Fix React Native iOS app build

We updated our app to React Native version 0.73.0.
While Android version builds fine, we have some problems with iOS built.
The error is:

The following build commands failed:
SwiftCompile normal arm64 Compiling\ SessionInitiator.swift,\ SessionsDependencies.swift,\ SessionsProvider.swift /app/mobile/ios/Pods/FirebaseSessions/FirebaseSessions/Sources/SessionInitiator.swift /app/mobile/ios/Pods/FirebaseSessions/FirebaseSessions/Sources/Public/SessionsDependencies.swift /app/mobile/ios/Pods/FirebaseSessions/FirebaseSessions/Sources/Public/SessionsProvider.swift (in target 'FirebaseSessions' from project 'Pods')

SwiftCompile normal arm64 /app/mobile/ios/Pods/FirebaseSessions/FirebaseSessions/Sources/Public/SessionsProvider.swift (in target 'FirebaseSessions' from project 'Pods')
(4 failures)

We use some @react-native-firebase/ libraries, version 18.7.2.
It's important that Hermes stays enabled.

This project is to make our app building iOS version.
