How to Resolve Xcode Linker Warnings For Tests Target in App
提问by JeffB6688
The solution offered in Apple LLVM 6.0 Error: clang failed with exit code -1may work to resolve this problem, but as I stated at the end of my problem statement is that I did not want to remove the Tests target unless that is the only solution. So, is there another solution?
Apple LLVM 6.0 Error: clang failed with exit code -1 中提供的解决方案可能可以解决此问题，但正如我在问题陈述末尾所述，我不想删除测试目标，除非这是唯一的解决方案。那么，还有其他解决方案吗？
When trying to build a new app in Xcode, I am getting a ton of linker warnings. The warnings are related to a target that was automatically created called Tests. The expanded view of some of the warnings look like the following:
尝试在 Xcode 中构建新应用程序时，我收到了大量链接器警告。这些警告与自动创建的名为 Tests 的目标相关。一些警告的扩展视图如下所示：

What can I do to eliminate these warnings? Since I don't really understand how to use test cases yet, I'd rather not delete the target (but if that is the only option, I will).
我该怎么做才能消除这些警告？由于我还不太了解如何使用测试用例，我宁愿不删除目标（但如果这是唯一的选择，我会这样做）。

warning: Could not resolve external type c:objc(cs) xXX
The problem happens when you have a Xcode 6 project updated to 7. The short answer is to change the Debug Information Format to "DWARF", on the target, for the Debug configuration only.
当您将 Xcode 6 项目更新为 7 时，问题就会发生。简短的回答是将目标上的调试信息格式更改为“DWARF”，仅用于调试配置。
- Go to Build Settings and search for Debug Information Format
- Change the Debug setting from "DWARF with dSYM File" to "DWARF"
- Leave the Release setting at "DWARF with dSYM File"
- 转到构建设置并搜索调试信息格式
- 将调试设置从“DWARF with dSYM File”更改为“DWARF”
- 将 Release 设置保留在“DWARF with dSYM File”
This is safe because you don't need dSYM files for Debug builds
这是安全的，因为您不需要用于调试构建的 dSYM 文件
