The OpenGL ES version support is decided by the device hardware processors, (PowerVR SGX graphics processors). Most older devices support OpenGL ES 2.0 as documented here: https://developer.apple.com/library/archive/documentation/OpenGLES/Conceptual/OpenGLESHardwarePlatformGuide_iOS/OpenGLESPlatforms/OpenGLESPlatforms.html OpenGL ES 2.0 is the baseline profile for iOS devices while support for OpenGL ES 3.0 was added in iOS 7 and later. Devices supporting OpenGL ES 3.0 is listed here (plus the newer devices than listed, Apple doesn't update the list for every new device): https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/HardwareGPUInformation/HardwareGPUInformation.html#//apple_ref/doc/uid/TP40013599-CH106-SW1
When the device is attached to the debugger console in Xcode it is more convenient to get the logs in the console than in a log file.

More nice features was enabled for OpenGL ES 3.0 (commited in 2555629)
Many of the newer iOS devices supports OpenGL ES 3.0. Fallback to OpenGL ES 2.0 if not available.
This also enables more shaders in the iOS port which was requested by users.
Also, log to console when debugger is attached.
