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

Hi @nysander, did you experience the crash on the simulator and/or a physical device? Thanks!

[nysander]

It was simulator

I so far have been unable to produce the crash using Xcode 26 and iPhone 16 Pro and iPhone 16e simulators. I have verified that the code path in the issue description is triggered.

[ncooke3]

Could a small project that reproduces the crash be provided?

[nysander]

We just use crashlytics and remote config in our project with nothing fancy or custom. Default configurations for both aligned with examples on docs

[nysander]

Eventually I can share some stacktrace if that can help

Is no one here experiencing this other issue? #14950

Does the fix in https://github.com/firebase/firebase-ios-sdk/issues/14948#issuecomment-2960860573 work for you?

[Marco-Cattai]

We were experiencing the same exact issue and we fixed it

Thanks for confirming, @Marco-Cattai . Going to close this. Please see workaround in https://github.com/firebase/firebase-ios-sdk/issues/14948#issuecomment-2960860573. This appears to be a bug with Apple's latest betas.
