We get crashes from production apps to FirebaseCrashlytics. This is the stack trace:

Which version

To Reproduce
I don’t have steps to reproduce, but our flow is as followed:

  1. Get push notification
  2. Show incoming call screen with CallKit
  3. When accepting the call use JoinMeeting API with name and meeting Id


  • Device: iPhone 11 Pro
  • OS: iOS 14
  • Version 14.3.0

Hey @idit.barash,

Thanks for using the dev forum!

I am sorry this is happening, crashes are no fun. It does indeed look to be related to the ZoomSDK.

  1. Does this happen every time your flow is run?
  2. Do you by chance have SDK logs from an instance where the crash happened?


Hi @idit.barash,

Thanks for the post and sorry to hear that you are facing such an issue. Besides what Michael is requesting above, could you also provide the following info:

  1. Is this crash happening when exiting the app?
  2. Could you provide the full .crash file or the crash call stack from other threads?

Looking forward to hearing from you. Thank you.

Thank you so much for replying.

  1. Not at all. It happens once every few days
  2. Sorry, but since the crash happens in production I don’t have any logs.
  3. I have no idea, it happens sometimes in production. This means it happens to an end user and I have no way to know what he\she did.
  4. I don’t actually know how to do that in FirebaseCrashlytics :frowning:

I have the exact same issue. My zoom also crashes every time I log on. I have an IPhone 11 Pro Max

Hey @smahajan,

Thanks for using the dev forum!

Would you be able to share the crash information you are recieving in Xcode?
