How to send Image with firebase Push Notification using swift 3 - ios

Can any one help me to send notification like this:

Firebase push notifications swift 3

So I'm trying to implement push notifications to my app using Firebase, the problem is that the push comes and I receive this message :
[AnyHashable("id_entity"): 18, AnyHashable("icon"): , AnyHashable("click_action"): offer, AnyHashable("body"): test by almotech, AnyHashable("from"): 1054934643579, AnyHashable("title"): Test Push Notification, AnyHashable("subject"): offer]
But it does not come on the iPhone, nothing shows up not on background neither on foreground, nothing at all. Any help?
Below is the code I've used:

Firebase notifications not showing up IOS but the message shows on console

I have a problem while using Firebase push notifications on IOS devices. I send the message from the firebase console and i get it on the log but it is not showing any notification on the devices ive tried.
I have been searching around for posts with similar problems and i have tried everything i have found but it is still not working.
I created the project on firebase, downloaded the google service info file and placed it on the root of the project, turned notifications on on xcode, set priority of messages on high and did a couple of changes.
I also added both 'Firebase/Core' and 'Firebase/Messaging' to the podfile.
Right now i am using the example that Firebase provides you. This is my code.

The app needs to be in the background in order for it to show.
I had the same problem. Check this question to make sure everything is set up correctly.
I followed this answer and this answer and this answer and this is what got it to work for me.
However, there is simple workaround for this - looks like you have to
set the messaging delegate (Messaging.messaging().delegate = ...)
before FirebaseApp.configure()
Meaning:
// add this first
Messaging.messaging().delegate = self
// add this second
FirebaseApp.configure()
and:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().apnsToken = deviceToken
}
and this
extension AppDelegate : MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Your Firebase FCM Registration Token: \(fcmToken)")
}
}

Swift 3 Firebase Remote Notification not showing on TestFlight

Good day, I have this app here that perfectly shows the notification on device plugged to Xcode but does not work when I try to run it on TestFlight or in the real application which has been already uploaded to the App Store.

Make sure you have uploaded the production APNs certificate in the firebase console. I think you have uploaded just the development APNs certificate hence you are able to get the notification with Xcode.Also for testing purpose use the firebase notification console to send notification, you just need to provide the device token in the console.
Add this code in AppDelegate file
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.sandbox)
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.prod)
}
you need to set APNS token for sandbox and prod.

Firebase Push Notification Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)" using Swift3

I receive the (Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "(null)" error when I close the app (Disconnected from FCM). It appears in the debug, but when the app is running and I send a notification, it just shows in the debug. Can any one help me to solve the problem?

1.If you are using Xcode 8.2 and above.
Enable push notification entitlement in Capabilities. Please refer the attachment:
Please go to your firebase console and then find your project and go to its settings, there check in its cloud messaging tab and upload your .p12 certificate into that.

Swift FCM Data Message not received when App is in background (iOS 10)

I've looked through every post I could find and read the Firebase Documentation again and again but I can't find the mistake. My App receives FCM data-messages when in the foreground so no problem there. But when the App is running in the background no data is received. It doesn't even show once the app is opened.
The message priority is set to "high" and "content-available" is set to true. I should receive a bunch of IDs.
Here's my AppDelegate Code (mostly from the FCM example code):
//
// AppDelegate.swift

I've activated Push-Notifications and Background Modes: 'Remote notifications' in the Info.plist. Ideally I'd like to process the data in the background and send the user a notification, if it concerns them.
The data sent looks like this:
{
"to": "\/topics\/substitutions",
"priority": "high",
"content_available": true,
"data": {
"debug": true,
"new_ids": [
7914,
7915,
7916,
7917,
7918
],
"updated_ids": [
]
}
}
I would be ever so grateful if someone knows the solution to this problem.
You must add notification payload to receive notification in background.
{
"to": "\/topics\/substitutions",
"priority": "high",
"content_available": true,
"data": {
"debug": true,
"new_ids": [
7914,
7915,
7916,
7917,
7918
],
"notification":{
"title":"Sample Title",
"body":"sample body!"
}
"updated_ids": [
]
}
}
