ios - @import "Unexpected '@' in program"

Question

I updated project to Xcode 5 and enabled modules in build settings. However, I see compiler error Unexpected '@' in program when I use @import.

#ifndef __IPHONE_7_0
#warning "This project uses features only available in iOS SDK 7.0 and later."
#endif

#ifdef __cplusplus
#import <opencv2/opencv.hpp>
#endif

#ifdef __OBJC__
@import SystemConfiguration;
@import UIKit;

Is it anything else that should be done?

From the comment of @hw731 I think you use badly @import :

old syntax to import framework :

#import <UIKit/UIKit.h>

but now, you can use the new syntax :

@import UIKit;

you need to enable theses modules to use the keyword @import (it's enable by default when you create a new project with Xcode 5) :

Have a look here.
