist I added "FirebaseAppDelegateProxyEnabled" = NO
JS Function:
let title = "Test";
let body = "TestBody";
const message = {
notification: { title: title, body: body },
apns: {
payload: {
aps: {
"content_available" : 1,
sound: 'default',
badge: 4,
}
}
},
token: "e0BURkoe0EAq....CIscNukai",
data: {
event: "custom1",
type: "CustomTest",
}
}
Appdelegate.swift
See Block:
if ( userInfo["type"] as! String == "CustomTest" ) {
###########
###########
DO SOMETHING
}

You need to change your notification payload . You need to use below payload for IOS notification.
aps:{
alert:
{
title: "title",
body: "body",
name: "name",
event: "custom1",
type: "CustomTest"
}
}
