Use Firebase in PushNotifications.swift

[trytuna]

I am playing around with Firebase PushNotifications and stubled upon the unimplemented createChannel() method. I want to address that by using the Firebase framework.

But I am having trouble importing FirebaseMessaging in PushNotifications.swift. It says No such module 'FirebaseMessaging'. Unfortunately I am not an expert of the Xcode build tools. Could someone kindly guide me through that?

You can't modify PushNotifications.swift because that's Capacitor code.

Unless you want to work in your own fork of Capacitor with a Firebase dependency, in that case you can do as this PR did
#2738

That helps. Thanks!
