Xcode Error Message - Use of unresolved identifier 'NTDeviceScanner'

I entered below code within ViewDidLoad() to begin scanning for device:

let scanner = NTDeviceScanner() // default constructor for Any DeviceType scanner.subscribeFoundDevice { [weak self] (deviceInfo) in let device = NTDevice(deviceInfo) }

---- Received error message on line 'let scanner = NTDeviceScanner()'-----

Error Message: Use of unresolved identifier 'NTDeviceScanner'

Note: The neurosdk class appears to be importing correctly as the autofill in Xcode will autofill 'NTDevice()'.

Thanks very much Brainbit team for the help!
