Using xcode to run DEMO sdk (zoom-sdk-ios-5.9.1.2191) After logining in Zoon Successfully, we run the following code as below.

MobileRTCMeetingStartParam \* param = nil; MobileRTCMeetingStartParam4LoginlUser \* user = [[MobileRTCMeetingStartParam4LoginlUser alloc] init]; param = user; param[.](https://www.tommypetspain.com/)meetingNumber = kSDKMeetNumber; // if kSDKMeetNumber is empty, it‘s a instant meeting. param.isAppShare = false;

Then got the error 150
