If we a new enhancement project within which we need to integrate FCM notifications we need to know swizzling is enabled or enabled . How to know swizzling method is enabled or disabled in our project?
Check your info.plist file.
Please check key FirebaseAppDelegateProxyEnabled is set to NO then method swizzling is disabled.
If you have disabled swizzling by setting FirebaseAppDelegateProxyEnabled to NO in your app's Info.plist, you should manually set the APNS token in your application delegate's application:didRegisterForRemoteNotificationsWithDeviceToken: method if you would like to set the type of the APNS token.
