I installed the latest iOS update (5.1.1) on my iPhone development. In Xcode, now I get the error "Could not support development." Xcode says I'm updating in the latest SDK. How can i fix this? I am using Xcode 4.3.2 (4E2002).
Go to your organizer and make sure you have a green dot next to the device you are using. If not click "Use for development".
