In one of my previous posts I explained how to create your own MainWindow.xib User Interface Document. I’ve now also created a screencast that guides you through the process. It is actually no longer necessary to use this. I personally think it is easier just to create your application from code, however it is useful to understand how an XCode 3 iOS application is constructed.
Where is MainWindow.xib in XCode 4 on youtube
Any feedback is appreciated in the comments (here, or on youtube).
