A Fabric representative answered this particular question with a no, in Nov 2018, and OOM reporting is nowhere to be found in Crashlytics for iOS as of April 2025. Seems it did exist at one point, but lost in the Fabric -> Firebase transition.
Right now, Firebase Crashlytics doesn't have OOM reporting. It's not planned to be added at this moment.
