Thank you to @Larme for helping. With landscape only in target settings. This will give left or right even when the device is held in the portrait orientation.

if let windowScene = UIApplication.shared.connectedScenes
    .first(where: { $0 is UIWindowScene }) as? UIWindowScene {
    
    switch windowScene.interfaceOrientation {
    case .landscapeLeft:
        print("Landscape Left")
    case .landscapeRight:
        print("Landscape Right")
    }
}
