"ObjC declarations may only appear in global scope" Social.framework error

Question

I am trying to import <Social/Social.h> in my project, but when I try to run, I get the error Objective-C declarations may only appear in global scope in the two files SLRequest.h and SLComposeViewController.h. A thing to be mentioned is that the Social.framework remains in Frameworks group in the project navigator even though I've deleted it which I think is the cause of the problem. I tried to remove and re-add it from Link Binary With Libraries, but I had no luck. I tried to use it in another project and it runs with successfully.

Update: #import is above @implementation. This is exactly my code:

#import "flatGreenColor.h" 
#import <MessageUI/MessageUI.h> 
#import <Social/Social.h>

@end 

@interface SettingsController1 () 

@property (nonatomic, strong) NSArray* settingTitles; 
@property (nonatomic, strong) NSArray* settingsElements; 
@property (nonatomic, strong) NSString* boldFontName; 
@property (nonatomic, strong) UIColor* onColor; 
@property (nonatomic, strong) UIColor* offColor; 
@property (nonatomic, strong) UIColor* dividerColor; 

@end

Answer 1

This error was caused as I was adding an @end after #import <Social/Social.h>. I forgot to add it in another header which I was importing to my .m. The answer was provided in the comments by @Tommy
