@nativescript/firebase-auth and @nativescript/firebase-ui are incompatible on iOS

Installing both plugins yields the following build errors:

[!] CocoaPods could not find compatible versions for pod "GTMSessionFetcher/Core":
  In snapshot (Podfile.lock):

This may be more of an issue with Google than the plugins, but it's still an issue.

Based on this SO post, I was able to avoid the above error by adding this line to my Podfile:

$FirebaseSDKVersion = '9.6.0'

which down-levels the Firebase SDK. I'm not sure if this is good, but it works for now. My current Podfile now looks like this:

$FirebaseSDKVersion = '9.6.0'

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.build_settings['WRAPPER_EXTENSION'] == 'bundle'
        config.build_settings['DEVELOPMENT_TEAM'] = '< MY TEAM ID>'
      end
    end
  end
end

and the project includes both @nativescript/firebase-auth and @nativescript/firebase-ui, but DAMN it takes a long time to build - like 20 minutes for what otherwise is a Hello World project!

You are the savior! So difficult to even read logs because it fails on the device. Appreciate you posting this

This appears to no longer be an issue with the current version of the @nativescript/firebase-core plugins (3.1.3), so I'm closing this issue.
