wantsHDREnvironmentTextures
A flag that instructs the framework to create environment textures in HDR format.
Declaration
var wantsHDREnvironmentTextures: Bool { get set }Discussion
If you set environmentTexturing to .automatic in iOS 12 or later, ARKit gives you environment textures you cast on your app’s virtual content to create realistic reflections. By default, the framework sets wantsHDREnvironmentTextures to true. When your renderer supports HDR environment textures in iOS 13, it enables your lighting engine to output more colors, with a more realistic result.

Both ARView and ARSCNView support HDR environment textures. For more information, see Adding realistic reflections to an AR experience.
For a Metal app that doesn’t yet support HDR environment textures, you can use the following code to receive LDR environment textures until you’re ready to update your renderer for HDR.
if #available(iOS 13, *) {
configuration.wantsHDREnvironmentTextures = false
}
