Question

我正在处理Xcode中的解析问题，该问题触发了一个失败的问题，而不是一个警告，并且几乎没有关于此的信息。它似乎与LLVM相关联，但由于我不是编译人员，所以存在什么样的技术文档对我来说没什么意义，并且存在哪些非技术性答案无助于解决这个问题。

我已经进入Organizer并删除了这个项目的派生数据，我确保所有可以设置到目标应用程序的文件都已设置，清理项目，搜索（futiley）'type-name'等。打开项目后立即出现此错误。这似乎是在我今天将项目签出到新机器上时开始的，但在我进行测试构建之前我没有注意到它。有什么想法吗？

我不仅在寻找能让我度过一天的答案，而且我还在寻找错误的解释，以便将来避免错误。 There is a "duplicate" question但是没有有用的答案，没有什么可以解释真正发生的事情

问题代码如下，错误标记在@interface OCSystemReportParser ()行。

这是有问题的标题......

#import <Foundation/Foundation.h>

@interface OCSystemReportParser : NSObject

- (void) parseSystemReports:(NSArray *)systemReports;

@end

......以及有问题的实施......

#import "OCSystemReportParser.h"

/*

 */
NSString* const OCKeyApplications = @"Applications";
NSString* const OCKeyHardware = @"Hardware";
NSString* const OCKeyMemory = @"Memory";
NSString* const OCKeySoftware = @"Software";


/*

@interface OCSystemReportParser () // ERROR IS FLAGGED HERE

// keywords whose data we need
@property (strong, readwrite, nonatomic) NSArray *actionableKeywords;
// lines for the current report
@property (strong, readwrite, nonatomic) NSArray *reportSource;

Answer 1

const NSString 

@interface OCSystemReportParser () // ERROR IS FLAGGED HERE

问题在于const NSString声明。它无效，或以分号结束，因此编译器表示它无法将@interface与const NSString合并为有意义的内容。

什么错误“解析问题：不能与以前的'type-name'声明说明符结合”真的是什么意思？
