node.js child_process spawn ignoring equal signs

Question

I'm trying to launch a cordova command with a target device. I've tested the command and it works but when I try to generate it with my code, it ignores the equal sign and therefore won't run. This code does work just not with the addition of "--target='iPhone-7-Plus"

return new Promise((resolve, reject) => {
  const executable = "ionic";
  const arguments = [
    "cordova",
    buildOnly ? "build" : "run",
    platform,
    "--no-interactive",
    "--verbose",
    "--target='iPhone-7-Plus'"
  ].concat(releaseDev === "release" ? ["--prod", "--release"] : []);
  console.log(executable, arguments.join(" "));
  const child = spawn(executable, arguments, {
    stdio: "inherit"
  });
  child.on("close", () => resolve());
  child.on("error", err => reject(err));
});

What am I doing wrong here? Why would it be ignoring my equal sign only but the rest of the command gets added?

If I run cordova run ios --target='iPhone-7-Plus' the command will execute and launch the 7+ simulator without issues.

When spawning I had to add shell: true in order to use the default shell for my os. The shell that spawn was using would strip special characters.

const child = spawn(executable, arguments, {
  stdio: "inherit",
  shell: true
});
