XCTest.frameworkneeds to be linked only to the unit test target in your project. It should not be added to the UI application target.
XCTest.framework只需要链接到项目中的单元测试目标。不应将其添加到 UI 应用程序目标。
What I have found is when adding XCTest.frameworkXcode adds extra \to Framework Search Paths
我发现添加XCTest.frameworkXcode 时会增加额外\的内容Framework Search Paths
\"$(SDKROOT)/Developer/Library/Frameworks\"
\"$(DEVELOPER_LIBRARY_DIR)/Frameworks\"
$(DEVELOPER_FRAMEWORKS_DIR)
This causes linker issue,
这会导致链接器问题，

To resolve this issue in XCode 5.1 goto the main ProjectWindow, Tab Build Settings-> Section Search Path-> Framework Search Pathsand edit to remove \appearing the paths.
要在 XCode 5.1 中解决此问题，请转到主 ProjectWindow，Tab Build Settings-> Section Search Path-> Framework Search Paths并编辑以删除\出现的路径。
Hope that helps!
希望有帮助！

Deleting the test target and creating a new one and then copying the tests over can fix this.
删除测试目标并创建一个新目标，然后复制测试可以解决这个问题。

I suggest you to use xcode 5.02 stable version and then hopefully these Mac-O Linker errors will be resolved.same problems I am facing too before installing xcode 5.02.
我建议您使用 xcode 5.02 稳定版本，然后希望这些 Mac-O 链接器错误将得到解决。在安装 xcode 5.02 之前我也面临同样的问题。
