firebase-ios-sdk: Memory Leak when calling FirebaseApp.configure

Description

When I was investigating memory leak in our App, after eliminating some of potential codes I found that one of the memory leak issues is actually caused by Firebase iOS SDK and it happens after calling FirebaseApp.configure. I attached the screenshot from memory graph debugger, unfortunately there is no useful information from the backtrace but can confirm all the APMP thing is from Firebase SDK.

Sorry again for the long wait. The fix is now available in the Firebase 10.22.0 release.

Thank you for reporting this issue. We have confirmed the issue and are working on a fix. However, the fix requires a number of changes, so it may not be available soon.

The good news is that the memory leak appears to be a fixed amount, i.e. it won’t increase over time, so users shouldn’t see much of an impact.

@skuske Instruments is showing the leak in a FirebaseAnalytics module in this report versus a FirebaseSessions module in #11027 - so these are almost certainly different leaks.

Can confirm this as well

Xcode 14.3, Firebase SDK 10.6.0

APMP prefixed symbols are from FirebaseAnalytics
