Is there Camera Device Simulation in iOS Simulators?

There is one known workaround which could be useful sometimes: https://github.com/YuigaWada/iCimulator

But it does not work with 3-rd party libs like WebRTC though...

According to Apple documentation, using camera with Simulator is not supported:

The following hardware is not supported in Simulator:

• Ambient light sensor

• Audio input, except for using Siri by choosing Hardware > Siri.

• Barometer

• Bluetooth

• Camera

• Motion support (accelerometer and gyroscope)

• Proximity sensor
