I am trying to port an existing Open GL ES app to metal using metal convert Shader framework, I have followed all the steps as you specified.
I am running this app on iPad Air 2 which supports metal, but still I am getting this error :
“[mgl-info] OpenGL functionality using Metal cannot be provided because Metal is not supported on this device. OpenGL functionality provided by native OpenGL framework.” .
Can you please help, if I am missing a flag to be set or is there any other issue.
