Ruby script to download Firebase executables when using PodBuilder

download_firebase_executables.rb

#!/usr/bin/env ruby

require 'json'
require 'open-uri'
require 'fileutils'

# Define the path where the executables should be stored
install_path = "./Pods/FirebaseCrashlytics/"

def download_executable(version, executable_name, install_path)
  url = "https://raw.githubusercontent.com/firebase/firebase-ios-sdk/#{version}/Crashlytics/#{executable_name}"
  file_path = "#{install_path}/#{executable_name}"
  
  # Create the install path directory if it doesn't exist
  FileUtils.mkdir_p(install_path)

  File.open(file_path, "wb") do |file|
    URI.open(url, "rb") do |url|
      file.write(url.read)
    end
  end
  
  File.chmod(0755, file_path)
  
  puts "#{executable_name} executable installed to #{install_path}"
end

# Parse the PodBuilder.json file to get the installed version
podbuilder_file = "./PodBuilder/Prebuilt/FirebaseCrashlytics/PodBuilder.json"
podbuilder_json = File.read(podbuilder_file)
podbuilder_data = JSON.parse(podbuilder_json)
entry = podbuilder_data["entry"]
version = entry.scan(/=([\d\.]+)/).flatten.first

# Download the run and upload-symbols executables
download_executable(version, "run", install_path)
download_executable(version, "upload-symbols", install_path)

Podfile.example

post_install do |pi|
  download_executable_script_path = "./download_firebase_executables.rb"
  system("ruby #{download_executable_script_path}")
end

The script is expected to be placed in the project's root directory. If you want to place it somewhere else, you may have to adjust the paths in the script accordingly.
