No storage class may be specified (Objective-c ) error

I keep getting

error: no type or storage class may be specified here before 'interface'

Here's the image:

and the code:

#import <Foundation/Foundation.h>

@interface Utilities : NSObject {

}

+ (NSString *)getDocumentsDirectory;
+ (void)showActivityIndicator;
+ (void)hideActivityIndicator;
+ (void)setUser:(NSString *)userName withPassword:(NSString *)password;
+ (NSString *)getUserName;
+ (NSString *)getPassword;
+ (long long)generateTicketNumber;
+ (BOOL)reachable;
+ (NSString *)printerAddress;
+ (NSInteger)port;
+ (void)setAddress:(NSString*)newAddress andPort:(NSInteger)newPort;
+ (void)showDataActivity;

@end


@开发者_运维百科interface CustomUITextField:UITextField{
    NSInteger rowNumber;
}

@property (nonatomic) NSInteger rowNumber;

@end

I reduced the .m file to just simple:

#import "Utilities.h"

@implementation Utilities

@end

I still get the error. (Ofcourse I get warnings for not implementing methods).

I have been trying to figure out what's wrong for past 2-3 hours. Please help. Thanks.

**UPDATE:**I split up the two classes and all of a sudden, I am gettting "property declaration not found ...." error in a totally different class.

Here's my DataCenter.h

#import <Foundation/Foundation.h>


@interface DataCenter : NSObject {
    BOOL updating;
    NSDictionary *dataDictionary;
}

@property (nonatomic, retain) NSDictionary *dataDictionary;

+ (DataCenter *)sharedInstance;
- (void)update;
- (NSArray *)getSTData;
- (BOOL)saveSTData;
- (NSArray *)getLookUpsData;
- (NSDate *)lastUpdated;

- (NSArray *)pendingData;
- (void)registerNewTicket:(NSDictionary *)ticketInfo;
- (void)savePendingData:(NSArray *)data;

@end

And I am getting "Property declaration not in implementation or interface context"

The contents of the header file will be compiled wherever you include/import this header. Check to see that you aren't importing Utilities.h in some other file where there is an error before the #import.
