title: Why don't I get any compiler warnings in Xcode 4.5?
body: <p>I recently switched to Xcode 4.5 and I no longer receive realtime compiler warnings. I only receive the warnings after building my project. I can literally type in "laskjflskdjf" and get no errors until compile time.</p>
  
  <p>Additionally, after building a project, receiving a warning, and resolving the issue, the yellow or red warning icon is not removed until I build the project again.</p>
  
  <p>Are there build settings that I must manually adjust to correct this?</p>
  
  <p>Thanks!</p>
