UIColor expected a type after update to xCode 7.3

问题

My project stop to compile after was updated to 7.3 version. For this moment main problem is in header files when I want to return UIColor. xCode tells me Expected a type error. Is there some way to handle with this situation?

Edit: my code (nothing special)

#import <Foundation/Foundation.h>

@interface NSString (Color)

- (UIColor *)rgbColor; //Expected a type
- (UIColor *)hexColor; //Expected a type

@end

回答1:

You should import uikit if you are using UIColor.

回答2:

Use

@class UIColor;

above @interface.

It'll fix the expected a type error.
