        I am loading 256x256 previews of the last 2048 photos of the photo library into a Metal ArrayTexture of size 256x256x2048.

         

        This works nicely on iPhone, iPad and appleTV, but on Mac Catalyst it throws with a call to a method that doesn't exist in the documentation.

         

        Do you guys know where I might be able to enquire about this issue ?
