Background GPU Access
The entitlement the system requires for a continuous background task to use the GPU.
Discussion
This entitlement works with BGContinuedProcessingTask, which allows your app’s critical work to complete even when the app goes into the background before the task finishes.
To enable GPU use in the task, add this entitlement to your app by adding the Background GPU Access capability to your target in Xcode. For more information, see Adding capabilities to your app.
