Is it possible to use this library on the iOS simulator for m1 macs? Installing this library works fine using `pod install`, but trying to build the app in xcode shows errors like:

```auto
.../react-native-webrtc/ios/RCTWebRTC/WebRTCModule.h:15:9: 'WebRTC/RTCMediaStream.h' file not found

```

Building for a physical iOS device works fine.

If this is not supported currently, is it possible to add support?

Thanks in advance!

Hey,

I use the library on m1 mac.

Can you confirm that you are building by turning the rosetta on? (Xcode → Open using Rosetta)

Second, remove pods, podfile.lock and then do pod `arch -x86_64 pod install`

let me know if this doesn’t work

Hey thank you Rohit! I was able to get it working using Rosetta. 🙂

Is there a way to get this working natively on m1 / would it be possible to add support?
