Downloaded the latest Xcode, but it's still using iOS SDK 4.3

Question

when i go to Xcode -> preferences, under the documentation tab, there is the option to check for updates, and it says i'm on 4.3 SDK, but then tells me no updates available... i'm part of the developer program, using Lion OS... and if I try to download the latest Xcode (with SDK 5) from the app store, it tells me it's installed already.

what am i doing wrong here??

Answer 1

The documentation tab of the preferences will allow you to update the documentation.
It won't update Xcode, nor the SDKs.

To do so, you have two options:

1. You downloaded Xcode from the Mac AppStore:
   Simply update from there, an runs the Xcode installer again.

2. You downloaded Xcode from your developer account, on developer.apple.com:
   Log in, and download the latest Xcode installer. Once downloaded, install it.
