Answer 1

This works perfectly for me

#!/usr/bin/ruby

require 'rubygems'
    begin
        require 'Plist'
        rescue LoadError => e
        puts "You need to install the 'Plist' gem: [sudo] gem install plist"
    exit 1
end

raise "Must be run from Xcode" unless ENV['XCODE_VERSION_ACTUAL']

GIT = "/usr/bin/env git"
PRODUCT_PLIST = File.join(ENV['BUILT_PRODUCTS_DIR'], ENV['INFOPLIST_PATH'])
HASH = `#{GIT} log -1 --pretty=format:%h`
BUNDLE_VERSION = "CFBundleVersion"

if File.file?(PRODUCT_PLIST) and HASH

    # update product plist
    `/usr/bin/plutil -convert xml1 \"#{PRODUCT_PLIST}\"`
    info = Plist::parse_xml(PRODUCT_PLIST)
    if info
        info[BUNDLE_VERSION] = HASH
        info["GCGitCommitHash"] = HASH
        info.save_plist(PRODUCT_PLIST)
    end
    `/usr/bin/plutil -convert binary1 \"#{PRODUCT_PLIST}\"`

    # log
    puts "updated #{BUNDLE_VERSION} to #{HASH}"
    puts "HEAD: #{HASH}"
end
