Hi, I encountered the same problem. I am using AVCapture Device.DiscoverySession retrieves .builtInDualWideCamera,. builtInTripleCamera, and. builtInDualCamera multi camera systems. It is hoped that the camera can switch between cameras based on scaling, lighting, and other factors. However, currently, besides scaling to achieve camera switching, there are other factors that developers can interfere with to achieve automatic camera switching. Is there any other solution to achieve this function?
