Type Method

default(for:)

Returns the default device used to capture data of a given media type.

Declaration

class func `default`(for mediaType: AVMediaType) -> AVCaptureDevice?

Parameters

mediaType

A media type identifier.

For possible values, see AVFoundation Constants.

Return Value

The default device used to capture data of the type indicated by mediaType.

Discussion

When you use this method to request a camera (using the video media type), the returned device is always of the builtInWideAngleCamera device type. To request other device types, use the default(_:for:position:) method instead.
