在Xcode中编译应用程序时无法解决的链接器错误

Question

我已经在一个应用程序上工作了一段时间，这给我在iPhone上的编译带来了麻烦。最近，它甚至停止了在模拟器上的编译。我已经浏览了堆栈溢出和其他网站的答案，但我似乎找不到解决问题的任何东西。下面是我正在犯的错误。

我已经恢复了整个应用程序的早期版本，看看它是否解决了问题，但它似乎没有任何区别。我还是会犯同样的错误。

有人能帮忙吗？

经过进一步的审查和修改，并在审查@damian提到的类似问题之后，解决办法似乎是：

我将应用程序和Podfile中的测试目标分隔开，使用

target :App do
…
end

target :AppTests do
…
end

这导致了两个新产品libPods-App.a和libPods-AppTests.a，他们使以前的产品libPods.a过时了。我不得不从两个目标的构建阶段配置的部分中删除此产品。

谢谢大家的投入！

尝试删除派生数据文件夹，重新启动Xcode并再次运行项目。转到Window -> Projects并导航到您的项目。应该提到您的派生数据文件夹。按Delete，重新启动Xcode并再次构建它。看看能不能把它又踢回高速状态。
