Firebase.configure() leaks

[REQUIRED] Step 2: Describe your environment

Launching an app with Firebase added through cocoa pods, and then calling FirebaseApp.configure() causes many leaks.

If I don't call Firebase.configure() I get no leaks. If I call Firebase.configure() but I don't make any other calls to firebase I still get the same leaks.

[REQUIRED] Step 3: Describe the problem

Creat app, add firebase, call FirebaseApp.configure() in didFinishLaunchingWithOptions

@paulsUsername Please be more specific. What steps are you following to see the leaks? With Instruments? What are the leaks that you're seeing?

[paulsUsername]

Sorry, Paul I intended on attaching more detail.

To see the problem, I am calling FirebaseApp.configure() in the didFinishLaunchingWithOptions in the AppDelegate.

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        FirebaseApp.configure()
        
        return true
    }

If I remove that call to FirebaseApp.configure() I get no leaks. I am identifying the leaks through instruments in Leaks. I am running the app through my iPhone X on iOS 12. I am making no other calls to Firebase after calling FirebaseApp.configure(). The leaks I am seeing are:

With FirebaseApp.configure() removed I get:

I have the following Firebase PODs added:

Using Firebase (5.9.0)
Using FirebaseAnalytics (5.2.0)
Using FirebaseAuth (5.0.4)
Using FirebaseAuthInterop (1.0.0)
Using FirebaseCore (5.1.4)
Using FirebaseDatabase (5.0.3)
Using FirebaseInstanceID (3.2.2)
Using FirebaseMessaging (3.1.2)
Using FirebaseStorage (3.0.2)

I'm not able to reproduce by adding those pods to one of the quickstarts.

Are the leaks specific to ios12 and/or iPhone X?

Possibly #1917

I'm not seeing the same (or any) leaks on my iPad on 11.4.1 or my iPhone 7 11.4.1. Still seeing them on iPhone X 12.0.
