The preprocessor guard is meant to void the @available condition.

Also something appears not yet to achieve what you want, as on MacOS 13.4 I still get the deprication warning:

libavdevice/avfoundation.m:776:29: warning: 'devicesWithMediaType:' is deprecated: first deprecated in macOS 10.15 - Use AVCaptureDeviceDiscoverySession instead. [-Wdeprecated-declarations]
     return [AVCaptureDevice devicesWithMediaType:mediaType];
