I want to do logging from a .metal file.
From the specification:

Metal defines the logging functions and types in <metal_logging>. To enable logging, you need to set -fmetal-enable-logging (see section 1.6.9).

I made a simple shader with a log

#include <metal_stdlib>
#include <metal_logging>

using namespace metal;

[[stitchable]] float2 wave(float2 pos, float t) {
    os_log_default.log("SOMELOG");
    pos.y += sin(t * 5 + pos.y / 20) * 5;
    return pos;
}

And getting error “precondition failure: pipeline error: custom_effect-oQAAALAAAABQ9BMA: Encountered unlowered function call to air.os_log”

Metal version 3.2
