Create a new mac os app in Xcode 14.

Fetch camera list by these code:

NSArray *devicesIOS = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];

then change the architecture to x86_64

snd add com.apple.security.device.camera to entitlements

then this code will cost 4s and UI will be stuck during next half minutes on M1 machine running MacOS 13

This causes a lot of apps stuck at starting like Zoom and Classin

How to solve this?

devicesWithMediaType is deprecated.

Use AVCaptureDeviceDiscoverySession:

let discoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInWideAngleCamera],
                                                        mediaType: .video,
                                                        position: .unspecified)
let devices = discoverySession.devices

and do it in a separate thread, it will take a second or two, not more.
