We updated the Firebase iOS SDK version from 6.32.2 to the latest one: 7.10.0
Libraries used (and it's dependencies):
- Firebase Analytics
- Firebase Crashlytis
- Firebase In App Messaging
- Firebase Messaging
- Firebase Performance
- Firebase Remote Config
The setup has been done manually (based on the provided README.md) and no dependency manager was used. The latest version worked without any issues, but the new one causes a the following crash when enabling "Zombie Objects" in the scheme's diagnostics settings:

Random Xcode console output when trying out the app:
objc[73435]: Class _NSZombie_NSURLRequest is implemented in both ?? (0x7fb7c65124b0) and ?? (0x7fb7c6212760). One of the two will be used. Which one is undefined.

What could be causing this? I didn't create a bug ticket in GitHub, since it seems to be a setup issue.
