Xcode 3.2.2 refusing to open any project folders!?

Question

Hi,

I'm developing on a number of different machines and haven't used my laptop for a while. Today I tried to use for the first time after a couple of months only to find that Xcode steadfastedly refuses to open any .xcodeproj projects!?

I ended up uninstalling the older (I think it was 3.1) Xcode installation and re-installing the latest SDK from scratch, but I keep getting the same error even on newly created projects (e.g. New Project.. crash):

Has anybody else come across this problem? Any caches beyond the ~/Library/Caches/xcodebuild to clean?

Any help would be very much appreciated.

Best regards,

Frank

Answer 1

Right, I figured it out.. apparently there was something offending in the preferences file.

Deleting com.apple.Xcode.plist did the trick.

Answer 2
