UNUserNotificationCenter didReceive / willPresent not triggered ios 11 - ios

Question

I have a working application with notifications that appear well. Now I would like to handle some event on notification like when the user tap on the banner.
My iOS Deployment Target is 11.0 and the same for my deployment target.
I implemented everything in my AppDelegate.swift file:
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, RCTBridgeDelegate {
var window: UIWindow?
var didFinishLaunching: Bool = false
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
let bridge = RCTBridge(delegate: self, launchOptions: launchOptions)
let rootView = RCTRootView(bridge: bridge, moduleName: "root", initialProperties: nil)
rootView?.backgroundColor = UIColor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1)
self.window = UIWindow(frame: UIScreen.main.bounds)
let rootViewController = UIViewController()
rootViewController.view = rootView
self.window?.rootViewController = rootViewController
self.window?.makeKeyAndVisible()
didFinishLaunching = true
Fabric.with([Crashlytics.self])
FirebaseApp.configure()
// This block is necessary to ask user authorization to receive notification
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(grant, error) in
if error == nil {
if grant {
print("### permission granted")
application.registerForRemoteNotifications()
} else {
//User didn't grant permission
}
} else {
print("error: ",error)
}
})
} else {
// Fallback on earlier versions
let notificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
self.firstLaunchAction()
self.initTracker()
RNSplashScreen.showSplash("LaunchScreen", inRootView: rootViewController.view)
return true
}
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)")
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("### Failed to register for remote notifications with error: \(error)")
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
if response.actionIdentifier == "like" {
print("### Handle like action identifier")
} else if response.actionIdentifier == "save" {
print("### Handle save action identifier")
} else {
print("### No custom action identifiers chosen")
}
// Make sure completionHandler method is at the bottom of this func
completionHandler()
}
As you can see, I use Firebase to send remote notification so I have a payload in json like this :
return {
notification: {
title,
body
},
data: {
title,
body,
...data
},
android: {
ttl: 3600 * 1000,
notification: {
icon: 'stock_ticker_update',
color: '#002559'
}
},
apns: {
payload: {
aps: {
alert: {
title: 'NITL ACUMEN BI RFS CODA Dev Offshore',
body: 'Send a Message - PN testing group'
},
sound: 'default'
}
}
},
condition
};
Most part of my code is copied from website. But my actual behaviour is that, when I click on the notification banner nothing happen ...
I see the nofication banner so I think there is no problem with my APNs registration. I don't know why didReceive is not trigger on click event.
Do I miss something in my implementation ? My notification payload is wrong ?
Does someone can help me to figure out where is my mistake ? I've read an infinite number of tutorials without results. Some help would be really appreciated thank you :)

To support a background update notification, make sure that the payload’s aps dictionary includes the content-available key with a value of 1.
{
"aps" : {
"content-available" : 1,
"sound" : “default"
....
},
....
}
When a background update notification is delivered to the user’s device, iOS wakes up your app in the background and gives it up to 30 seconds to run. In iOS, the system delivers background update notifications by calling the application: didReceiveRemoteNotification: fetchCompletionHandler: method of your app delegate.
