macOS AppDelegate.m not automatically created?

I am new to xcode and mac programming, and am using "Cocoa Programming - A quick start guide for developers" from the pragmatic programmers as a guide.

If I understand correctly, when i create a new cocoa application, the AppDelegate.m and .h should be automatically created, as they are part of the template.

This is not happening for me, and I was wondering how to have them created when I create a new cocoa app.

Thanks!

Im using version 3.2.3 of Xcode, on Mac OS 10.6.4
I have also noticed that the cocoa application is created with a MainMenu.nib, although shouldn't this be a .xib?

Here is a screenshot of my Xcode

I just tried uninstalling Xcode, with this:

sudo /Developer/Library/uninstall-devtools –mode=all

Then I restarted, and reinstalled, and I am still having the exact same problem..

Any Ideas?

OK, I have managed to fix it!

I uninstalled Xcode again, the same way I had done in the last post.
I then removed all files from the Developer folder, and reinstalled.
When I started a new program in Xcode, the AppDelegate files were there, and the MainMenu file was a .xib, instead of a .nib!
