Zig fail to build when including IOKit/IOKitLib.h.
Even the addTranslateC approach does not work.

Zig version: 0.16.0-dev.2535+b5bd49460
macOS version: macOS 26.2

It works with zig v0.15.2

main.zig:

const std = @import("std");
const c = @cImport(@cInclude("IOKit/IOKitLib.h"));

pub fn main() !void {
    const service = c.IOServiceGetMatchingService(c.kIOMasterPortDefault, c.IOServiceNameMatching("pmgr"));
    if (service == c.FALSE) return error.NoMatchingService;
    defer _ = c.IOObjectRelease(service);
}

build.zig:

const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "zig_0_16_iokit_error",
        .root_module = b.createModule(.{
            .root_source_file = b.path("src/main.zig"),
            .target = target,
            .optimize = optimize,
            .imports = &.{},
        }),
    });

    exe.root_module.linkFramework("IOKit", .{ .needed = true });

    b.installArtifact(exe);

    const run_step = b.step("run", "Run the app");

    const run_cmd = b.addRunArtifact(exe);
    run_step.dependOn(&run_cmd.step);

    run_cmd.step.dependOn(b.getInstallStep());

    if (b.args) |args| {
        run_cmd.addArgs(args);
    }

    const exe_tests = b.addTest(.{
        .root_module = exe.root_module,
    });

    const run_exe_tests = b.addRunArtifact(exe_tests);

    const test_step = b.step("test", "Run tests");
    test_step.dependOn(&run_exe_tests.step);
}
