This has happened quite a few times.

- Application working fine.
- Then I chose a wrong delegate for a view Application did not work (expected)
- So I chose the right delegate for the view Application still not work / load (should have worked though)
- Quiting Xcode and returning still doesn't fix it.
- Only thing to do is delete the project and recreate it

Anyone faced the same problem, any clues on how to fix it ?
