How to add GLES2 or GLES3 to the "Graphics APIs" list in Unity?

Hi
I’m trying to build my game to for iOS, when I have Device SDK selected (Player Settings → Other Settings
→ Target SDK) everything builds fine. However when I select Simulator SDK instead, I’m not able to build and I get the following warning:
“In order to build the Xcode project for Simulator make sure that either GLES2 or GLES3 is added to the ‘Graphics APIs’ list because currently Metal is not supported in the Simulator.”


What does this mean? How do I add GLES2 or GLES3 to the “Graphics APIs” list? Is there another way around this, that will allow me to build?
Thanks alot in advance, any answers or thoughts is appreciated

Make Sure that under Player Settings → Other Settings → Auto Graphics API isn’t selected

,I had the same problem:

Player-Settings → Mobile Phone → make sure you don’t have select Auto Graphics API.

Uncheck Auto Graphics API
