*Update: This now doesn’t work on either the iPhone or the Simulator. After I ran a clean build I got the error on the simulator:

Could not load NIB in bundle: 'NSBundle </var/mobile/Applications/572536B3-5E7D-4F2B-8D80-4345412DCF10/Quotes.app> (loaded)' with name 'RootViewController'

I have inspected the MainWindow.xib file and there is no mention of the RootViewController. I renamed this much earlier to CategoryViewController.

Here is my CategoryViewController at the request of @megger: 

#import <UIKit/UIKit.h>
#import "Category.h"
#import "AddSubjectController.h"
#import "SubjectViewController.h"
#import "SBTableAlert.h"

@class SubjectViewController;
@class AddSubjectController;
@class SearchViewController;

@interface CategoryViewController : UITableViewController  <UIAlertViewDelegate, SBTableAlertDelegate, SBTableAlertDataSource> {

    NSMutableArray *categories;
    NSMutableArray *allCategories;
    NSMutableArray *subjects;
    NSMutableArray *allSubjects;
    AddSubjectController *addSubController;
    SubjectViewController *subViewController;
    SearchViewController *svc;
    NSIndexPath* checkedIndexPath;

}

@property (nonatomic, retain) NSMutableArray *categories;
@property (nonatomic, retain) NSMutableArray *allCategories;
@property (nonatomic, retain) Subject *selectedSubject;
@property (nonatomic, retain) Quote *selectedQuote;
@property (nonatomic, retain) NSMutableArray *allSubjects;
@property (nonatomic, retain) NSMutableArray *subjects;
@property (nonatomic,assign) QuoteMapViewController *qmv;
@property (nonatomic,assign) SearchViewController *svc;
@property (nonatomic, assign) NSInteger mySection;
@property (nonatomic, assign) NSInteger myRow;
@property (nonatomic, retain) NSIndexPath* checkedIndexPath;

    Could not load NIB in bundle: 
'NSBundle </var/mobile/Applications/572536B3-5E7D-4F2B-8D80-4345412DCF10/Quotes.app> 
(loaded)' with name 'RootViewController'

    (1) Use a text searcher like BBEdit or EasyFind to search your project folder for “RootViewController”. It’s there somewhere. For example, if you have a class called RootViewController and you instantiate it with alloc-init or in some other way that fails to specify a nib, it will look for a nib called RootViewController.

    (2) What was the last time you did a Clean All on this project? I think it’s time to do one. There may be cruft in your built app, and only a Clean can get it out of there. See my advice here: How to Empty Caches and Clean All Targets Xcode 4
