When we downloaded Xcode 4.5.1, to test applications in older simulators we installed it from Settings->Downloads->Components Now there is Xcode 4.5.2 available. Again we need to download simulators for that Xcode ? or is there any location where those simulators stored similar to Documentation. In 2nd image below we can see location for documentation but in 1st image selecting simulator doesn't show any location of installation. Any idea ?
