You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: reader.rb
    path of file: ./repos/fastlane/supply/lib/supply
    
    the code of the file until where you have to start completion: module Supply
  class Reader
    def track_version_codes
      track = Supply.config[:track]

      client.begin_edit(package_name: Supply.config[:package_name])
      version_codes = client.track_version_codes(track)
    
    
    def track_version_codes
      track = Supply.config[:track]

      client.begin_edit(package_name: Supply.config[:package_name])
      version_codes = client.track_version_codes(track)
      client.abort_current_edit

      if version_codes.empty?
        UI.important("No version codes found in track '#{track}'")
      else
        UI.success("Found '#{version_codes.join(', ')}' version codes in track '#{track}'")
      end
