I have set IOS_FIREBASE_MESSAGING_VERSION => 7.0.0 "cordova-plugin-fcm-with-dependecy-updated": { "FCM_VERSION": "19.0.0", "GRADLE_TOOLS_VERSION": "3.5.3", "GOOGLE_SERVICES_VERSION": "4.3.3", "SUPPORT_LIBRARY_VERSION": "28.0.0", "ANDROID_DEFAULT_NOTIFICATION_ICON": "@mipmap/ic_launcher", "IOS_FIREBASE_MESSAGING_VERSION":"7.0.0" }

Answer 1

Goto: project/platforms/ios/Hawks Out/Plugins/cordova-plugin-fcm-with-dependecy-updated/AppDelegate+FCMPlugin.m file Line number 190 or 191 this:

(void)messaging:(nonnull FIRMessaging *)messaging didReceiveRegistrationToken:(nonnull NSString *)deviceToken {

Change line into this:

(void)messaging:(nonnull FIRMessaging *)messaging didReceiveRegistrationToken:(NSString * _Nullable)deviceToken {
