问题

在原先是OC，之后进行OC 和 Swift 混编的项目中，通过Cocoapods集成 LXFProtocolTool/EmptyDataSetable 不报错，但在Swift文件中导入LXFProtocolTool后编译就会报错

尝试

• 尝试过新建一个 OC 项目，以相同方法 import LXFProtocolTool ，但是一点问题都没有~
• 也尝试过在Swift组件的.podspec文件中添加如下代码，但是也不起作用

s.pod_target_xcconfig = {'SWIFT_COMPILATION_MODE'=>'wholemodule'}

解决

在桥接文件中，将依赖的 DZNEmptyDataSet 导入之后再次编译就可以了

#import <DZNEmptyDataSet/UIScrollView+EmptyDataSet.h>
