title: XCode list of project configurations
body: <p>I'm writing script that build apps with cron task, I can build any app with terminal call like
  <strong>xcodebuild [-project projectname] [-activetarget] [-alltargets] [-target targetname] [-parallelizeTargets] [-activeconfiguration] [-configuration configurationname] [-sdk  | ] [buildaction ...] [setting=value ...] [-default=value ...</strong></p>
  
  <p>I can set '-configuration' value to Release (common for most of apps), but I'm confused when app does not have this configuration (so for example it has AdHoc or Distr, etc)</p>
  
  <p>Is there any opportunity to retrieve list of configuration set for project so I can choose what I need and put it as -configuration value</p>
