Description

This sample demonstrates how to identify geoelements in a scene layer.

How it works

Click on a building in the scene layer to select it. Unselect buildings by clicking away from the buildings.

Steps:

1. Create an AGSArcGISSceneLayer passing in the URL to a scene layer service.
2. Use sceneView.touchDelegate to get the screen tap location screenPoint.
3. Call sceneView.identifyLayer(_:screenPoint:tolerance:returnPopupsOnly:completion:) to identify features in the scene.
4. From the resulting AGSIdentifyLayerResult, get the list of identified AGSGeoElements with result.geoElements.
5. Get the first element in the list, checking that it is a feature, and call sceneLayer.select(feature) to select it
