iOS app using Firebase + Unity as Library module using arcore crash

[lucarocchi]

I have my iOS MyApp , using Firebase, and I have to integrate a "Unity as library" module, based on ARCore Geospatial

I have built it trying a lot of different strategies , but no matter what I did , at runtime it log a lot of Firebase conflict and then crash as for the log extract below

The Unity iOS exported app run smooth when run as alone

If I remove Firebase from MyApp everything also run fine

At runtime it logs many error like this :
objc[8956]: Class FIRInstallationsErrorUtil is implemented in both /private/var/containers/Bundle/Application/EE0FB4F1-DFB7-4A15-8781-DE1336275BEA/Loquis.app/Frameworks/UnityFramework.framework/UnityFramework (0x10bcbd960) and /private/var/containers/Bundle/Application/EE0FB4F1-DFB7-4A15-8781-DE1336275BEA/Loquis.app/Loquis (0x101cd0c38). One of the two will be used. Which one is undefined.

then ...

10.19.1 - [FirebaseCore][I-COR000003] The default Firebase app has not yet been configured. Add FirebaseApp.configure() to your application initialization. This can be done in in the App Delegate's application(_:didFinishLaunchingWithOptions:)(or the@main` struct's initializer in SwiftUI).

and finally it crash with this
