Angle or MetalAngle for iOS

[demiantres]

The Angle website (https://github.com/google/angle) mentions compatibility with iOS (although no build instructions for iOS are given). What is the recommended library for iOS - MetalAngle, or Angle?

So, I have tested MetalAngle in a complex App, right now it performs way worse than just using the "normal" opengl backend. I think google's angle is moving at much higher pace, while this project is maybe not even maintained anymore?

My apologies, I have joined Google since last year so right now it’s complicated to continue working on this independent project since it overlaps with my works in Google.

It’s true that Google’s ANGLE has more performance enhancements & bug fixes than MetalANGLE currently. So I recommend using Google’s ANGLE rather than MetalANGLE as of now. The only downside of Google ANGLE is that it currently doesn’t support IOS out of the box since iOS is low priority there. Furthermore Google’s ANGLE doesn’t implement Objecive-C helper classes like MetalANGLE so you would have to use EGL C API in order to setup a GL context. If someone could create an IOS port (xcode project/build files, etc) for Google’s ANGLE it would be much appreciated.
