Motivation and Context

Due to changes in App Store Connect API 2.4, beta_tester_metrics for betaTesters in Spaceship are invalid, resulting in Tester status information no longer being available, beta_tester_metrics is empty.

Description

Based on the betaTesters interface (appstoreconnect.apple.com/iris/v1/betaTesters), updated beta_tester.

Testing Steps

user_id = params[:user_id].to_s
user_password = params[:user_password].to_s
ios_app_id = params[:ios_app_id].to_s
team_id = params[:portal_team_id].to_s
itc_team_id = params[:itc_team_id].to_s

client = Spaceship::ConnectAPI::Client.login(user_id, user_password, portal_team_id: team_id, tunes_team_id: itc_team_id)
puts 'ConnectAPI login success🎉'

puts "#{DateTime.now.to_time} Start getting a list of testers, take a cup of tea🍵……"
testers = client.get_beta_testers(filter: { apps: ios_app_id, isDeleted: false },
                                  includes: 'betaTesterMetrics', 
                                  sort: 'betaTesterMetrics.betaTesterState', 
                                  limit: 10)

testers.each do |tester|
  unless tester.respond_to?(:beta_tester_state)
    puts "\n\n~~~~~~~~~~ 🏃Exception skip: illegal BetaTester data ~~~~~~~~~~"
  end

  puts "TesterID：#{tester.id.to_s} state-#{tester.beta_tester_state}"
end

the reason of check error for macOS(Xcode 11.7.0, Xcode 13.0.0) is Xcode 13.0.0 is not supported and Xcode 11.7 is no longer supported in circleci
