I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Someone forgot to update the dependencies in the release of Firebase Installations.

Easy fix for now:

Add a new FirebaseInstallationFixDependencies.xml to one of your Editor folders.
This will then bump up the version from 1.7.0 to 7.0.0 (or whatever you need).

<dependencies>
  <iosPods>
    <iosPod name="FirebaseInstallations" version="7.0.0" minTargetSdk="8.0">
    </iosPod>
  </iosPods>
</dependencies>

This is a build issue that could have been prevented via a CI/CD build test before releasing new versions that obsolete an older API.

Another stopgap fix would be to change the generated podfile line from

pod 'FirebaseInstallations', '1.7.0'

to

pod 'FirebaseInstallations', '7.0.0'

We have a proper fix for this on the way in an upcoming release.

@alexames : FYI I also see this in 7.0.2.
