ARWorldTrackingConfiguration() worked for me.
However the app failed to run on my device because of some other error.

Replace the line:

fileprivate lazy var sessionConfiguration = ARWorldTrackingSessionConfiguration()

with:

fileprivate lazy var sessionConfiguration = ARWorldTrackingConfiguration()
