Hi, this error occurs in the apple store. Xcode is 11.5 and this is the complete crash provided by Firebase. We updated the sdk to version 5.0.24433.0616 and it only worsened or opened the meeting for the other versions of iOS. ---

I made a test application with version 5.0.24433.0616 and just keep an alert waiting, below the source of the example. import UIKit import MobileRTC class ViewController: UIViewController { ``` override func viewDidLoad() { super.viewDidLoad() } @IBAction func pressButton(_ sender: Any) { let context: MobileRTCSDKInitContext = MobileRTCSDKInitContext() context.domain = "####" context.enableLog = true context.locale = .default context.appGroupId = "" let initSuccess = MobileRTC.shared().initialize(context) if (!initSuccess) { return } MobileRTC.shared().getMeetingSettings()?.autoConnectInternetAudio() let authService = MobileRTC.shared().getAuthService() if ((authService) == nil) { return } authService!.delegate = self authService!.clientKey = "####" authService!.clientSecret = "####" authService!.sdkAuth() guard let meetingService = MobileRTC.shared().getMeetingService() else { return } meetingService.delegate = self let param: MobileRTCMeetingJoinParam = MobileRTCMeetingJoinParam() param.meetingNumber = "####" param.password = "####" let returnValue = meetingService.joinMeeting(with: param) guard returnValue == MobileRTCMeetError_Success else { return } } ``` } extension ViewController: MobileRTCAuthDelegate { ``` func onMobileRTCAuthReturn(_ returnValue: MobileRTCAuthError) { print("") } ``` } extension ViewController: MobileRTCMeetingServiceDelegate { ``` func onMeetingError(_ error: MobileRTCMeetError, message: String?) { print("") } ``` } ---

Hi @guedes.rj.1976, Thanks for the reply. Based on the code snippet, it seems like you are trying to join a meeting right after the attempt to perform SDK auth. The SDK authentication is an asychronized action. You must wait until the `onMobileRTCAuthReturn` is triggered and return the auth success status before you would join a meeting. Thanks! ---

Thanks for the answer. In my production application I already do that. And in this example I made the change and it didn’t work. ---

Hi @guedes.rj.1976, Thanks for the reply. I tried to follow the code snippet you have provided above and implement it in our demo app and I did not encounter any issues. Could you provide the steps to reproduce this issue with our demo app? Any chance you could provide an SDK log for us to further investigate? Thanks! ---

Hi, > [@Zoom is not presenting meeting over controller](https://devforum.zoom.us/t/zoom-is-not-presenting-meeting-over-controller/7764/23): > > We are seeing this issue as well. We get MobileRTCMeetingState(rawValue: 1) which is connecting, but the UI never appears and the call never connects. Worked fine previously, we have updated to the latest SDK. Several other people are having this same problem at the link above ---
