Try Build > Clean > Clean before running and see if that helps.

Sounds like a crash. Check the console log.

That means it's looking for a nib file called MainWindow.xib and not finding it. You need to make sure this file exists in your workspace, or change the initWithNibName call that references it.

Perhaps you should work through a few tutorials and learn a little more about C/Objective-C exceptions and debugging before continuing with this project.

We can't create mainwindow.xib file?

Click to expand...

MainWindow.xib should have come with your application when you created a new project...unless you're working with something from before the beta 7 (I think) release of the SDK.

I'd say just create a new project (window) and then copy and paste all your files back.
