Hi All,

Any Update on the above issue.

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.

This is the log when I attempt to start a meeting. There are a bunch of errors, you can also see that it does attempt to connect but never actually connects.

I went back to v4.6.21666.0428 and it seems to work. Not sure what the issue is in v5.0.24433.0616

Can you help us?
The problem as you already reported is in the v5.0.24433.0616 version of the iOS sdk

Hi everyone,

Thanks for the reply. Regarding the issue you are facing, We are able to identify an issue for the situation you are mentioning. When the setMobileRTCRootController is not configured and the video preview feature has enabled(It is enabled by default), the join meeting process will struggle at presenting the video preview view. We will fix this in the next release.

As an alternative solution, please try to configure the setMobileRTCRootController (https://zoom.github.io/zoom-sdk-ios/interface_mobile_r_t_c.html#a74d0a3110932a0f9506b05d6e235b3ba ) or call disableShowVideoPreviewWhenJoinMeeting(https://zoom.github.io/zoom-sdk-ios/interface_mobile_r_t_c_meeting_settings.html#a85841243faa0e974b243ab093d53be88 ) to disable the video preview, this will work as expected.

Im able to get the meeting started with below code for IOS app, But when i click on leave meeting doesn’t close(whereas minimize meeting works), I’m using iphone 7 with IOS version 13.6, Zoom SDK version is 5.0.24433.0616

        let zoomService = MobileRTC.shared().getMeetingService()
        zoomService?.delegate = self
        let joinParams = MobileRTCMeetingJoinParam()
        joinParams.userName = “name”
        joinParams.meetingNumber = “meetingnum”
        joinParams.password = “pwd”

        if #available(iOS 13.0, *) {
            // 13.0 and above
        if let error = zoomService?.joinMeeting(with: joinParams){
            print("error zoom call:\(error)")

Hi @idcinfo,

Thanks for using Zoom SDK. Please have a try with the solution above and see if that helps.


Can you please copy link here, which one you are referring to, As i said, i am able to open the Zoom meeting window with setMobileRTCRootController change. But not able to close the meeting when i click on Leave Button and also share extension is also not working in IOS 13.6

Please have a try with the solution here, using the disableShowVideoPreviewWhenJoinMeeting:

If the issue persists, please provide an SDK log for further investigation. Thanks!

I added below code along with initially mentioned, Still no changes found, I am able to Join the meeting, But could not leave the meeting and share extension is also not working.

    let settings = MobileRTC.shared().getMeetingSettings()
            settings?.disableShowVideoPreview(whenJoinMeeting: true )

Logs printed , when Joining meeting and When clicked on share. no logs printed when i tried to click on leave button.

Probably at least one of the constraints in the following list is one you don’t want.

Try this:

(1) look at each constraint and try to figure out which you don’t expect;

(2) find the code that added the unwanted constraint or constraints and fix it.


"<NSLayoutConstraint:0x281049770 UIView:0x15fff2ee0.width == - 16 (active)>"


Will attempt to recover by breaking constraint

Hi @idcinfo , I´m facing same issue, leave button not working, were you able to fix it?

Hey @Sergio18,

Thanks for using the dev forum!

Can you provide the following:

  • SDK Version
  • Reproduction steps
  • Device info
  • Xcode Version


Thanks for replying @Michael_Condon

I´m currently using
SDK Version - v5.2.42037.1112
Repro steps -

  let params = MobileRTCMeetingStartParam4WithoutLoginUser()
    guard let userId = zoomData?.userId else { return }
    guard let _ = zoomData?.token else { return }
    guard let tokenZAK = zoomData?.tokenZAK else { return }
    params.userID = userId
    params.userType = .unknown
    params.zak = tokenZAK
    params.meetingNumber = "\(zoomData?.meetingIDZoom ?? 0)"
    params.userName = "\(self.meetingDetail?.sender?.name ?? "") \(self.meetingDetail?.sender?.lastName ?? "")"

    if let service = meetingService, let settings = MobileRTC.shared().getMeetingSettings() {
        service.delegate = self
        settings.meetingInviteHidden = true
        settings.meetingPasswordHidden = true
        settings.meetingShareHidden = true
        service.startMeeting(with: params)

Device info-- iPhone 7 iOS version 14.2 & iPhone 11 iOS version 14.3
Xcode Version - 12.4

Hey @Sergio18,

Can you try changing params.userType = .unknown
params.userType = .APIUser


Hi @Michael_Condon thanks for replying

Unfortunately I keep getting same issue, everything works fine except end/leave button.

I tried both
params.userType = .apiUser
params.userType = .zooUser

Hey @Sergio18,

So you can join a meeting, and the UI presents. But nothing happens when the user presses the leave button?


Hi @Michael_Condon

Correct, when leave button is press nothing happens and also I don´t get any logs on console.

Hey @Sergio18,

Are you using scene delegates in your application?
