Hi everyone, I'm new to coding so this might be a really dumb question but I keep getting the following error "expressions are not allow at the top level". I think all the other errors are a flowing of this error, but again; I'm just getting into coding. Can anyone help? For explanation, I'm trying to make an AR app. B https://share.icloud.com/photos/06GfUQktOH8-tZvvNNHYJm7Iw

Hi, Xcode gives me an error when I try to connect automaticallyConfigureSession with arView., it also can't find ARWorldTrackingConfiguration in configuration. Someone an idea of what I'm doing wrong?     override func viewDidAppear( _ animated: Bool){         super.viewDidAppear(animated)         setupARView()     }     // MARK: Setup Methodes     func setupARView() {         arView.automaticallyConfigureSession = false       let configuration = ARWorldTrackingconfiguration()         configuration.planeDetection = [.horizontal, .vertical]         configuration.eviromentTexturing = .automatic       arView.session.run(configuration)     } }
