问：Use swift to switch macos microphone (使用swift 切换macos麦克风)

答：You can use Swift programming language to switch the microphone on macOS by utilizing the AVFoundation framework. Here's a sample code snippet that demonstrates how to switch between the input devices on macOS:

import AVFoundation

func switchInputDevice() {
    let session = AVAudioSession.sharedInstance()
    do {
        let inputs = session.availableInputs
        for input in inputs! {
            if input.portType == AVAudioSession.Port.builtInMic {
                try session.setPreferredInput(input)
                break
            }
        }
    } catch {
        print("Error switching input device: \(error)")
    }
}

In this code snippet, we import the AVFoundation framework and define a function named "switchInputDevice". This function gets the shared audio session and retrieves all available input devices. It then iterates through the input devices and checks if the input device is a built-in microphone. If it finds a built-in microphone, it sets it as the preferred input device using the setPreferredInput method of the AVAudioSession class.

You can call this function whenever you want to switch between input devices, such as when you want to switch to a different microphone. Note that this code snippet only demonstrates how to switch to a built-in microphone. If you want to switch to a different type of input device, you will need to modify the code accordingl

                devices = cameras.devices
                
            } else {
                devices = AVCaptureDevice.devices(for: .video)
                
            }

            var cameraModel = [RTMenuModel]()
            
            for device in devices {
                let model = RTMenuModel()
                model.uniqueID = device.uniqueID
                model.deviceId = device.uniqueID
                model.name = device.localizedName
                cameraModel.append(model)
            }
