Installing Xcode with iOS 4.3 device simulator?

I installed Xcode 4.3.1 two days ago. I need to access the iOS 4.3 device simulator, but it is not available in the new Xcode. So I went to Xcode > Preferences > Download (tab) and downloaded the Xcode 4.3.1 developer library and the iOS 5.1 library, hoping I could add the 4.3 simulator.

But, this hasn't worked. So far I haven't got the 4.3 simulator installed on my Xcode. What is the solution for this?

The option to download iOS 4.3 simulator is available from within Xcode. You can find it under Preferences > Downloads. Just click on "Install" and you might have to enter your Apple ID credentials.

If you don't see this option, you could try removing your older versions of Xcode and installing the latest one from the Appstore. My version is 4.3.2.

The iOS Simulator app can be found here if it’s installed correctly:

/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app

Or here:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/iPhone Simulator.app

Try a Spotlight search for “Simulator” to make sure the installation actually failed, before you try anything else.
