Instance Property

isConnected

Indicates whether the device is currently connected.

Declaration

var isConnected: Bool { get }

Discussion

The value of this property indicates whether the device represented by the receiver is connected and available for use as a capture device. When the value of this property becomes false for a given instance, however, it will not become true again. If the same physical device again becomes available to the system, it will be represented using a new instance of AVCaptureDevice.

You can observe changes to the value of this property using Key-value observing.
