We found that there are crash with similar stack trace produced on other framework, such as Sentry. They fixed the crash by swizzling setState method instead of using KVO to observe network request state.
Hi @mattxw . I have a few questions to clarify.
- What version of Alamofire/AFNetworking are you using in the app?
- What type of network request where this crash is occurring?
- Could you create a simple public repo (sample app) where you can reproduce the issue? (And include the steps)
Thanks.

Thanks for the response, @jek-bao-choo! We are not using Alamofire right now, the link attached are reference to this crash issue that also happened on other framework in the past.
As for the type of network request and how to reproduce, we still don't have it yet since the issue only shows up on Firebase Crashlytics.
