🐛 [cloud_firestore] Unknown app crash: FIRESTORE INTERNAL ASSERTION FAILED: value.has_value()

[JoshRice1]

Bug report

Describe the bug
Not able to consistently reproduce but on iOS we have uses that are in crash loops with the following error.:

Fatal Exception: NSInternalInconsistencyException
FIRESTORE INTERNAL ASSERTION FAILED: value.has_value()

Note:
This issue has just come to light. We have been using this for 2+ years without an occurrence of this and wasn't until the last two updates that the issue started.

Steps to reproduce

Steps to reproduce the behavior:

Unclear as I haven't found to root cause due to the vagueness of the error.

Expected behavior

App does not crash and returns an error message that we can process

Sample project

N/A

Hello,
Thanks for your report, it's caused by a bug in the underlying SDK
The new version 9.4.0 of the iOS SDK is planned around August 2 so we will be able to fix it then.

[JoshRice1]

So any word on when 9.4.0 will be available? If I remove the precompiled library stuff from my podfile and do a build will it pull master for the SDK and build with the fix in it?

Sorry but this is affecting quite a few of our users so we want to try to resolve it ASAP.

[akospwc]

Adding $FirebaseSDKVersion = '9.4.0' to the top of my Podfile did the trick for me. Waiting for the results from users/crashlytics now.

[subhash279]

I am having the same issue. May I pls know when 9.4.0 will be available?

[akospwc]

After adding $FirebaseSDKVersion = '9.4.0' to the top of my Podfile, the crash does not occur anymore.

[akospwc]

@Lyokone Firebase-iOS-SDK 9.4.1 is out now: https://firebase.google.com/support/release-notes/ios#9.4.1

[Lyokone]

Hello :)
Currently being done here: #9357
