Latest iOS SDK Crashes Everytime on Xcode 12

Anytime I try to start a meeting using MobileRTCMeetingStartParam4WithoutLoginUser, the app immediately crashes.

Which version?

To Reproduce(If applicable)
Steps to reproduce the behavior:
Using Xcode 12, try to start a meeting using the following:

let params = MobileRTCMeetingStartParam4WithoutLoginUser()
    params.userType = MobileRTCUserType_APIUser
    params.meetingNumber = "\(meetingNumber)"
    params.userName = "Name"
    params.userID = userId
    params.isAppShare = false
    params.zak = zak

The crash occurs on any iOS version.

If applicable, add screenshots to help explain your problem.

Smartphone (please complete the following information):

Additional context
I’m not sure if I’m missing some code while starting the meeting that is required in the new SDK but this issue did not exist on the previous version of the SDK

Hey @dbianchi

Thanks for using the dev forum!

I am seeing this as well. Would you be able to provide a crash log to help us with debugging?
