Xcode not updating nib files.

Question

I am adding new properties in the controller but they are not appearing in IB. I am putting IBOutlet before the properties but for some reason they are not appearing there, neither IBActions.

I restated xcode, my computer but nothing is changing this.

This problem started when i installed the new version of xcode 3.2.3.

Update: OK i was able to solve the issue by reloading and read the class file in IB. But i still not sure why this is happening? Following thread helped a lot.
