Tried running with updated versions of the pod dependencies last night (GoogleSignIn v5.0.2 and GoogleUtilities v6.4.0). Started getting different compile errors:

...Plugins/cordova-plugin-googleplus/GooglePlus.m:29:37: No visible @interface for 'GIDSignIn' declares the selector 'handleURL:sourceApplication:annotation:'

[rbrand21]

Noticed I'm two minor versions behind in Xcode. Updating that...

[rbrand21]

Also behind on Mac OS version...updated to 10.15.2...in order to update Xcode

Okay, so an interesting discovery...Removing the plugin cordova-plugin-firebase and keeping cordova-plugin-googleplus results in a successful build. Seems like some sort of competing co-dependency between the two maybe.

[rbrand21]

I think the issue lies with the two plugins (cordova-plugin-firebase and cordova-plugin-googleplus ) managing dependencies differently? As of v8.0.0 of this plugin, CocoaPods is used. However the firebase plugin has not been updated to using CocoaPods and instead specifies dependencies via its plugin.xml.

I downgraded cordova-plugin-googleplus to 7.0.2 which was the latest before the introduction of CocoaPods dep management and things seem to be working now. Going to open an issue on cordova-plugin-firebase to support dep management with CocoaPods.
