The MobileRTC framework really needs to support arm64 for the simulator.

The error:  
`MobileRTC.framework/MobileRTC, building for iOS Simulator-arm64 but attempting to link with file built for iOS Simulator-x86_64`

Without this support, you cannot use the following on an Apple silicon Mac when using the MobileRTC framework. These are serious blockers and Zoom needs to make resolving this a priority for its developers.

- Simulator
- SwiftUI previews
- UI testing

Hi @constantHealthDev,

The meeting SDK for iOS currently does not have support for the arm64 simulator and our engineers have identified the root cause. However, it’s a known issue with the M1 machine and will require Apple side to fix it.

In the meantime, I suggest you to open XCode using Rosetta or you can also deploy your project into a physical device. You can do so by:

1. Opening up your Applications folder,
2. Locate XCode, right click it and select “Get Info”,
3. Under General, select Open using Rosetta.

Thanks!  
Boon Jun

Thanks for your reply @boonjun.tan.

Could you let us know what the root issue is? If more people report the issue it’s more likely to be fixed.
