Using SinchRTC 4.2.11 for video calling in my iOS project using Swift. I am getting this error '(audio_device_generic.cc:27): BuiltInAGCIsAvailable: Not supported on this platform' while making video call in iOS swift project. I am using SinchRTC 4.2.11.

This indicates that the device has no Automatic Gain Control API available to webRTC on this iOS device.

This is IOS so it does have its own automatic gain control 

In IOS 13+ you can check for this being active.

We strongly advise you to upgrade to the latest version of the iOS SDK as the version you are running is out of support.

Download latest SDK
