Cordova and Xcode ios how to modify existing podfile post_install config

How can I add post_install configurations to an existing podfile that already has a post_install section? I need to add a line to fix a build clang ld linker error to debug-iphonesimulator myapp.debug.dylib file.

I can't do it manually because using cordova cordova build ios wipes out the manual podfile edits on every build. I am looking at writing a hook script but the examples I see look like it's placing a new/2nd post_install section at the bottom of the podfile which would error out because (from my understanding) the podfile can only have one post_install section.

My current podfile:

# DO NOT MODIFY -- auto-generated by Apache Cordova
source 'https://cdn.cocoapods.org/'
platform :ios, '13.0'
use_frameworks!
target 'myApp' do
    project 'myApp.xcodeproj'
    pod 'FirebaseCore', '11.8.0'
    pod 'FirebaseCoreExtension', '11.8.0'
    pod 'FirebaseAuth', '11.8.1'
    pod 'FirebaseAnalytics', '11.8.0'
    pod 'FirebaseMessaging', '11.8.0'
    pod 'FirebasePerformance', '11.8.0'
    pod 'FirebaseRemoteConfig', '11.8.0'
    pod 'FirebaseInAppMessaging', '11.8.0-beta'
    pod 'FirebaseFirestore', '11.8.0'
    pod 'FirebaseCrashlytics', '11.8.0'
    pod 'FirebaseFunctions', '11.8.0'
    pod 'FirebaseInstallations', '11.8.0'
    pod 'GoogleSignIn', '7.1.0'
    pod 'GoogleTagManager', '8.0.0'
end

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['DEBUG_INFORMATION_FORMAT'] = 'dwarf-with-dsym'
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
            if target.respond_to?(:product_type) and target.product_type == "com.apple.product-type.bundle"
                config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
            end
        end
    end
end

I need to add this one line: config.build_settings['ARCHS[sdk=iphonesimulator*]'] = 'x86_64' directly under the target.build_configurations.each do |config| section.

The script I am evaluating would be placed in the project root/hooks directory and then in my config.xml file a <hook ...> reference to that script:

#!/usr/bin/env node

const fs = require('fs');
const path = require('path');
const { isFile } = require('cordova-common').FileHelpers;

// This hook is designed to be run as an after_prepare hook.
// It will append custom content to the end of the iOS Podfile.
module.exports = function(context) {
  console.log('Running after_prepare hook to modify Podfile...');

  const platformRoot = path.join(context.opts.projectRoot, 'platforms/ios');
  const podfilePath = path.join(platformRoot, 'Podfile');

  if (!isFile(podfilePath)) {
    console.log('Podfile not found, skipping modification.');
    return;
  }

  let podfileContent = fs.readFileSync(podfilePath, 'utf-8');

  // Define your custom Podfile additions here.
  // This example adds a post_install hook to set specific compiler flags.
  const customContent = `
  # Custom post_install hook added by a Cordova hook
  post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
         # NEED TO ADD THIS LINE TO FIX clang ld linker errors for simulators
         config.build_settings['ARCHS[sdk=iphonesimulator*]'] = 'x86_64' 
      end
    end
  end
  `;

  // Append the custom content to the existing Podfile content
  podfileContent += customContent;

  // Write the modified content back to the Podfile
  fs.writeFileSync(podfilePath, podfileContent, 'utf-8');

  console.log('Podfile modified successfully.');
