Ios_getpid() crashes

Meeting SDK iOS

Hi,

After updating to iOS SDK to 4.4.56624.1028 we started getting random crashes.

Crash log:

Here is our code for SDK authentication:

DispatchQueue.main.async {
      authenticateSDK()
 }

func authenticateSDK() {

        let zoomSDK = MobileRTC.shared()
        
        let context : MobileRTCSDKInitContext = MobileRTCSDKInitContext.init()
        context.domain = ZoomAPI.domain
        context.enableLog = true
        context.locale = MobileRTC_ZoomLocale.default
        
        let initializeSuc: Bool = MobileRTC.shared().initialize(context)
        print("initializeSuccessful======>", initializeSuc)
        print("MobileRTC Version:", MobileRTC.shared().mobileRTCVersion()!)
        
        guard let authService = zoomSDK.getAuthService() else { return }
        authService.delegate = self
        authService.clientKey = ZoomAPI.appKey
        authService.clientSecret = ZoomAPI.appSecret
        authService.sdkAuth()
    }

Hi @jon.flanders,

Thanks for using Zoom SDK. Could you provide the following information:

  1. Could you provide the full crash log so that we could further analyze it?
  2. Could you provide the steps of how to reproduce this issue? What are the interfaces or the actions that are causing this crash?
  3. What is the iOS device you are using?
  4. Are you getting this crash in debug mode? Could you also provide the output of bt and image list?

Looking forward to hearing from you.

Thanks!
