property not found on object type - objective-c

Question

I have a class that looks like the following.
#import <Foundation/Foundation.h>
#interface JAMToDoItem : NSObject
#property(nonatomic,strong) NSString *itemName;
#property BOOL * completed;
#property (readonly) NSDate * CreactionDate;
//-(void)MarkAsCompleted:(BOOL)IsComplete onDate:(NSDate*)date;
#end
JAMToDoItem.m file
//
// JAMToDoItem.m
// ToDoList
//
// Created by juanabreu on 2/15/14.

//
#import "JAMToDoItem.h"
#interface JAMToDoItem()
//#property NSDate *completionDate;
#end
#implementation JAMToDoItem
#end
i then try to access the propertys in this class like the following and im getting an error
//
// JAMToDoList.m
// ToDoList
//

// Copyright (c) 2014 juanabreu. All rights reserved.

#import "JAMToDoList.h"
#import "JAMToDoItem.h"
#interface JAMToDoList ()
#property NSMutableArray *toDoItems;
//#property(nonatomic,strong) NSString *itemName;
#end
#implementation JAMToDoList
//#synthesize itemName;

{
}

return self;

// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
-(void)LoadInitialData{
JAMToDoItem *TheItem = [[JAMToDoItem alloc]init];
TheItem.itemName =#"Buy Milk";
}

}
*/
#end
Note: LoadInitialData is being implemented on a another class and im trying to instatiate JAMToDoItem property. I'm basically following the tutorial written by APPLE located Here. At the top of my todolist class i do have the #import "JAMToDoItem.h" which is the class the contains the propertys im trying to set, and where im getting the error.
so the error i end up with
Property 'itemName' not found on object of type 'JAMToDoItem *'
What I'm I missing?

UPD:
The reason is that there is other JAMToDoItem.h file with
//
// JAMToDoItem.h
// ToDoList
//
// Created by juanabreu on 2/15/14.
// Copyright (c) 2014 juanabreu. All rights reserved.
//
#import <UIKit/UIKit.h>
#interface JAMToDoItem : UIViewController
#end
You can find it by Command+left click on
#import "JAMToDoItem.h"
It is located ToDoList/ToDoList/JAMToDoItem.h, and that one that you show us located at
ToDoList/JAMToDoItem.h
Delete references to JAMToDoItem.h and JAMToDoItem.m in you project (select and hit delete)
Delete files ToDoList/ToDoList/JAMToDoItem.h and ToDoList/ToDoList/JAMToDoItem.m
Move files from ToDoList/JAMToDoItem.h and ToDoList/JAMToDoItem.m to ToDoList/ToDoList/JAMToDoItem.h and ToDoList/ToDoList/JAMToDoItem.m
Select them and re-add to the project
