Hi 3moeslam,

Thanks for using Zoom SDK and for the post. Are you using UIScene? Did you successfully initialized the SDK? And are you using the network to pass the SDK authentication and then disconnect from the network when trying to join a meeting/webinar? Because normally if you do not have network, you will receive an error in SDK authentication.


Everything working fine, until SDK need to show popup, you use UIAlertView which deprecated from iOS9, so the fix of this issue is to use UIAlertController instead of UIAlertView

Hello @3moeslam @Carson_Chen,

Facing same issue. Is there any work around?


Would you mind providing a .crash file so that we could further investigate this issue?


Hi @Carson_Chen this is crash log in xcode

When can we expect a bug fix?

Hi iOS-Dev-Work,

Thanks for the info. What is the SDK version that you are getting this crash? Is it 4.6.15805.0403 as well?


Hi tmiskiew,

Even though Apple has deprecated the UIAlertView, but it won’t directly cause crashes, so there might be some other issues that are causing this. We are still investigating this issue, once we are able to identify the root cause, we will fix it as soon as possible.

If you are facing this crashing issue, could you provide the .crash file and the SDK version so that we could further investigate?


Hi @Carson_Chen, We removed UIScene from project and it didn’t crash then.

Glad to hear that it is working now. Happy Zooming!
