We activate our camera extension from host application and wait for user to allow access it in System Settings. Once our host application receives notification camera extension is ready to be used we want to communicate with the extension. When we enumerate AVCaptureDevices or try to find newly added device using CMIOObjectGetPropertyData for property kCMIOHardwarePropertyDevices, our camera extension is not shown. Once we stop and restart host application camera extension is shown as expected, issue only happens once right after activating the extension. Looks like capture devices are not refreshed for host application after camera extension is activated and approved. Is there a way to force system to refresh cameras? Or any other ideas to make extension immediately visible for host application without relaunching it?
