# default(_:for:position:)

Returns the default device for the specified device type, media type, and position.

## Declaration

```swift
class func `default`(_ deviceType: AVCaptureDevice.DeviceType, for mediaType: AVMediaType?, position: AVCaptureDevice.Position) -> AVCaptureDevice?
```

## Parameters

- `deviceType`: The type of capture device to request, such as doc://com.apple.avfoundation/documentation/AVFoundation/AVCaptureDevice/DeviceType-swift.struct/builtInWideAngleCamera.
- `mediaType`: The type of media to request capture of, such as doc://com.apple.avfoundation/documentation/AVFoundation/AVMediaType/video or doc://com.apple.avfoundation/documentation/AVFoundation/AVMediaType/audio.
- `position`: The position of capture device to request relative to system hardware (front- or back-facing). Pass doc://com.apple.avfoundation/documentation/AVFoundation/AVCaptureDevice/Position-swift.enum/unspecified to search for devices regardless of position.

Choosing a capture device

## Return Value

Return Value The default system device, or nil if no device currently exists that satisfies the specified criteria.

## Discussion

Discussion Use this method to select the system default capture device for a given scenario. For example, to obtain the dual camera on supported hardware and fall back to the standard wide-angle camera otherwise, call this method twice, as shown below. // The app's default camera. var defaultCamera: AVCaptureDevice? {     // Find the built-in dual camera, if it exists.     if let device = AVCaptureDevice.default(.builtInDualCamera,                                             for: .video,                                             position: .back) {         return device     }          // Find the built-in wide-angle camera, if it exists.     if let device = AVCaptureDevice.default(.builtInWideAngleCamera,                                             for: .video,                                             position: .back) {         return device     }     return nil }
