【问题描述】：

因此，对于我的一个课程，我们应该从上一季度开始重构这个处于非常糟糕状态的项目。

所以我们正在尝试为项目编写单元测试，但他们使用的是旧版本的 Xcode，因此我们不得不将 XCTest 框架重新添加到“Link Binary With Libraries”中。

我第一次不小心添加了它的 MacOSX 版本，并注意到我的错误。我从链接器中删除了 OS X 版本，并向其中添加了 iPhoneSimulator 版本。它一直给我同样的错误。所以我从构建阶段删除了所有 XCTest.framework 文件，它给了我一个关于 OCMock 的错误（这是一个完全不同的问题，我现在并不关心），这意味着它知道它已经消失了。所以我然后尝试将 XCTest.framework 重新添加到我的测试目标中，确保它是 iosSimulator 版本，并且它给了我关于它是 Mac OS X 版本的相同错误。我已经尝试重新启动 Xcode 并正确执行了我之前所做的操作，但没有成功。以下是错误的完整输出。

【参考方案1】：

如果有人也遇到这个问题，几乎唯一的解决方案是创建一个新项目，并将所有文件添加到该新项目中。我与一些 iOS 开发专业人士交谈过，他们想不出其他解决方案。我认为这与来自相当旧版本的 Xcode 的项目有关，而新的 XCTest 框架相当新。如果你也遇到这种情况，祝你好运。
