After doing a project level find the lower pane displays the text: “No Editor” and nothing else. This just started happening a couple of days ago. I had updated to the latest iPhone Xcode build, this may have had something to do with it.
I just deleted the Developer directory and did a re-install of Xcode 3.2.1. that did not help.
How an I get this to work again?
Xcode preferences were corrupt. ~/Library/Preferences/com.apple.Xcode.plist
Restored from TimeMachine and all is fine.
I suspect that the latest Xcode beta form the iPhone portal may have aused the corruption.
