XCode在重复目标的pch文件中找不到自动生成的swift头moduleName-Swift.h(XCode cannot find auto-generated swift header moduleName-Swift.h in pch file in duplicate target)

 我复制了一个目标并获得以下构建错误：  
Resource/Prefix.pch:16:13: '<moduleName>-Swift.h' file not found
 
 我看不出会导致这个问题的两个目标之间有什么区别。  
 任何想法为什么会这样？ 

I duplicated a target and get the following build error: 
Resource/Prefix.pch:16:13: '<moduleName>-Swift.h' file not found
 
I can't see any difference between the two targets that would cause this problem. 
Any ideas why this is happening?

 问题是重复的目标具有不同的moduleName 。  
 我必须在重复的目标中添加一个C标志，并在Prefix.pch使用它。 （解析pch文件时，不会看到用户定义的设置。）  
 
#ifdef DEVLOPMENT_SERVER
    #import "<duplicateModuleName>-Swift.h"
#else
    #import "<moduleName>-Swift.h"
#endif

The problem is that the duplicate target has a different moduleName. 
I had to add a C-flag in the duplicate target and use this in Prefix.pch. (A User-Defined Setting doesn't get seen when parsing the pch file.) 
 
#ifdef DEVLOPMENT_SERVER
    #import "<duplicateModuleName>-Swift.h"
#else
    #import "<moduleName>-Swift.h"
#endif
