After I installed latest beta version(beta 4) of Xcode10, I can no longer start the shader debugger to debug my vertex/fragment metal shaders running on my mobile device.
It was OK when using Xcode 10 beta 3, but now, the "debug" icon is always disabled. When I hover my mouse over the button, it says "Shader Debugger is not supported. This hardware does not support the Shader Debugger".
By the way, my macos version is Mojave beta 4, and my mobile device is iPhone 6, system version iOS 12.0 beta 4. All relating softwares are of the latest beta version for the moment.
Can anyone explain to me why upgrading to Xcode 10 beta 4 breaks shader debugging on iOS devices?
