Hey folks, I have a legacy game that is running OpenGL ES - and it no longer works on the simulators that are running Apple Silicon, ie iPhone 15 Pro, or the 13" iPads. And yes, i'm also running on Apple Silicon (M1 Max). The apps work fine on the actual devices, but the simulator crashes on any glDrawElements with a stack that looks like the following: I have not yet seen an announcement about this not working but i've seen mention in other apps of stopping to support GL (https://github.com/maplibre/maplibre-native/issues/2351) Can anyone shed some light? I'm obviously going to try to fix it, or find a recent sample app from which to start to see what might be up. Or move to metal, but i hadn't bargained for that level of effort atm ;) Any suggestions appreciated!

We’re experiencing an issue with wrong SceneKit hit testing results in iOS 17.2 compared with iOS 16.1 when using the either Metal or OpenGLES2 engines. Tapping on a 3D model to place a SCNNode // pointInScene: tapped point let hitResults = sceneView.hitTest(pointInScene, options: nil) return hitResults.first { $0.node.name?.compare("node_name") == .orderedSame }

can i use the es3.1 api in code?

Help!!!

Hi, I'm displaying linear gray by CAMetalLayer with the shader below. fragment float4 fragmentShader(VertexOut in [[stage_in]], texture2d<float, access::sample> BGRATexture [[ texture(0) ]]) { float color = in.texCoordinates.x; return float4(float3(color), 1.0); } And my CAMetalLayer has been set to linearSRGB. metalLayer.colorspace = CGColorSpace(name: CGColorSpace.linearSRGB) metalLayer.pixelFormat = .bgra8Unorm Why the display seem add gamma? Apparently the middle gray is 187 but not 128.

I know opengl is marked as deprecated since ios12 but I have an old project using it and I want to update some feature of it then release the update version. So I'm wondering if I can still release an app using opengl to app store currently? (I know it's better to shift to MetalKit but for some reason I want to cut the cost if I can. )

Hello everyone! After some time to think about I proceed with graphics api, I figured opengl will be my first since I'm completely new to graphics programming. As in my last post you may find, I was speaking on moltenvk and might just use metal instead, along with the demos I found using metal. So for now, and I know this is said MANY TIMES, apple deprecated opengl but wish to use it because I'm new to graphics programming and want to develop an app(a rendering engine really) for the iPhone 14 Pro Max and macOS Ventura 13.2(I think this is the latest). So what do you guys think? Can I still use opengl es on the 14 max, along with opengl 4+ on latest macOS even though is deprecated?
