Check that the project actually is compiled properly.
I did a silly mistake the first time, by not typing semicolon after the declarations in MyDocumnent.h . Here is the correct syntax of MyDocumnet.h:

// MyDocument.h

#import <Cocoa/Cocoa.h>

@interface MyDocument : NSDocument
id IBOutlet textView;
NSData *fileData;

The author should make this part of the article clearer, but it will also show up as an error in ProjectBuilder.
