我想在swift中使用objective C代码。一旦我添加了一个桥接头，我就开始得到所有原始数据类型的错误

Question

我有一个模型

@interface Section : NSObject
@property (nonatomic, strong) NSString *sectionId;
@property (nonatomic, strong) NSString *title;

+(instancetype)createObject:(NSDictionary *)sectionInfo;    
@end

我的桥接头如下所示

// MyProj-Bridging-Header.h    

#ifndef MyProj_Bridging_Header_h
#define MyProj_Bridging_Header_h

#import "Section.h"

#endif /* MyProj_Bridging_Header_h */

我的Swift控制器看起来像这样

@objc class SampleSwiftVC : UIViewController {
    var supportedSectionInfo: Section?
}

我开始收到编译时错误，比如

/*PathToProject*/Section.h:17:39: error: expected a type
+(instancetype)createObject:(NSDictionary *)sectionInfo;
                                  ^
<unknown>:0: error: failed to import bridging header '/*PathToProject*/MyProj-Bridging-Header.h'

我转到构建设置，发现头文件引用是为Objective-C Bridging header键设置的
