Help With Xcode Dependencies

I have a Unity application that I've build and already published to the App Store. I'm trying to update the app with Firebase plugins. Now I'm getting a bunch of "Undefined Symbol" errors when trying to archive the application.

I am a beginner with iOS development but I assume this is a simple fix...

That being said, I have tried just about every solution I can understand on stackoverflow, GitHub forums, unity forums, etc., to the point it made things worse and I fell back on a backup build file.

Any help would be much appreciated. Thanks!
