Tells the delegate when a session is opened on a device.

[`device(_:didCloseSessionWithError:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/device(_:didCloseSessionWithError:))

Tells the delegate when a session is closed on a device.

[`didRemove(_:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/didRemove(_:))

Tells the delegate that a device has been removed.

[`deviceDidBecomeReady(_:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/deviceDidBecomeReady(_:))

Tells the delegate when the device is ready to receive requests.

[`device(_:didReceiveStatusInformation:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/device(_:didReceiveStatusInformation:))

Tells the delegate when status information is received from a device.

[`device(_:didEncounterError:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/device(_:didEncounterError:))

Tells the delegate when a device encounters an error.

[`device(_:didEjectWithError:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/device(_:didEjectWithError:))

Tells the delegate when the ejection is complete.

### Responding to Device Changes

[`deviceDidChangeName(_:)`](/documentation/ImageCaptureCore/ICDeviceDelegate/deviceDidChangeName(_:))
