Xcode Simulator: how to remove older unneeded devices?

Question

I\'m running Xcode 4.3.1 iOS-Simulator which originally only supports iOS 5.1.

I need to test my code with iOS 4.3, so I used Xcode\'s \"Install\" feature to install

Xcode 4.6 will prompt you to reinstall any older versions of the iOS Simulator if you just delete the SDK. To avoid that, you must also delete the Xcode cache. Then you won't be forced to reinstall the older SDK on launch.

To remove the iOS 5.0 simulator, delete these and then restart Xcode:

1. /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/PhoneSimulator5.0.sdk
2. ~/Library/Caches/com.apple.dt.Xcode

For example, after doing a clean install of Xcode, I installed the iOS 5.0 simulator from Xcode preferences. Later, I decided that 5.1 was enough but couldn't remove the 5.0 version. Xcode kept forcing me to reinstall it on launch. After removing both the cache file and the SDK, it no longer asked.
