在Swift项目中使用未声明类型

我试图在我的Swift项目中导入这个库.我正在从这个文件和这个答案一步一步地做,但没有任何作用.

这是我的截图:

这是我的Bridging-Header.h:

//
//  Use this file to import your target's public headers that you would like to expose to Swift.
//

#import 

#import "VKUser.h"
#import "VKAccessToken.h"
#import "VKCache.h"
#import "VKStorage.h"
#import "VKStorageItem.h"
#import "VKRequestManager.h"
#import "VKRequest.h"
#import "VKConnector.h"
#import "VKMethods.h"

#import "NSData+toBase64.h"
#import "NSString+Utilities.h"

重要的是我在一个文件中有VKConnector类和VKConnectorDelegate协议.也许这就是问题所在？

我试图将VKConnector头文件拆分为两个--VKConnector类和VKConnectorDelegate,但这不起作用.

我究竟做错了什么？
