A script for showing the derived data folder for an Xcode workspace. Intended to be invoked from a custom behaviour

ShowDerivedData.rb

#!/usr/bin/env ruby

#This script currently only works if you have your derived data in the default location

#First look for a project path as our workspace
xcodeWorkspacePath = ENV['XcodeProjectPath']
if xcodeWorkspacePath
  workspaceName = /([\w\s]+).xcodeproj/.match(xcodeWorkspacePath)[1]
#If we don't have a project we have a workspace, check for that and exit with code 1 if that doesn't exist
else
  xcodeWorkspacePath = ENV['XcodeWorkspacePath'] || exit(1)
  workspaceName = /([\w\s]+).xcworkspace/.match(xcodeWorkspacePath)[1]
end

#Replace spaces with underscores
workspaceName = workspaceName.sub(/ /, "_")

#Loop through through the folders and check their workspace path to see if they match
derived_data = File.expand_path("~/Library/Developer/Xcode/DerivedData")
Dir["#{derived_data}/#{workspaceName}*"].each do |folder|
  info = File.read("#{folder}/info.plist");
  workspacePath = /<key>WorkspacePath<\/key>\s*<string>(.*?)<\/string>/.match(info)[1]
  if workspacePath == xcodeWorkspacePath
    %x[open "#{folder}"]
  end
end
