Crash when integrating with Firebase

[elbelga]

• Xcode version: 12.4
• Firebase SDK version: 7.6.0
• Installation method: `CocoaPods

I integrate Firebase in my app, and when I run the app it crash. It's something related with sqlite but I don't know what's is wrong . If I remove EthereumKit dependency the app not crash.

Steps to reproduce:

Create a blank app with the following dependencies

pod 'Firebase/Crashlytics'
pod 'Firebase/Core'
pod 'EthereumKit.swift'

Add a GoogleService-Info.plist and add call to FirebaseApp.configure() in AppDelegate
Run the app and you receive the following crash

I have also opened an issue to Firebase and we are investigating the problem, any ideas?

I have opened an issue to Firebase, and the problem is a conflict with nanopb.

It looks like EthereumKit.swift/EthereumKit/Libraries/lib/libIncubed.a includes a binary version of pb_encode that is intercepting the version from the nanopb CocoaPod that the GoogleAppMeasurement CocoaPod expect to use.

firebase/firebase-ios-sdk#7522

It's possible to add PB_FIELD_32BIT=1 PB_NO_PACKED_STRUCTS=1 PB_ENABLE_MALLOC=1 to nanopb included in EthereumKit?
