Fixes #844

Waiting to merge based on result of Firebase/SpecStaging.

Merging since Firebase nightly tests look good with a similar gtm-session-fetcher change.

Hello and thanks for this fix 🙂

Would it be possible to have this released (and also the change in gtm) soon?

There are downstream packages building on top of this, such as RN Google sign in and maybe Flutter and others that are hitting #844 and having this published would make it easy to use the latest versions.
Thank you 🙂

@vonovak yes, the plan is to release this soon. I don't have a specific date to share because of privacy manifest work that I am responsible for elsewhere. I hope to get to this release in a week or two. Apologies for the delay.

I believe downstream clients can fix their issue -- by using use_frameworks! in their Podfile for example. I do think adding DEFINES_MODULE here is important since it means downstream clients do not need to make a fix on their own.
