Am seeing this too, app built with Xcode 10.3, again started having moved to 6.11.0.

Occurs after the upgrade of nanopb to 0.3.904

[TomLuna]

Got same crash on 6.5.0 with the following pod configuration, not happened in Debug build.

pod 'Firebase/Core', '6.5.0'
pod 'Firebase/Analytics'
pod 'Fabric'
pod 'Crashlytics'

• Fixed by reverting nanopb to 0.3.901 as @iDevid mentioned earlier.

[AlexSeverinov]

pod 'nanopb', '0.3.901' - fix this issue

[paulb777]

Thanks for the reports. It looks like yesterday's 0.3.9.4 nanopb podspec publish broke something in its interaction with FirebaseAnalytics.

We'll work on a solution today. In the meantime please use @AlexSeverinov suggested workaround.

[670608142]

@AlexSeverinov @iDevid Thanks ~

[paulb777]

I just published nanopb (0.3.9011) which rolls back the nanopb tag to 0.3.9.1. The installed pod exactly matches 0.3.9.1 and pod update will get a functional nanopb version again.

We'll continue to investigate the problem with Analytics and 0.3.9.4

[paulb777]

I'm going to close this now since the crash should now be addressed with a pod update.

We'll follow up internally in b/143285077 on the Analytics integration with nanopb 0.3.9.4
