Build Xcode Framework using xcodebuild

Question

I'm working with an iOS project that produces a Framework directory at the root of the project when I execute Product -> Build For -> Running in Xcode. I need to be able to automate this process on the command line presumably using xcodebuild. However, I can't seem to determine the correct set of parameters to make this happen. Any insight into how to run this same scenario without the GUI? Do I have to look at using lipo?

This is the generic script I created. It creates a framework with combined device and simulator binaries.

#!/bin/bash

while getopts s:w: flag
do
    case "${flag}" in
        s) scheme=${OPTARG};;
        w) workspace="-workspace ${OPTARG}.xcworkspace";;
    esac
done

if [ -z "$scheme" ]
then
      echo "$(basename $BASH_SOURCE) -- build XCFramework"
      echo ""
      echo "$(basename $BASH_SOURCE) -s scheme-name [ -w workspace0-name ]"
      echo ""
      echo "Run this script from the top-level directory of your framework."
      echo "The build result will be here: archives/<scheme-name>.xcframework"
      exit
fi

rm -rf archives/$scheme.xcframework
