#!/bin/bash
# Usage:
# ./build-frontend-desktop-app.sh [--disable | --unset-SLOBS_NO_SIGN | --unset-all | --compile | --reload-zshrc]
# Arguments:
# --unset-SLOBS_NO_SIGN to remove SLOBS_NO_SIGN environment var so you can run codesign
# --unset-all to remove both SLOBS_NO_NOTARIZE & SLOBS_NO_SIGN environment variables
# --disable to bypass codesign completely (even if you have APPLE_SLD_IDENTITY set in your environment)
# --reload-zshrc: reload env vars from .zshrc
# --compile: runs yarn compile in the desktop folder
# Example: ./build-frontend-desktop-app.sh --compile --arch=arm64
