- iOS 11.0+
A point in the 2D coordinate system of the view.
The types of hit-test result to search for.
A list of results, sorted from nearest to farthest (in distance from the camera).
Hit testing searches for real-world objects or surfaces detected through the AR session's processing of the camera image. A 2D point in the view's coordinate system can refer to any point along a 3D line that starts at the device camera and extends in a direction determined by the device orientation and camera projection. This method searches along that line, returning all objects that intersect it in order of distance from the camera.
