Error saying the viewController does not exist.iOS Xcode

In my app, It is showing some error like :

 "unknown type name 'purchasedViewController'; DId you mean 'UIPageViewController'?

But actually there is a VC named purchasedViewController and i have imported it in the current VC.

But when i create an object of purchasedViewController in the current VC like:

@property(strong, nonatomic) purchasedViewController *purchasedController;

im getting an error message saying :

"unknown type name 'purchasedViewController'; DId you mean 'UIPageViewController'?

Why is it happening?Any idea?

**************EDIT************** This is my ".h" file

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>
#import "PurchasedViewController.h"

@interface MainScreenViewController : UIViewController
- (IBAction)purchaseItemAction:(id)sender;
@property (strong, nonatomic) IBOutlet UILabel *Label;

@property(strong,nonatomic) PurchasedViewController *purchaseController;

-(void)Purchased;

@end

You might have a problem if somehow headers are importing each other. To avoid that, change the import in your header to look like this:

//MainScreenViewController.h

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>
@class PurchasedViewController;

@interface MainScreenViewController : UIViewController
...

This will tell the header that the class exist but not actually importing it.

Then, in the implementation (.m) file of MainScreenViewController you can actually call the import:

//MainScreenViewController.m

#import "PurchasedViewController.h"
...

Try to give Forward declaration like 

  @class purchasedViewController;
  @interface MainScreenViewController : UIViewController


  @end

I think it works for you
